How To Adjust The Clutch On The Tiller
It should be noted that when working, you need to follow certain recommendations in order to avoid premature breakdowns and unnecessary problems, auto products due to improper handling of equipment. The clutch pedal must be pressed and released smoothly, without sudden movements. Otherwise, the engine may simply stall, then you will need to spend extra time and effort to start it again. During the operation of the tiller The following problems are possible related to the clutch mechanism.
- When the clutch is fully depressed, the technique suddenly begins to accelerate. In this situation, try simply tightening the adjusting screw.
- The clutch pedal is released but the machine is NOT moving or is not moving at an adequate speed. Loosen the adjustment screw slightly and test the running of the motorcycle.
In case of strange noises, crackling, knocking coming from the area of the gearbox, stop the unit immediately. The most common causes of this situation are considered to be low oil levels or poor quality. Be sure to check the presence and quantity of oil before starting to work on a Tiller. Change / add oil and start the unit. If the noise does NOT stop, stop the tiller and invite a specialist to inspect your equipment.
If you are having trouble shifting gears, test the clutch, adjust it. Then inspect the transmission for worn parts and check the shafts. splines may have worn out.
In order to repair the Agro Tiller clutch with your own hands, first of all, you should understand what kind of malfunction is in question, since a number of damages cannot be repaired at all and requires replacing the consumables. Consider the main options for faults:
Important! To replace any consumable item, it is required to completely dismantle the device from the tiller.
The 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 tiller;
- We put the standard tiller hub 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 rotate;
- Then Turn the crankshaft over and do the same on the back of it;
- Next, drill with a 5mm drill bit. Punch 6 holes in the pulley. The distance between them must be the same. Since 10 mm 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 drilling 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 the pulley back on and securely tighten the structure with bolts;
- Grind the inner surface of the crankshaft and flywheel so that they do not fight each other.
The finished structure can be installed on a regular place in the tiller. Do not forget to connect the cables, leading them as far as possible from the friction elements.
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 to improve vehicle maneuverability and ensure smooth cornering.
Together with the clutch, the differential regulates the rotation of the wheels of the tiller at different speeds. over, the power transmission mechanisms together 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 tiller 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 connected with the engine crankshaft. In most cases. Both the driving and driven elements are made in the form of flat round discs, or in the form of a cone. Just like the centrifugal clutch, the friction clutch is activated by manipulating a separate handle.
Element design and principle of operation
This mechanism, which, at first glance, has a complex design, in practice consists of only a few elements, namely:
- Release bearing.
- The basket where the disks are installed.
- The disc itself, which diverges under pressure into several SEPARATE components.
You can also note the presence of couplings and traditional bolt clamps, due to which the structure is mounted on the working plane. The clutch assembly is mounted above the transmission. This device allows the main gear of the engine to smoothly align with the gear of the transmission.
In the absence of a hitch or its damage, shifting becomes difficult, and at the moment of switching on, a metal crack is heard, since during operation it is difficult for the gears to combine at different speeds. In this case, the smoothness of switching is provided by the handle, which is the cable for one mechanism. This handle is released when shifting.
Here’s how to repair a clutch:
Important! Despite the simplicity of the mechanism, it cannot be said that the element can be easily replaced or repaired, in order to restore or change the structural component, you need to have some skills and experience.
Types of plows
Over the thousand-year history of the plow, it has often been modified. Modern units are usually divided by working bodies, their number and purpose.
- By working elements, plows are divided into share and disc.
- By the number of working bodies for one-, two-, three-body, etc.
- By appointment for special and general.
A share plow is a unit, the body of which is equipped with a share (knife). The ploughshare cuts the soil, lifts it up, and turns the blade over. The share aggregate is used for plowing the land for sowing grain crops. Maximum plowing depth. 30 cm.
Disc plow. instead of a ploughshare, the device has discs that plow the land. This unit is used on heavy rocky soils and fields, which are located in the place of uprooted forests. The advantage of the disc is that if the ploughshare finds it on a stone, it will break and the disc will roll over the obstacle. Disc devices are used only by powerful tractors in large fields.
A multi-body plow is a unit on which several bodies with shares are installed. The more powerful the tractor, the more bodies on one frame it can pull. Multi-body units speed up field processing and increase productivity. The heavy diesel tiller is equipped with two-body devices.
Special and general purpose plows. A general purpose machine is a share device that is designed for plowing a field. Special purpose machines are devices for difficult soil types, such as swampy, rocky, etc.
Single-frame plow mounted SCOUT PL-130 HYD with scoring disc
The single-body plow SCOUT PL-130 HYD is equipped with a scoring disc for more efficient work on sod soil. The unit is connected to mini-tractors and tillers with a single-point attachment mechanism. The working part is made of durable steel.
The angle of attack of the ploughshare is regulated with lanyards. The limiter wheel adjusts the plowing depth. The scoring disc is designed for cutting the roots of plants during plowing, which increases productivity and quality of plowing.
For plowing heavy soils and virgin lands, you need to install on the equipment weights of 80 kg in front and 60 kg in the rear.
How to plow with a tiller with a plow
Before starting to plow the area, a test plowing must be carried out, in which the adjustment of the device is checked. Check for what depth your machine is designed. When driving on furrows, check the plow operation. If the device does not work correctly, then adjust it directly in the ground. Assess the load on the tiller with the mouse and the correct gait.
If on trial plowing you are convinced that the technique is working correctly, then you can proceed with the mouse:
- We expose the unit at the border of the desired area, turn on the first speed and clamp the clutch. Pay attention that your steering wheel is parallel to the ground, so that the car goes straight ahead, and does not dig into the ground.
- The plowing process should take place without effort on the part of the operator. With a good setting, the technique itself moves and plows the area, and you only control it.
- After cutting the first furrow, measure the depth with a ruler or tape measure. If the depth matches the one to which you set the unit, then you can continue to work.
First furrow and blade angle
The last adjustment is the first furrow cut. After a trial plowing, it becomes clear whether the device is configured correctly. If the equipment does NOT slip and the unit sinks easily, then the plow is adjusted.
After cutting the furrow, the machine is lowered into the tracks with the right wheel. Then check the plowing depth and adjust the machine. Now you can start full plowing.
Frequent problems and solutions
Remember that plows are structurally different from each other. The general adjustment process is similar, but the elements for which the adjustment takes place may differ. Before starting the connection and setup, read the instructions that came with the device.
The same goes for the tiller. Specify, based on the instructions, whether it is necessary to change the wheels to lugs, and what diameter they should be. It is recommended to install weights on light and middle class tillers so that the unit sinks under the weight of the machine. If the plow is set up correctly, but the machine is still skidding, then the unit is too large for your tiller capacity. This problem can be solved by installing weighting materials.
When choosing a device, focus on the power of the tiller. The heavier the machine, the larger the diameter of the plow. Heavy diesel tillers are equipped with double-body devices, which increase the productivity of the processing of the site.
The design of the plow is simple and straightforward. the main thing is to be attentive to the unit itself and think sensibly when connecting it. Remember that the unit should be looked after in the same way as the tiller. Clean your implement after plowing, try NOT to plow Stony soils and service your helper in a timely manner.
How to choose a plow for a tiller
When choosing a plow, pay attention to the technical characteristics of your tiller. For processing small areas, a single-body share unit is suitable, and if you are the owner of a heavy diesel tiller, then you can connect a Double-body device, which will speed up the land cultivation process twice as compared to a single-body unit.
Adjusting the plow to the tiller
To work on different types of soil, the unit must be configured differently. But the main adjustment takes place according to several criteria:
- Setting the plowing depth;
- Adjustment of the angle of attack;
- First furrow cutting.
Plowing depth. Here is the setting of the plowing depth depends on the further process of growing crops. If you adjust the depth insufficient, the roots of harmful plants will remain under the soil, and if the depth is too deep, then the fertile soil will mix and the plants will NOT receive the necessary nutrients.
Attack angle. The adjustment takes place using a field board. The performance of the unit depends on the angle of attack: if the angle of attack is greater than necessary, the device will get stuck in the ground, and the tiller will skid; and if the angle of attack is insufficient, the plow will not remove the required layer of soil.
First furrow. After making all the adjustments, the first furrow must be plowed. At this stage, it becomes clear whether the plow is set up correctly. With the next mouse, the car is lowered by one wheel into the Track, and further adjustment takes place into the furrow.
Preparing the tiller for plowing
Land cultivation is a technological process that requires special preparation of motor vehicles and a plow. First, you need to move the car to the field to be processed. If you are using a lightweight tiller, then it can be transported in the back of a car. Before starting plowing, you need to carry out daily maintenance of the machine and check its performance.
For the period of plowing, lugs are installed on the light and middle class tillers instead of wheels. They improve traction and increase the total weight of the vehicle. Before installing the lugs, you need to transport the car to a flat area, substitute a stop under the rear hitch and remove the wheels. If you can replace the hubs on the Tilleri with longer ones in order to increase the Track, then replace them. After that, the lugs are installed. Pay attention that the tread pattern on the lugs is directed in one direction. Narrowing of the pattern indicates the direction of travel.
After carrying out maintenance and replacing the wheels with lugs, you can start connecting and adjusting the plow.
Sharpening the share
The main working element of the plow is a ploughshare (knife). The share carries the main load during plowing, because it is this element that cuts through the soil layer. Over time, the share dulls, which leads to a decrease in plowing performance. The unit must be equipped with a removable share.
If the cutting edge is damaged, the device stops easily sinking into the ground, and the tiller starts axle box. If the plowing process has deteriorated, then it’s time to make repairs. Correctly sharpening the ploughshare is possible only on special equipment that will heat the steel in order to make it plastic. After the steel is more plastic, it is straightened, cooled and sharpened. At home, you can use a tool sharpening machine. The share must be sharpened at a slight angle, from the side on which it crashes into the ground.
