Do-it-yourself hitch for a walk-behind tractor
Often, sheets of steel or galvanized counterparts are taken for a homemade trailer for a walk-behind tractor. Sometimes they also use special reliable plastic. Naturally, metal sheets have a longer service life, but plastic counterparts will cost less.
When the material for a self-made trolley for a walk-behind tractor is selected, you can start drawing up a drawing, and diagrams of all supporting elements: a working body, a driver’s seat, and also a frame.
To do this work, you don’t need to be a mechanical designer, but a preliminary sketch must be drawn up correctly.
Why is it necessary to prepare carefully? When creating a trolley for a walk-behind tractor, you need to draw a model, indicate all complex areas, determine the dimensions, and also take into account all the nodes and connecting parts. The drawing must provide for running and supporting elements.
The driver’s seat must be correctly connected to the main module as well as the swivel head. It is necessary to attach all the necessary units directly to the walk-behind tractor using dumbbells and a console. Need to make a chain mechanism (axial rod).
The upper axle will serve as a support, and the pivot assembly should rotate around the axle on bearings, which should be protected with a good anti-dust cover. All voids around such bearings must be filled with a lubricant mixture.
Assembling the frame
The reliability of the frame is predetermined by the durability and strength of the hitch. This should be taken into account when creating a project for a future hitch. Thus, the following materials can be used in the manufacture of the trailer frame:
- Corner and rectangular pipe.
- The front and rear cross members can be made from a corner of 25×25 mm.
- For side members, a 60×30 mm pipe is an excellent choice.
- To connect all the elements, it is necessary to make five additional crossbars, forming a lattice-frame.
- Four vertical posts are attached to the longitudinal pipes of this lattice at the corners.
Making a one-piece trailer is pretty straightforward. Some homeowners decide to make more sophisticated devices. In such a situation, all subsequent actions depend on the choice of a specific type of trailer:
- On a tipper hitch, the tailgate must be hinged.
- If it is planned to manufacture a trailer with folding sides, then all three sides should have such a design, except for the front.
- The frames of the folding elements should be made separately from the general frame. For simple models, they can be its common elements.
Self-made trailing device for walk-behind tractor
Self-made trailing device for a walk-behind tractor with your own hands: photo and description of a homemade adapter.
For work at the summer cottage, a Forte HSD1G-105 diesel walk-behind tractor was purchased, (6 hp). We decided to make an adapter for the PV-01B trailer.
With a neighbor in the garage, we made a trailing device for connecting a walk-behind tractor with a trailer.
It turned out such an adapter.
We collect the chassis
You don’t need a lot of details to create a comfortable driver’s seat. The heavily loaded parts are the turn signal and also the drawbar, so they need to be reinforced with stiffeners. To attach the driver’s seat to the walk-behind tractor. you need a hinge.
As the saying goes, “you don’t need to invent a bicycle.” An excellent option would be a pipe-in-pipe design. Thanks to this connection, a semblance of a hinge system is obtained, due to which the wheelbase of the driver’s seat pivots on its own. This connection reduces the likelihood of deformation of the trailer bogie.
Install the driver’s seat to the central tube using bolts, as well as studs and locknuts. Pre-cut an oblong hole in the pipe for high-quality fixing of the bolt, and free rotation.
Springs, awnings and wheels are installed from any cars and sidecars, but in strict accordance with the expected loads. It is advisable to weld these parts to the beam, while the ends must be attached to the spar.
For the drawbar, a pipe with a cross section (60 × 30 mm) is often taken, which must be welded to the front of the side members. The edges must be welded to the drawbar. Thus, a kind of analogue of the factory version of the drawbar comes out.
Characteristics of standard trailers
A walk-behind tractor made in production, as a rule, has standard characteristics and dimensions, so it is also advisable to select a trailer for a walk-behind tractor based on certain parameters:
- For the lightest models of motoblocks, the trailer should have an average length and width of 1 meter. As a rule, industrial options have a size from 85 cm to 115 cm. The provided capacity of the trolley for a walk-behind tractor in such a case should not exceed 300 kilograms. Price from 200;
- In medium-sized motoblocks, the power of which is from 5 horsepower, the dimensions should not exceed (1 × 1.4-1.5 m), and the capacity should not exceed 500 kilograms. Such options cost from 250;
- For heavy models, trailers for motoblocks of a biaxial type 1.2 m × 2-3 m are provided, with a maximum carrying capacity of 1 ton. The price for such models ranges from 500 and above.
for a cart for a walk-behind tractor can be significant, so many agricultural owners, in order to save money, are trying to make a trailer for a walk-behind tractor. The construction of such a trailer is not difficult, but everything exactly for this work must be carefully prepared, take into account possible nuances and delve into the technology of further manufacturing.
How to make a homemade hitch for a walk-behind tractor
How to make a homemade hitch for a walk-behind tractor
If you decide to make a homemade hitch for a walk-behind tractor, then let’s get down to implementation. To manufacture this trailer, you will have to spend several days of work. The carrying capacity of the trailer was calculated for the weight of the transported cargo of 400-450 kg. When tested, the trailer easily held 6-7 sacks of potatoes.
There were no overload problems. The trailer was designed for the transport of goods in bags, therefore, folding sides are not provided.
We think over the constructive part of the project in advance. The trailer will consist of a sufficiently strong carrier, a body, a frame made of steel corners and reliable wheels.
- Bracket for mounted implements of the walk-behind tractor;
- Trailing device;
- The footboard, we use the s20 board;
- Driver’s seat, we use s20 board;
- Body, use s20 board;
- Support beam, we use three beams 50×50;
- Bolt M8;
- The ring is persistent, we use a pipe 58×4;
- Two wheels removed from the SZD motorized carriage.
The hitch for the trailer walk-behind tractor consists of several parts. We connect different parts by welding. The junction of the drawbar and the swivel part is the most loaded, therefore we strengthen this place with additional stiffeners.
For the manufacture of the frame, we use cuttings of pipes of round and rectangular sections, and steel corners. The design will turn out to be slightly intricate, but with an additional margin of safety. The reason was the difficult terrain and difficult operating conditions of the trailer.
For the brace, we use a corner 21x21x3;
2. The frame for the seat is also made from a corner 21x21x3;
3. The riser is made of pipe 50x25x4;
4. We make the seat racks from a 40x40x4 corner;
5 and 14. For the front struts, we use a 50×25 pipe;
6 and 15. For longitudinal side members we use a 40x40x4 corner;
7 and 8. The right wheel axle supports are made of a 32x32x4 corner;
9 and 16. We make the rear struts from a 50×25 pipe;
10. For the manufacture of a reinforcing cross member, we use a corner 40x40x4;
11. The body of the longitudinal hinge is made of 58×4 pipe;
12. For the manufacture of the wheel axle, we use a rod with a diameter of 30 mm;
13 and 17. For the transverse spars we use a 40x40x4 corner;
18. To make a scarf, we use metal s4.
If heavy loads on the trailer are not planned, you can make a simpler option.
- Swivel body;
- For the drawbar, we use the pipe 49×3, L1820;
- For the frame of the footboard, we use a corner 25x25x4;
- For an emphasis, we use a 58×4 pipe;
- For the stiffener we use s4 steel;
- For the lining, we use a strip of 25X4.
The trolley frame for the walk-behind tractor plays the role of its supporting structure. Dimensions and other elements are calculated based on its dimensions. Any inaccuracies must be identified and necessarily eliminated, because in the future, serious problems may arise when connecting various parts, corners, pipes and channel.
The most ideal solution for creating a frame is rectangular tubes with a cross section (60 × 30 mm). And for the traverse, you must use a square steel profile (25 × 25 mm). To make the structure more reliable, these elements must be welded, and also reinforced with special diameters, while it is necessary to leave protrusions above the side members.
For racks, a longitudinal profile must be welded to the front of the outlets on both sides. Next, you need to weld the upper trim of the racks with a cross section (25 mm).
It is necessary to choose the necessary materials according to certain characteristics, which provide additional strength, and also exclude the possibility of deformation under increased loads. A light trolley for a walk-behind tractor is made of rectangular or round pipes, as well as metal corners.
In order to make the best quality attachment of the trailer for the walk-behind tractor to its supporting structure, you will need the following elements:
- axial reinforcement 30 mm;
- racks for the driver’s seat (corner 40 × 40);
- solid triangle; brace (20 × 20);
- wheel axle stands (corner 32 × 32);
- corner (20 × 20) for the seat;
- front spacers (pipe 40 × 20);
- frame strapping (corner 40 × 40);
- rear braces (pipe 40 × 20);
- transverse reinforcement (corner 40 × 40).
A high-quality supporting structure is capable of providing the necessary margin of safety, and will allow transporting heavy and bulky goods on a trailer. In case of frequent use of the trailer for driving on rough terrain, such a frame will perfectly cope with the tasks set.
To ensure the highest quality connections, you need a welding machine, which will achieve high strength and durability.
Do-it-yourself universal hitch for a walk-behind tractor
The universal hitch is suitable for most models of walk-behind tractors, will provide aggregation with attached or trailed equipment without backlash. It is quite simple to make a coupling device, the main thing is to determine the tasks that it should solve, choose drawings and high-quality materials that ensure the strength of the unit.
Hitching a walk-behind tractor with a P-shaped trailer is suitable for most walk-behind tractors. The main point in creating a hitch is to match the size of the brackets of the walk-behind tractor and the hitch. A feature of the device with a bracket is that the attachments, aggregated with it with a walk-behind tractor, takes a position a few centimeters below the bracket itself, so it should not be at the level of the cultivated land.
On the Internet you can find many videos in which the owners of walk-behind tractors talk about the nuances of working with attachments, including how to make a hitch.
Types of motoblock hitch
There are the following types of coupling device for walk-behind tractors:
- Single or double, which are used depending on the amount of equipment attached.
- Reinforced, used for heavy cultivator models. Compared to the single or double version, this type of hitch of the walk-behind tractor is much thicker and longer, due to which the attachments will sink deeper into the ground, which will improve the quality of plowing.
- With an adjustable angle of rotation of the shaft, which will facilitate the placement of additional equipment at the required level, this will greatly facilitate the work with the cultivator.
- Versatile, suitable for several models at the same time.
But do not be upset if you cannot find a hitch for your cultivator. you can do it yourself. Some craftsmen are even able to make the entire walk-behind tractor with their own hands, so it will not be difficult to build an ordinary coupler. For example, a do-it-yourself hitch for a walk-behind tractor made from a crosspiece, used parts and spare parts. On the Internet, you can easily find drawings of couplings for a walk-behind tractor, the main thing is to correctly calculate the dimensions. The most popular is the U-type hitch.
How to make a do-it-yourself hitch for a walk-behind tractor: drawings and dimensions of a universal hitch, video
In some situations, you may need to make a do-it-yourself hitch for the walk-behind tractor. A walk-behind tractor is an essential attribute of any gardener. The purchase of a motor-cultivator is often accompanied by the purchase of related parts: a trailer, a hiller, a plow, a harrow and other parts. In order to attach them to the unit, a hitch is required. Now on the market cultivators are represented by a huge number of manufacturers, however, not for every unit you can find a suitable spare part, therefore you can make a hitch yourself.
How to make a hitch on a walk-behind tractor with your own hands
Consider how to make a do-it-yourself hitch. A homemade hitch for a walk-behind tractor will require the purchase of high-quality metal products, which can be channels, it will be necessary to make several holes in them. Or some car parts will do (the trailer hitch can be made from a cardan). If a reinforced mount is needed, then it must be stronger and larger than the usual variety.
Sleeve Hitch (Do it Yourself) for a Lawn/Garden Tractor. (Part 1)
The drawings on the Internet are different, so you need to choose the one that suits you.
To make a coupler you will also need:
- fasteners (steel pins, bolts);
- a lever that allows you to change the position of the hitch;
- metal welding to attach the shaft;
- drill and drill for metal;
- tape measure or ruler;
- screw installation wrenches.
So, a universal hitch for a walk-behind tractor includes the following components:
- Two U-shaped nodes of the same size, one of which is equipped with 6 holes, and the other. 8.
- A body (to create which requires welding), which has 2 threads: M12 and M16 and a connecting element with one of the nodes.
- Adjustment lever located in the body and consisting of a screw connected to the bracket and handle. In this case, the bracket must be directed up or down and not create any interference with the operation of the unit.
How to correctly position the connecting unit, you need to look in the instructions for the unit.
The hitch on the walk-behind tractor is attached with pins that are installed in the holes made in the nodes, while in quality they should be the same as the materials from which the hitch itself is made.
Do-it-yourself hitching to a walk-behind tractor is performed to connect not only a trailer, but also a plow, a hiller and other devices. At the same time, it will be possible to adjust it by adjusting it to a certain attachment.
Before starting work, the device should be checked, tighten all the bolts.
It should be noted that it is not difficult to make homemade couplings on your own, but it is better to purchase a unit by picking up the entire set of attachments and additional equipment for it at once, or at least make sure that such devices exist.
Consider how to choose a hitch for the Neva walk-behind tractor. Now you can buy cultivators from various manufacturers, differing in weight, size, quality and performance. Consider the Neva walk-behind tractor, which is especially popular among gardeners and gardeners, the production of which was launched in St. Petersburg back in 2002 at a subsidiary of OJSC Krasny Oktyabr, which produces aircraft.
In the production of motoblocks, Subaru, Briggs Stratton, Honda engines are used, which have an increased resource and efficiency, which contributes to effective soil cultivation. The device has a fairly simple and understandable gear shifting system even at first use. For the Neva walk-behind tractor, you can easily pick up various kinds of attachments manufactured for a specific brand.
The plant produces several models of motoblocks, while dividing them into 2 large groups, differing in the gearbox: classic and Multi AGRO.
The main category of users of walk-behind tractors are pensioners, so most often one of the inexpensive, but lightweight and high-quality models is purchased. MB-B6.5 RS Compact, which weighs only 70 kg, is well suited for processing sandy, loamy soils.
Using additional attachments for the unit, you can easily cope with the cleaning of the territory and with the transportation of goods, even over long distances.
On the Neva walk-behind tractor of this model, it is advisable to additionally purchase a support wheel, which will be useful when installing on the lug device, as well as to facilitate the work of loosening the soil due to the fact that it will not allow the walk-behind tractor to “bury” in the ground.
DIY motoblock plow hitch
The plow is one of the most important types of attachments for a walk-behind tractor. However, the manufacturer does not always provide a hitch in the kit. It is not difficult to make a hitch for a plow with a walk-behind tractor; you can use the simplest drawings of the U-shaped hitch.
Depending on what power the walk-behind tractor has and what kind of land the plow will work on, a more or less durable hitch will be needed. There is always a tremendous load on this node, so it must be made of high-quality materials, especially if heavy soil is to be worked.
What type of hitch for attachments and trailed implements do you use??
For example, a harrow or a potato planter can be used as a hitch. These devices belong to the first category. Landing and steering mechanisms are ranked as the second type. In other words, this is equipment that is only intermediate between the walk-behind tractor and any other device. These items are considered universal and are often referred to as adapters.
Trailers deserve special attention. It is believed that this is a highly specialized technique, since it can only be used for the transportation of goods. In fact, you can use a trailer to transport almost any item, which significantly expands the functionality of the device. It is also worth noting that it is the trailer that is a prime example of an adapter that has an elongated shape, at the end of which there is a wheelset. A capacious body is installed on top of this element, which serves to transport goods. Currently, there are many different variations, differing in shape, maximum carrying capacity, type of wheelset.
Here it is important to start with the fact that all equipment that is attached to the front of the walk-behind tractor is considered to be attached. Trailed devices are all elements that are connected to the device using a special hitch located at the back. When making a do-it-yourself trailing device for a walk-behind tractor, it is important to consider one more fact. This group falls into two categories. The first category includes highly specialized equipment, and the second category. multifunctional.
What you need to know?
In order to successfully operate a trailer or other device, it is very important to have a strong hitch element. It is he who is the trailing device with which the equipment is moved due to the power of the walk-behind tractor.
There are a lot of options for making a trailing device for a walk-behind tractor with your own hands, but it is best to use the simplest and most functional. It is necessary to use high-quality steel as a material for manufacturing so that it can withstand enormous loads. It is best to use a channel to create a hitch if it fits in size and thickness. A simple option is the U-shaped hitch for a walk-behind tractor.
To install the towbar with your own hands, do the following. The brace of the device is aligned with the corresponding mount. It is usually located under the steering wheel of a walk-behind tractor. After that, the mount is fixed with a pin. The most reliable option is the use of a spacer bolt with dimensions of 12 by 60 mm.
After that, it is necessary to mount the removable axle of the hitch on a plow, trailer or other. To fix the hitch with your own hands, you must insert a threaded axle with a diameter of 16 mm into the hole obtained. A screw is screwed onto this element. It is also necessary to drill holes on the sides, into which bolts measuring 16 by 40 mm are also inserted.
Do-it-yourself hitch for a walk-behind tractor: drawing, recommendations for manufacturing
Before moving on to the question of how to make a tow hitch, you need to figure out what they are. The thing is that the walk-behind tractor has clutch assemblies both in front and behind. In this regard, there are various devices that can be connected. In addition, the equipment differs in its functionality.
There are a huge variety of different devices on the market that are used to hitch a walk-behind tractor and any device. It is only important to choose the right one so that it fits the specific adapter. However, if this is not possible, then it is quite possible to make a towing device with your own hands. Although this process will take a lot of time and effort, the result is worth it.
It is very important to remember a few basic rules here. The very first thing. this is the engine power of the walk-behind tractor. If a do-it-yourself hitch is too heavy, then, naturally, the walk-behind tractor will not move it. Most often, a do-it-yourself hitch is made for a car with dimensions of 1 by 1.15 meters. Using such a trailer, you can transport no more than 3 quintals of cargo at a time. If the engine volume of the walk-behind tractor is 5 liters or more, then the dimensions of the trailer can be increased by 25-35 cm.
If the farm uses a very powerful walk-behind tractor, the dimensions of the hitch can be increased up to three meters. However, in this case, most likely, you will have to install an additional wheelset and reinforce the body. In addition, you will need to use more durable and expensive materials in the production of a do-it-yourself trailing device for a walk-behind tractor.
The most important point, as mentioned earlier, is the material from which the hitch for the walk-behind tractor is made. In this case, he will decide everything. Therefore, it is recommended to carefully select the raw materials.
In the selected piece of material, you need to make several holes through which the parts will be connected using fasteners. You also need to have a bracket on hand, which will also be used to make the hitch. Experts recommend bending its long end either up or down so that in the future it does not interfere with the next steps. However, here it must be borne in mind that under no circumstances should he touch the ground.
Another simple but important tip. this is to take the factory model as a sample. If in the future you need to attach a non-standard attachment to the walk-behind tractor, you will have to use an adapter.
The simplest construction of motoblock homemade products is called a pipe-in-pipe coupling. It is made according to the following principle. A pipe with a smaller diameter must be welded to the end of the workpiece. It is with the help of this part that the coupling will take place. Another element of similar dimensions is welded from the opposite end. This part will serve to connect the walk-behind tractor directly. This type of attachment is considered not only reliable, but also provides excellent mobility.
Do-it-yourself hitch to a walk-behind tractor, photos, drawings
One of the important components of the units, which ensures a reliable connection of the trailed equipment with the walk-behind tractor, is the hitch. There are different types of hitch assembly. However, the most commonly used is the U-shaped hitch assembly of the walk-behind tractor. This unit is manufactured both industrially and independently. If a do-it-yourself hitch to a walk-behind tractor is made, it must be strong in order to be able to withstand heavy loads.
Installing a hitch on a walk-behind tractor
The hitch bracket is installed on the walk-behind tractor bracket, and is attached with pins. It is advisable to fix the hitch bracket with M12x60 spacer bolts, swivel to the walk-behind tractor frame.
Attaching the implement to the hitch
A removable hitch axle must be installed on the implement rack bracket.
Insert an axle with an M16 thread into the hole in the hitch body and screw a screw into this thread.
It is necessary to match the holes for the M16x40 bolt on the tool stand and on the hitch body. Then this connection is fixed with an M12 nut and an M12x40 bolt.
Do-it-yourself hitch to a walk-behind tractor
The U-shaped mount is at the heart of the hitch for the walk-behind tractor, therefore, to make it, a channel of suitable thickness and size is perfect. This mount is located under the steering wheel of the walk-behind tractor.
When making a do-it-yourself hitch mount, you need to drill several holes in order to fix the bracket and the mounting pin in them. Therefore, the holes must be of the correct diameter. The pin also needs to be made of high strength steel.
To attach additional accessories to the walk-behind tractor, you will need a bracket. The long end of the bracket should be either downward or upward to avoid interference with connected equipment. In this case, the end of the bracket should not touch the surface of the soil that we are processing.
When making a homemade hitch assembly, we used a standard sample. Often, additional devices are used for the walk-behind tractor, with non-standard types of coupling. To connect them to the walk-behind tractor, you either need to purchase a special adapter, or make an adapter yourself. As a rule, these are U-shaped brackets.
Drawings of the hitch of the walk-behind tractor
Consider a drawing of a universal coupling for the following types of motoblocks: “Pubert Quatro”, “Honda”, “AGRO”, “OKA”, “KASKAD”, “MB-90”, “NEVA”, “FAVORIT”, “SALUT”.
Purpose of the universal hitch in conjunction with a walk-behind tractor of attachments: a digger, a plow, a one- and two-row hiller, etc.
Recommendations for work
Attached implements are configured and regulated individually, depending on the type of soil and power of the walk-behind tractor. The special design of the hitch can be adjusted in different ranges. Using the initial settings, you need to set the radius grooves of the hitch to zero, the transverse grip angle, and fix it with an M12 nut and an M12 bolt. Also set the longitudinal grip angle to a minimum. The first 3-5 meters of movement, carefully observe how the walk-behind tractor works with the tool.
If you need to deepen or raise the implement, stop the walk-behind tractor, and adjust the implement by turning the screw handle. Then you can continue driving and evaluate how the walk-behind tractor works with the tool. Also, if you need to adjust the transverse grip angle, you need to loosen the M12 nuts and M12 bolts.
Then adjust the angle in the required direction and tighten the nuts and bolts. Before starting work, all threaded connections must be tightened firmly. After the work on the soil is over, the threaded connections must be cleaned and lubricated daily. To do this, use Litol 24.

How to make a clutch mechanism with your own hands?
The clutch on the walk-behind tractor works on a principle that provides for increased friction of the components, so rapid wear cannot be avoided. In this case, you should try to make the mechanism yourself. The homemade clutch design will be composed of:
- the input shaft of the gearbox and the flywheel of the Moskvich car;
- hub and steering knuckle from Tavria;
- Two grooved driven pulley;
- Crankshaft from GAZ-69.
Walk-behind tractor clutch. device, principle of operation and do-it-yourself manufacturing
The clutch of the walk-behind tractor is an important element of the transmission, through which the crankshaft of the engine transmits torque to the gearbox mechanisms. With the help of this part, during gear shifting, the engine and gearbox are disconnected. It is due to the participation of the clutch that the walk-behind tractor smoothly starts from a place, and also stops without completely turning off the motor.
Centrifugal clutch. design and benefits
This kind of element should be distinguished from other structures due to its reliability and durability. It is used in automatic gearboxes. Its design consists of the following elements:
- Hubs with locking groove and key;
- Retaining ring.
One of the most important roles is played by the differential device associated with the centrifugal clutch. It helps improve vehicle maneuverability and smoother cornering.
Together with the clutch, the differential regulates the rotation of the wheels of the walk-behind tractor at different speeds. over, the power transmission mechanisms work together to act as wheel blockers. In some models of equipment, instead of a differential, a special device is installed that locks one of the wheels of the walk-behind tractor at the command of the driver.
modern models of equipment are equipped with a friction clutch. It is mounted between the motor and the gearbox. In this design, the driven parts are closely connected with the input shaft of the gearbox, and the leading parts are closely related to the crankshaft of the engine. In most cases. and the driving and driven elements are made in the form of flat circular discs, or in the form of a cone. Just like the centrifugal clutch, the friction clutch is activated by manipulating a separate handle.
How the clutch works
A clutch for a walk-behind tractor consists of several important elements:
- Control devices;
- Leading element;
- Driven parts.
The driving part consists of the end face of the engine flywheel and the pressure plate. The disc rotates with the attached flywheel. At the same time, the disc can also move axially in relation to the flywheel. Between these two elements is the driven disc, which is located on the driven shaft. Spring elements in the form of cylinders are located around the perimeter of the pressure plate.
The function of the springs is based on the compression of the disc they support. In this case, the other end of the springs contacts the casing. Thus, the springs maintain the clutch for the walk-behind tractor in a constant on state.
The control mechanism is made of release levers, connected to the body of the pressure discs by means of rods with a deflector and a pedal. Disengaging the clutch, the owner of the walk-behind tractor engages the clutch cable, which transmits force to the release levers. When the springs are compressed, the levers move the driven disc away from the pressure plate, which disengages the clutch.
The bearing reduces friction by preventing the stationary leg from touching the rotation levers. Most models of walk-behind tractors are equipped with three levers located at an angle of 120 degrees in relation to each other. Each clutch lever is returned to its original position by a spring. In this case, the layering moves to the distance required to turn off the levers. If this distance is not reached, then the clutch starts to slip.
Clutch functions in the design of the walk-behind tractor
The clutch operation is based on the action of the friction clutch. This transmission element performs several important functions, among which it stands out:
- Uninterrupted transmission of torque;
- Suppression of torsional vibrations;
- Smooth gear shifting;
- Shockless gear connection;
- Connecting and disconnecting a gearbox with an internal combustion engine;
- Disconnecting the Transmission from the Flywheel Assembly.
The clutch device makes it possible to briefly disconnect the engine crankshaft and the power train of the machine. Thanks to the clutch, the vehicle starts and stops moving smoothly and without jerking.
Subsequent work on the assembly of the mechanism is as follows:
- First you need to grind the crankshaft so that it does not cling to other elements of the walk-behind tractor;
- We put the standard hub of the walk-behind tractor on the shaft;
- Further on the shaft it is necessary to groove a place for the bearing. This operation should be performed as accurately as possible so that the bearing fits perfectly on the shaft. As a result, the hub should fit without any gaps, and the pulley should scroll;
- Then turn the crankshaft over and do the same on the back of it;
- Next, drill 6 holes in the pulley with a drill with a 5mm drill bit. The distance between them must be the same. Since 10mm bolts will be used, holes must also be drilled on the back of the wheel driving the drive belt;
- Next, install the pulley on the flywheel, and tighten both parts with a bolt. Then mark the drill spots on the flywheel so that they line up with the 6 holes in the pulley;
- Remove the pulley and drill holes in the flywheel;
- After that, put on the pulley again and securely tighten the structure with bolts;
- Grind the inner surface of the crankshaft and flywheel so that they do not hit each other.
The finished structure can be installed on a regular place in the walk-behind tractor. Do not forget to connect the cables, leading them as far as possible from the friction elements.
Trolley for a walk-behind tractor: a do-it-yourself hitch, a wheelbarrow and a cart, how to make a homemade trailer 0 drawings and dimensions
In the household, every saving opportunity is good. And in order for this savings to be useful, it is necessary that it would also pay for itself over time. Thus, all hand-made technique will bear fruit over time. Including a homemade cart for a walk-behind tractor.
The usefulness of such a product is difficult to overestimate, and if it is also designed by the owner himself, it will become one of the best assistants.
If you start comparing factory carts for walk-behind tractors, their will seem simply exorbitant, given that such a product will be used in a limited area and along a simple route.
Although their quality still attracts the attention of many owners of walk-behind tractors, who, for one reason or another, do not manufacture them at home. Although there is something to see. galvanized sides and bottoms, brakes for every taste and soft seats with footrests. almost all types of comfort.
You can even get a product warranty. But, since they are all manufactured according to certain standards, their dimensions, carrying capacity and general design convenience often do not meet the needs of customers. Therefore, the question of choice is a serious one. to buy or to do it yourself?

- In order to use the cart together with the walk-behind tractor, you will need to supplement it with the necessary fastening. Average.
A trailer is a trolley, which, despite the name, can be used not only with walk-behind tractors of this company, but also with their counterparts. And there are plenty of them, since, like walk-behind tractors, it is made in China.
The products of this country are known for the fact that different models and even companies use the same components, thanks to which it is possible to carry out repairs by replacing parts in similar models.
The same applies to attachments, or rather mounts for it.
The device of the cart for the walk-behind tractor
The simplest version of a trailer, carts for a walk-behind tractor is a monolithic block that is placed on the frame grid. For manufacturing, you need traverses, pipe spars. 4 racks are attached to the pipes located along the structure.
And already to them (to their upper block), straps made from a corner are welded. In the event that it is necessary to supplement the trailer with folding-type sides, the frames must be made separately from the supporting frame. The platform lattice is best covered with a sheet of duralumin, bolting it.
For the construction of the sides, thin sheets of metal are used, fixing them by welding.
Depending on what the dimensions of the cart for the walk-behind tractor will be, you can make several options for the beam to which the axle with wheels is attached. For a large trailer, only a prefab is suitable, which consists of two channels inserted into each other and welded together.
For a small cart, small in size, you can do with a square profile. Such a device will allow performing the simplest functions of transporting goods and passengers. A cart equipped with springs for a walk-behind tractor, photos illustrate their prevalence and popularity.
Due to the fact that they are very easy to manufacture and repair, and the folding sides facilitate loading and unloading, these carts are widely used in all farms where almost any walk-behind tractor is available, be it Luch, Tarpan, Mole, Zubr, Niva, Salut, Lifan 6.5, Husqvarna, Carver or some other.

How to make a homemade cart. step by step with drawings and dimensions
As the drawing of the carriage for the walk-behind tractor shows, the structure has four main nodes that are connected together using welding seams: the body, the carrier, the frame and the wheels. All nodes are first assembled separately, and only then connected together.
The product frame is manufactured first. It must be set as evenly as possible, using a level and put on potholders. The metal expands from heating, so it will need to be re-exposed. Next, you need to scald all the joints of the frame on both sides.
Next, the cross members and spars are welded, which form a kind of mesh on which, as a result, the bottom of the trailer will be attached. The body doors can be made not sliding, or folding. both options have their pros and cons.
In any case, it is necessary to attach fasteners to the sides of both options to fix the load.
The carrier, one of the undercarriage assemblies, can be made of channels, or pipes with a circular cross-section. The pipe must have a sufficiently thick layer of metal, and be strong. it will be difficult to additionally strengthen it along its length. It is firmly fastened to the trailer axle using several beams and angles.
This mount is very important because it essentially maintains the balance of the entire chassis. thanks to it, the cart goes where it is directed. And at a certain moment it is subjected to heavy loads. at the moments of turns with a full, loaded trailer and while driving on uneven roads.
How to attach?
An important question for owners of motoblocks with trailers is the method of coupling. Many, having quickly figured out the problem of how to attach a cart to a walk-behind tractor, did not take into account the fact that with constant movement, the holes with which the connection was made break.
The result is backlash, which has an even more detrimental effect on parts. and as a result, they need to be replaced.
But although it is not difficult to replace the fastening on the trailer, it is enough to simply weld on, using electric welding, an additional layer of metal, or simply replace part of the drawbar, with the fastening of the walk-behind tractor it is more difficult to do.
The factory mount for attachments is also used to couple the walk-behind tractor with a trailer. It is securely fixed in the structure if a breakdown occurs, then a simple repair cannot be done. it needs to be completely replaced.
You can find them cheaply, or even free, if you know where to look. there are ball joints in any car.
As for factory-made couplings, which will definitely cost more, but do not require adjustment. boring, welding and rust cleaning, they can be found at any point of sale of such equipment.
They are of different types, and are divided by type: semi-mounted, trailed and mounted, according to their purpose they are divided into special ones, which are suitable only for the installation of specific equipment. There are also universal models that fit any type of motoblock couplings, such as Champion, Plowman, Profi, Hooter, Don, Sadko, Forza, Viking and any attachments.
They are a device that consists of several frames connected by hinges.
For a heavy walk-behind tractor, a single reinforced hitch can be used, with which you can install paired implements with a similar double hitch. The universal hitch is used to connect the trailer itself, and paired attachments.
Also, there are special couplings, in the form of two U-shaped mounts, which are connected using a square profile. They have very little in common with hinge type couplings and are connectors for several types of attachments and trailers.
Such couplings are, first of all, good for their reliability. They are constructed from thick steel to withstand heavy loads, and their design allows them to work at different angles without compromising their integrity.
From homemade parts, such products are distinguished by their small size and low weight. In addition, some of them provide the ability to adjust the length and height of the departure, depending on what type of trolley is used.
In the event that the hitch for some reason does not fit into place, it remains possible to install an adapter with a hook. Thus, the hitch to the walk-behind tractor to the cart can be of different types, but it can successfully fulfill its function. It all depends on what kind of product you prefer.
How to do it yourself?
Before you make a cart to the walk-behind tractor with your own hands, first of all you need to have an idea about it. to roughly understand what its appearance and dimensions of the future product should be.
After that, it is necessary to start counting the rolled metal. the number of channels, angles and pipes and profiles from which the future trailer will be made. After careful consideration of the issue, you will not only optimize costs, but also be able to get a clearer picture of the future product.
The Kamaz 4310 truck is widely popular because of its power, performance, extraordinary passable ability and reliability. Here is an article about this beautiful car.
The lineup of MTZ tractors is distinguished by high quality and reliability of each model. Here is everything about their technical features, characteristics and prices.
The Tatra car brand is a true patriarch in the family of self-run strollers. Dump truck Tatra T815 is a real workhorse for Russian off-road.
And at the time of purchasing materials, it will be easier for you to deal with it. you can cut them to the desired size right on the spot. Also, you definitely need to get a welding machine if you do not have your own personal one. all frame connections need to be welded well.
In no case should it be connected with self-tapping screws, since they do not provide a sufficient level of reliability. In order to make a solid frame, corners with a cross section of 5025 millimeters and 4040 millimeters are ideal. Pipes are also needed, both round and rectangular.
A very important and rather complicated part of the whole structure is to do the fastening of the cart to the walk-behind tractor with your own hands.
The swivel unit of the carrier, of which the console is a part, is needed so that the trailer moves in all planes, regardless of the walk-behind tractor.
This is an important and necessary detail, since most of the time this structure will not move on a flat highway, but over rough terrain, where there are no roads, but only directions.
The console must be attached to the attachment bracket, therefore that part of it for which the trailer will need to be hooked must completely repeat the shape of the hiller.
The process of how to make a hitch to a walk-behind tractor cart is not very complicated, but it requires some care of the master for installation. the drawbar in the tubular body of the longitudinal hinge is attached using a retaining ring.
After installing and fixing all these parts, driving a walk-behind tractor with a trailer will become very convenient and pleasant for the driver. All that remains is to fix the seat and the footrest. and now, the product is ready for use.
