DIY tiller creeper

Angular

The angular gearbox for the tiller ensures the docking of the engine with the transmission and the hitch. Another device is used, if it is modified. The corner device consists of the following parts:

flange;
flange fastening;
bearing;
body;
pulley;
belt;
washer made of steel;
fastening the pulley;
key;
rotary shaft.

You can make this device yourself. Before work, it is necessary to take into account the conditions in which he will work. These are radial and axial loads at the ends of the shafts. The load depends on the type of lubricant and temperature. It is best to choose a prefabricated case. Bearings of the correct size are selected for the shaft.

Chain

The chain device in its design necessarily has a chain. Sometimes it is found not one, but in the amount of several pieces. The gear chain slides over the sprockets and makes them rotate. The device is convenient in operation, has a reverse function and a high degree of reliability. The principle of operation is similar to the belt mechanism. Changing gear ratios is easy with changing sprocket sizes. They work like in a bicycle, but vice versa: the small one is the leading, and the large one is the driven sprocket.

Reliability of work is ensured by the quality of the metal sprockets and the strength of the chain. When making a gearbox yourself, you should take motorcycle sprockets, they are much stronger than bicycle sprockets. The device is simple and reliable, it has a reverse. The chain requires constant lubrication and tightening. Breakage is a common cause of gearbox failure. For repair, you need to change the chain.

Training

So, the tools and sketches are ready, you need to prepare the material for welding the body or take a finished one. You can weld from pieces of stainless steel. The prepared gears should freely enter the finished case. They can be borrowed from an old chainsaw. The Friendship brand or any other is suitable. The saw must be carefully disassembled and the whole gears must be pulled out along with the shafts. They are cleaned and washed, then sized according to the gear ratio.

When calculating the gear ratio, you should take the number of idle revolutions of the engine crankshaft as a basis and add 10% to them.

With any design of the product, imbalances between the details of the driven and driving parts must not be allowed.

Also, bearings must not be replaced with bushings. When parsing an old saw, this must be remembered.

Worm

The worm gearbox is widely used for completing mini-tractors and tillers. This model has gained popularity due to its long trouble-free operation and high reliability. The worm-type device has a reverse, allowing the unit to move in reverse. A distinctive feature of this converter is the presence of a special screw and worm wheel. The thread profile on the parts is trapezoidal. They are made of materials of increased strength.

The screw can have a four-way or two-way thread. It matches the thread on the gear. The teeth on quality parts are made of anti-friction steel. The efficiency of the device is high. Its advantages:

the gearbox allows you to extend the life of the engine;
creates little noise during operation;
the device consists of only 2 parts;
has a large gear ratio;
has a smooth ride;
high self-locking effect.

All positive qualities appear with precise assembly and adjustment of the mechanism.

Creeper

The traction of the soil tillage machine’s wheels to the soil can be improved by using lugs or a tiller creeper. The creeper is one of the hinged devices. It makes it possible to reduce the speed of the agricultural unit and increase the tractive effort together with the torque. An analogue of the gearbox works with the help of a chain and sprockets on the shafts. If desired, this device can be made by hand. Parts are used from other technology.

Each considered converter is endowed with its own shortcomings. To reduce their number to a minimum, you should try to make the device yourself. A self-made thing can become better quality and easier to use than a purchased copy.

Assembly

When assembling the product, the parts are carefully inserted into their places in the body and rotated. The housing must be hermetically sealed. This will keep dust and dirt out of the parts. Oil seals are installed on the shafts. Lubricant is poured into the housing. A home-made device is connected in the same way as a standard gearbox. To test it, start the engine and roll it on the ground. Details should work together a little.

Reducers for a tiller: what are there, how to make a creeper with your own hands, drawings, photos, videos

the tiller used by land owners consists of several units and parts. It is easy to operate. Users are often interested in the questions of what is a gearbox for a tiller, what kind of oil to pour into it, is it possible to make this device yourself.

Self-made creeper for tiller

Installing a creeper on the tiller helps to increase the torque by reducing the transport (not working) speed of the device. At the same time, the operating speed practically does not change, and the tractive effort increases, due to which a much larger area can be processed.

The process of making a creeper for a tiller with your own hands requires preparatory work.

Other design options

This tiller creeper gearbox is highly reliable. Unlike some other solutions, it has the ability to reverse, that is, the device can move in reverse.

This device is suitable for a tiller of medium or large (from 15 HP) power. For less powerful units, it is optimal to use a worm gear, which has a large gear ratio and, accordingly, gives a greater increase in torque. But the worm gear will not allow the tiller to move in reverse, and making it yourself is much more difficult. The finished blocks are non-repairable.

Required materials and tools

A creeper is a conventional reduction gear that increases torque by reducing engine speed. Such gearboxes exist of different types, for the tiller the gear is most suitable.

To assemble a reduction gear reducer you will need:

measuring and drawing devices for creating a drawing;
saw for metal;
drill with drills;
bearings;
pulley;
steel sheet 3-4 mm thick (steel ST3 is suitable);
finished case (from the generator);
bevel drive and ordinary driven gears;
driven and rotor shafts.

You will need a variety of bolts, nuts and washers for the mountings. In some cases, it is advisable to use a welding machine.

Assembly technology

The creation of a homemade creeper, like any other complex mechanism, begins with drawing up a drawing. This will help determine the technical indicators. what torque is planned to be achieved, how many revolutions per minute the rotor shaft should do, etc. At this stage, the main input parameter, from which one should start, is the standard power of the tiller.

At the preliminary stage, it is necessary to make or select a housing for the gearbox, since all moving elements of the creeper for the tiller must be closed.

In accordance with the diameter of the gearbox, the shells of the bearings must be cut out of the metal, which will be mounted on the drive shaft. The flange must be located on the reverse side of the gearbox, on the opposite side from the bearings.
Screw the flange to the generator body.
Put the driving gear on the rotor shaft, and the driven gear on the driven one. Dock them together.
Install the belt pulley on the driven shaft using spring washers and nuts.
Make sure that all parts of the assembled creeper are docked with the rotary generator shaft.
Put it in the case.
Check the mechanism in action.

Features of operation

After the creeper has been installed on the tiller, it is necessary to check its operation at least once every six months, periodically changing the oil in the bearings, lubricate the chains, pulley and “sprockets”. If the device is rarely used, but mainly in storage, then it should be provided with anti-corrosion treatment and high-quality preservation with the help of appropriate oil.

Before starting work, you need to make sure that the gearbox housing is closed, all elements are in good order and securely fastened together. During work, only shoes with a thick leather upper can be used.

The tiller creeper can only be wiped and lubricated when it is turned off and cold.

This device is classified as a hazardous source. Minors must not be allowed to work with him.

What is needed for the competent assembly of the travel reducer with your own hands?

Of course, it is much easier to purchase a ready-made factory version, but why overpay if you can design an equally practical home-made product in just a few hours. To be frank, this type of attachment painfully resembles a reduction-type gearbox, so there should be no problems with its creation.

Details for homemade tiller creeper:

pulley;
screws;
working case from the generator;
rotor shaft;
bevel gear;
flange bearing;
steel.

Those people who already have experience in designing assistive devices can easily create a new assistant for the tiller, while those new to this field should be patient and in no case give up.

DIY creeper for tiller and caring for him

Tillers have been considered for many years to be highly qualified and reliable helpers for the farmer. Attachments add considerable functionality, allowing you to turn the classic tiller into something more versatile and useful.

How to make an Auto Mechanic’s Creeper // Woodworking | I Like To Make Stuff

In today’s article, we will focus on a very curious creeper device that will help reduce travel speed. A similar feature will be relevant if the operating speed of the unit is slightly less than the transport speed.
By installing a creeper on the tiller, you can significantly increase the torque and improve the tractive effort.

The process of creating a creeper for a tiller

First you need to figure out all the components schematically, designate the torque indicator, power and decide on the rpm;
Then you need to choose a body for the future instrument. Often an element from a motorcycle is used in this role;
The next step consists of cutting out a shell of several bearings for the drive shaft that drives the gear. It is important to immediately pay attention to the gearbox diameter;
When choosing bearings, it is important to position the flannel on the other side of the gearbox;
Now you need to find the driven shaft, which acts as the basis for fixing the gear;
The self-made creation must be connected to the transmission mechanism and the shaft of the rotary generator;
The final touch is to secure the pulley to the driven shaft using spring washers and nuts.

After carrying out all these procedures, you can safely operate the creeper and evaluate all its practical advantages. But we must not forget that home-made devices are especially demanding in terms of care and diagnostics, because with a devil-may-care attitude, they will quickly stop working.

Safety requirements for creeper operation:

During the working process, it is necessary to wear only strong work shoes;
Before starting to use, it is imperative to make sure that all fasteners are securely connected;
It is necessary to lubricate all sprockets and chains with grease only before turning on or after turning off the engine (it is advisable to carry out this procedure at least once a year).

over, it should be understood that during short-term storage of the device, the creeper must be removed from dirt and dust, and also wiped dry. If it is planned that the equipment will be in the utility room for a rather long time, then it is necessary not only to clean, but also to cover all surfaces and fasteners with special conservation oil.

Creeper device

The design of the mechanism is quite simple from a technical point of view and includes:

body;
rotor shaft;
flange bearing;
bevel gear;
pulley;
steel parts and screws.

You can pick up a creeper for a tiller at any specialized point of sale of agricultural machinery. In the case of self-production, you can save money and leave a considerable amount of money for something else that is needed in the garden. Before making a structure, it is better to prepare drawings of all units with dimensions.

In this video, we will consider the installation of a creeper:

Required materials and tools

To begin with, you need to accurately determine the technical characteristics of the structure: the type of transmission, its gear ratio, the distance between the shaft and the axle of the wheelset. The work will need the following tools:

welding machine;
electric drill;
a set of files and files;
measuring instruments (vernier caliper, ruler);
yew;
hammer.

The tool must be visually inspected and checked.

Important! It is strictly forbidden to use a defective tool in order to avoid causing accidental injury to yourself and others.

Features of the

Small-scale mechanization in agriculture is very popular. tillers and cultivators are more often purchased for private farms. They allow you to carry out all the work on the processing of fields without significant costs for maintenance and operation of equipment.

Combined with the appropriate attachments, the Tillers are the best option for soil cultivation. The demand for these machines is due to the fact that they quickly and economically perform the assigned tasks, in contrast to bulky and outdated combines and tractors.

DIY creeper for tiller drawings

The time has passed when it was necessary to spend almost the whole day on cultivating a small plot of land and work for wear and tear. Well, who had a tiller. everyone in the neighborhood envied such a master. This is not the case now. The motorized agricultural mini-machinery occupies a leading position in terms of the number of sales. The additional equipment used in the tillers and the power of the mini-tractor allow you to successfully process large areas of personal plots. Extra strength is required when working on heavy soils. For this, a reduction gear or the so-called tiller creeper is widely used.

DIY Garage Creeper

They are installed together with pneumatic wheels and are practically not used on a wheelset with grousers. Reducing the rpm and speed of the tiller movement increases the tractive effort of the unit. It will not be difficult to make it yourself.

The creeper will allow your cultivator to cultivate any soil

How to adjust the speed?

Sometimes it turns out that you want to change the speed of movement of your motoblock device: increase or, which happens quite rarely, decrease it.

To increase the speed of movement of motoblock units, one of the following two methods is usually used:

replacement of wheels with large ones;
replacement of a pair of gears of a reducer.

The typical wheel diameter of almost all tillers is 570 mm. Most often, when replacing, tires are selected with a diameter that is approximately 1.25 times larger than this. 704 mm. Although the difference in size is relatively small (only 13.4 cm), the speed of movement increases significantly. Of course, if the design allows for larger tires, you can try to increase the speed gain.

The gear pair installed in the wheel reducer usually consists of two gears with 12 teeth for a small one and 61 for a large one. You can change this indicator by 18 and 55, respectively (only for specialists in agricultural machinery service centers), then the speed gain will be approximately 1.7 times. Do not try to carry out the operation of replacing the gears yourself: it is very important here to select not only high-quality parts with minimal errors, but also the appropriate pulley. The gearbox shaft retaining plate also plays an important role.

How To Make A Garage Creeper (ONLY 30!!)

Logically reasoning, reducing the speed of the tiller’s movement can be achieved by performing diametrically opposite actions. to reduce the diameter of the tires or the number of teeth on the gear pair.

A possible solution to increasing the speed is to adjust the throttle switch: when the machine is turned on, move it from the first position to the second. To reduce the speed of movement, return to the starting position. Of course, to change the speed downward, you do not need special reducers. it is enough not to switch to high gears.

Also possible solutions to the problem of increasing the tiller speed are replacing the motor with a more powerful one and upgrading or installing a clutch system (in some outdated models it is not provided).

It can help to increase the speed (especially on uneven terrain or heavy soils, where slippage of the equipment is frequent due to insufficient weight of the unit) and the installation of weights. They can be made with your own hands from metal parts. Weighting structures are installed on the tiller frame and wheels. For the frame, you will need metal corners, from which a self-made removable structure is formed, that is, you can easily remove it if not needed. Additional ballast weights are attached to this removable additional frame. The wheels need discs made of steel and solid iron blanks with a cross-section in the form of a hexagon. These parts are welded and inserted into the hubs. For reliable fixation, cotter pins are used, which are installed in specially prepared holes.

Of course, if there are no round steel elements at hand, you can replace them with almost any material at hand: reinforced concrete products or even flattened round plastic flasks, inside which sand is poured.

Do not forget about maintaining balance: the weights on the wheels must be equal in mass, and evenly distributed over the frame, otherwise there will be a skew, due to which, when performing turning maneuvers, your unit may fall to one side.

To accelerate the tiller with a trolley in bad weather conditions. snow, slush, soil soggy from torrential rains. you can put caterpillars (if the design allows). This method requires the installation of an additional wheelset and the purchase of rubber tracks of a rather large width. On the inner side of the track, restraints are attached to securely fix the rubber and prevent it from jumping off the wheel pair.

Do it yourself

How to make a creeper for a tiller with your own hands? The mechanism is very similar in design to a gearbox. Its inclusion in the work of the tiller redistributes part of the tractive effort to additional attachments. The work on the manufacture of the device can be conditionally divided into several stages:

Advice. You should take up the manufacture of home-made devices only if you have experience and when assembling, strictly adhere to the algorithm of the necessary operations.

How to reverse speed on a tiller

Let’s take a look at how to reverse the speed on the trailer. The presence of a reverse depends on the model and dimensions of the mini-equipment. You can cultivate the land with a motor cultivator, a light tiller and a heavy machine. It all depends on the goals and objectives set. Usually, when using models weighing up to 30 kg, there is no need for a reverse speed, moreover, it complicates the design of the unit. On a heavy machine without this function, it will be more difficult to do the job.

Agricultural machinery will not move without a gearbox. It happens:

The task of the bevel gear is to ensure the collision of the transmission with the engine, which affects the power of the gear. The gear is the transmitter between the motor and the wheels. The reduction gear serves to reduce the speed to increase power.

The reverse gear has a clutch located between the gears. They are on the main roller. The main task of this system is to ensure the reverse gear of the equipment. To make this mechanism yourself, the first thing you need to do is prepare a case, for which many use a two-inch fitting square.

You can use the generator shaft from the Ural motorcycle. The gears will fit from the Friendship chainsaw. In the shaft, you just need to drill a hole of the appropriate diameter. Mount another pinion shaft with bearings on the opposite side. And already on the weekend, fit a pulley to ensure rotation.

You can purchase a ready-made gearbox, only when buying it is better to give preference to more expensive mechanisms, since they are more reliable and last longer.

Among the malfunctions of gearboxes, users highlight the rapid wear of the gears and the fact that the transmission takes off.

If you increase the speed of the cultivator, then you need to take into account that wear will occur much faster. When doing land work, I want to quickly cope with the task. To increase or decrease the speed of movement, you can try the throttle stick. If the work is hard, then when the gas decreases, the engine will stall.

The first speed is used when plowing the land when more power is required from the machine. Faster work reduces the depth of cultivation.

The creeper is an integral part of the modern tiller. Its function is to change the number of revolutions of the output shaft, resulting in an increase or decrease in the engine torque of the agricultural machine.

Drawing

When planning the execution of work, you should always remember the importance of drawing up diagrams and drawings. It is advisable that they be done professionally. The drawing contains all the data for the manufacture of the model and its operation: the required torque, the number of shaft revolutions. He accurately explains the principle of interaction of structural parts.

Creeper device

The design of the mechanism is quite simple from a technical point of view and includes:

body;
rotor shaft;
flange bearing;
bevel gear;
pulley;
steel parts and screws.

The creeper will allow your cultivator to cultivate any soil

Do it yourself

Advice. You should take up the manufacture of home-made devices only if you have experience and when assembling, strictly adhere to the algorithm of the necessary operations.

Required materials and tools

welding machine;
electric drill;
a set of files and files;
measuring instruments (vernier caliper, ruler);
yew;
hammer.

The tool must be visually inspected and checked.

Important! It is strictly forbidden to use a defective tool in order to avoid causing accidental injury to yourself and others.

Assembly technology

After completing the design work and preparing the material, you can confidently proceed with the installation of the stroke reduction mechanism.

The assembly work boils down to the following:

All necessary calculations are performed to achieve maximum power and stable torque.
Prepare two bearings of the drive, which will set the movement of the gear.
Flange bearings must be located on the opposite side of the gearbox, inside which the washer is installed.
Install the drive shaft with the fixed gear.
Connect the shaft to the generator rotor and fix it with a spring nut.

The assembled structure is subject to testing. Including it in work, provided it is correctly assembled, the wheelset of the mini tractor should not spin so fast, and the tiller itself will be pressed to the ground.

Advice. Wheels that are too large in diameter will adversely affect the cultivator’s performance. Therefore, it is better to stop at a wheelset with a small diameter, about 25-30 centimeters.

If you plan to load the tiller with a plow for plowing hard soil, then the travel reducers should be made as powerful as possible.

The main rules, adhering to which, ensure reliable and long-term operation of a motorized installation:

after the first successful testing of the creeper, it is necessary to conduct a technical inspection of the mechanism once every 6 months, with the obligatory inclusion, replacement of the machine oil of the bearings, lubrication of the moving parts;
before working on a personal plot, you need to check the reliability of the fastening of the elements and the integrity of the mechanism body;
manipulations for wiping and lubricating the travel reducer are performed on the cooled off equipment;
children and minors are not allowed to operate the device in order to avoid accidental injury.

In fact, creating a tiller travel reducer with your own hands using ready-made drawings is not particularly difficult. Most of the parts can be obtained from other well-known agricultural machinery manufacturers. Of course, without proper experience, it will take more than one day before the desired mechanical unit is born. It is necessary to be patient and concentrate as much as possible, and the result will be a powerful mini tractor that will not stop before working in heavy soil and will perform it at a high level and in a short time.
