The horizontal shaft of the Subaru engine transfers the load to the working tool more fully. The operation of the mechanism is accompanied by less noise, thanks to the engine. The engine is mounted on the frame, the connection with the gearbox at the bottom is a belt drive. The Cayman cultivator gearbox transmits torque from the drive chain to the driven sprocket. If the model is equipped with reverse, reverse, a tapered coupling is installed on top. The axle of the driven sprocket extends beyond the gearbox housing, which allows the lugs and wheels to be installed. At idle, the Cayman cultivator belt does not transmit torque to the clutch. To do this, you need to squeeze the clutch on the handle, apply tension. In this case, the tension roller changes the trajectory of rotation of the belt, and it transfers the force to the gearbox.

The design features of the mechanism allow you to cultivate virgin and fallow lands. However, the knives of the Cayman cultivator are not sharp, so they tear the roots of bushes and perennial weeds on the way without chopping.

Nearly all models are reversible for precise implement control and steering. However, models adapted for working on dense soil and virgin lands cannot be light, and their weight is 46-57 kg. Transportation by car of equipment is difficult.

Fortunately, they have a relatively simple design, and you can even carry out simple repairs with your own hands. To do this, you need to learn how to determine which part of the walk-behind tractor is out of order, and what needs to be done to restore the operation of the equipment. Our article will help you with this, which not only describes the principle of operation of the walk-behind tractor, but also the main causes of equipment malfunction and how to eliminate them.Most of the models consist of the same parts, so you can do the repair of the main components yourself. Image - Do-it-yourself caiman cultivator gearbox repair

Figure 1. Standard drawing of a walk-behind tractor

Each walk-behind tractor consists of a base frame, a gasoline or diesel engine, a fuel tank, a rotor for attaching cutters, wheels and a bracket for fixing attachments.The most important component is, of course, the engine, on the successful operation of which the operation of the equipment will depend (Figure 1). In addition, modern models have fuel supply, cooling, ignition and gas distribution systems, and the occurrence of malfunctions in them can also lead to a shutdown of the unit.

The main function of the walk-behind tractor is to loosen the soil using special cutters that are attached to the frame of the device.

Note: Unlike a conventional plow, the cutter does not overturn the soil and prevents soil erosion.

In addition, the technique can be used to loosen row spacings in the process of growing agricultural crops, and special attachments are useful for harvesting. Simple models (cultivators) consist of several wheels and handles that are used to control the machinery. On the handles there are buttons necessary for control. More powerful and modern models are mini tractors without a cab. In this case, control is carried out by buttons and pedals located on the dashboard.

Despite the fact that walk-behind tractors are produced by a wide variety of manufacturers, it is customary to divide all such equipment into types depending on weight and power (Figure 2).

According to this criterion, walk-behind tractors are:

Ultralight - weighing up to 15 kg;
Lightweight (about 40 kg);
Medium - from 45 to 60 kg;
Heavy (over 60 kg).

Figure 2. The main types of machinery and attachments

As a rule, all types of equipment are supplied with an internal combustion engine with a capacity of 1.5 to 10 horsepower. This is necessary in order for even the ultra-light model to successfully cope with loosening the soil in areas with heavy and dense soils.

Since the main part of any technique is the engine, the main number of breakdowns is associated with it (Figure 3). In some cases, poor engine performance may be associated with poor-quality fuel or dirty air filter. There are also cases that the engine does not work properly due to insufficient heating, malfunctions of the ignition system, carburetor or pistons.

Figure 3. Main engine parts

We will try to understand the main types of damage to the walk-behind tractor, which can be eliminated with our own hands. However, if you are not confident in your own abilities or fear that it is impossible to eliminate the malfunction on your own, it is better to contact a specialist.

If the engine does not start when you try to start, there may be a problem with the engine itself or its starting system.

To troubleshoot fuel supply problems, do the following:

Check the spark plugs: if they are dry, there is no fuel entering the engine cylinders. Such a malfunction can occur when blockages form in the gas tank cap, debris gets into the fuel supply system, when the supply valve is closed or the banal lack of gasoline.
Refuel the tank and try to start the engine again.
Check the fuel cock: if closed, it must be repositioned to open.
Clean the fuel tank drain hole.
Drain the gasoline tank, remove the fuel cock and rinse it with clean gasoline.
Remove the connecting hose near the carburetor and blow it out (together with the jets).

If all these manipulations did not help, and the fuel enters the carburetor, but does not enter the cylinder, then the malfunction is in the carburetor and this part must be carefully examined.

A common cause of carburetor malfunction is blockages. In this case, it is enough to disassemble the part, remove the source of pollution and reassemble. The instructions, which are necessarily provided by the manufacturer, will help you with this (Figure 4).

Figure 4. Diagram of the carburetor

The main purpose of all manipulations with the carburetor is to adjust the immersion of the float, which is attached with a bracket to the piston system. It often happens that the bracket is deformed, the float does not sink correctly and the carburetor does not function properly. The bracket is adjusted with an ordinary screwdriver, both with the needle valve open and closed.

After correcting the carburetor, it is recommended to also check the serviceability of the valves. It is necessary to check the tightness of each of them and, if necessary, restore the optimal clearance.

It often happens that during the operation of the walk-behind tractor, extraneous noises appear in its gearbox. As a rule, this is due to an insufficient amount of oil in it, and to eliminate the malfunction, it is enough just to add fluid to the gearbox (Figure 5).

However, if there is enough oil in the gearbox and the noise persists, the brand and grade of oil may not be suitable for your model. In this case, the oil must be completely drained, the system flushed and refilled with new, more suitable oil.

Figure 5. Gearbox diagram

In addition, extraneous noise may be associated with insufficient fixation of the transmission elements. They must be inspected and, if necessary, tightened. It should also be borne in mind that the gearbox elements must be inspected and replaced in a timely manner when the first signs of wear are detected. This way you can avoid more serious repairs in the future.

Engine malfunctions can occur both during start-up and during operation. In this case, it is imperative to check the spark plugs. If they are dry, there is a problem with the fuel supply, and if they are wet, the problem is in the engine itself.

One of the most common startup problems is the failure of the ignition system. To eliminate such a malfunction, first of all, you need to inspect the electrodes of the candles, and remove carbon deposits that could have formed on them with emery. After that, the candles are washed with gasoline and dried. Starting problems can also be related to incorrect electrode spacing. In this case, you just need to carefully bend them to the distance specified by the manufacturer.

In addition, ignition problems can be associated with damaged electrical wiring or spark plug insulators. These items are subject to replacement. Also, the lack of starting the engine may be associated with stator defects. Unfortunately, it is impossible to repair this part on your own and it will simply have to be replaced.

More often than not, the engine shows signs of malfunction directly during operation. This is due to the fact that small agricultural machinery is exposed to heavy loads and requires regular inspection and maintenance.

Note: If the walk-behind tractor began to move in jerks or make extraneous noises, it is imperative to turn it off, let the engine cool down, and only then proceed to the inspection.

Common problems in engine operation are:

An independent set of revolutions by the engine indicates that the governor and linkage levers are loose and need to be readjusted.
When you press the throttle lever, the engine does not pick up speed, but, on the contrary, loses power. This indicates overheating of the motor, so the technician must be turned off and wait until it has completely cooled down.
Interruptions in engine operation can be associated with a clogged air filter or muffler. The equipment must be turned off, cooled and the parts inspected to clean and remove blockages.

In addition, engine malfunctions can be associated with malfunctions in the carburetor or insufficient oil in it. In this case, the part must be disassembled, inspected and filled with new oil.

A walk-behind tractor with a diesel engine is more difficult to repair with your own hands than a gasoline one, since such a motor has a more complex design.As a rule, possible malfunctions and ways to eliminate them on your own are described in the instructions, so we will focus only on the most common ones.

Diesel engine malfunctions can be associated with such problems:

Clogged nozzle: the part must be removed, cleaned and reinstalled.
Weak fuel injection pressure you can also adjust it yourself, using the instructions for the technique.
Engine cranks too easily with starter: this indicates insufficient compression in the cylinder. To eliminate the malfunction, tighten all the nuts on the cylinder one by one and replace the gasket on its head. It is also necessary to inspect the piston rings, and wash or replace them if necessary.

Malfunctioning starter motor can also cause malfunctioning of the engine. Most often, there are situations when the screws securing the starter housing to the engine housing are loosened. In this case, the starter cord will not return to its original position. To fix the problem, loosen the screws and adjust the position of the cord so that it easily returns to its original position (Figure 6).

Figure 6. Scheme for starter repair

In addition, malfunctions can be associated with wear on the starter spring. It is impossible to repair it, so the worn out part just needs to be replaced.

If you want to master the practical skills of DIY repair, we recommend watching a video that describes the main causes of equipment malfunction and how to fix them.

My model of the cultivator solo509 does not work, the pneumatic cylinder of the clutch, how does it work schematically, can I somehow repair it? Image - Do-it-yourself caiman cultivator gearbox repair

There is no point in repairing the pneumatic cylinder. It is not collapsible and inexpensive. We have it on sale.

Thank you, I took it off, the first time I see such a cannonstruction.

There, the answer is unclear, it is pulled together with a puller or something else.

If you want a puller, we remove it with our hands + a pry bar. The pulley sits tightly, it's scary to shoot.

How to remove a pulley on a gearbox

Below such a question has already been

Hello, I have a motor cultivator Master Yard Elite 65C2. There was such a problem: it drives forward normally, and when I turn on reverse reverse, it still drives forward when the clutch is engaged. What could be? Is the plastic reverse gear worn out? Previously, there was a problem that he did not go back when the reverse reverse was engaged, but it was eliminated by pulling the cable. Please tell me where to look for the problem.

We fill in EP-0 semi-liquid

If tightening the cable does not help, then disassemble the gearbox. Look for the reason there.

Thank you very much, everything came quickly. Packaged well.

The body is also plastic, but strong, knocked out the reverse gear under load, the splines on the plastic gear were rounded, cut with a jamb so that there was an acute angle on the tooth, the problem disappeared by itself.

Good day! I have a pubert vario 60bc3 walk-behind tractor, the engine is bricks, in short, the downshift works, and the second one is only idle, only the cutters are on the ground, they stop immediately, but the engine is running and it seems like there is no load for it. And the first pulls normally without slipping. It turns out there the clutch is worn out in second gear only? it is not clear somehow.

The Vario walk-behind tractor has a different gearbox. It is necessary to disassemble. Either disassemble it yourself, or take it to the service. Then, if you need a spare part, write to the mail

In the new vario automat box, everything is not so good either. There, the gear shift in the box often jams (straight from the factory, in the unisaw service center only on two copies the box normally works out of 15 pieces presented) due to the fact that the shift fork has two plastic washers - above and below in the box itself. They crumble (any of them, usually the bottom one). I corrected it by self-grinding a similar one from a brass blank.

Garden Technique Center for Machinery and Equipment There are no plastic parts except for 2x plastic washers on the bottom and top of the fork. They are the reason for poor switching.

I have never met a Vario box breakage. Many boxes and gearboxes of walk-behind tractors have jamming when turned on. It is impossible to stick the speed by force, the walk-behind tractor needs to be swung back and forth and turn on again, maybe a tooth falls on a tooth.

Because of this, by the way, the gear shift cables are often torn (1200 rubles) - the most popular spare part in the Unisaw warehouse. And here is a plastic washer for 50 rubles. I ordered from them, they did not have it in stock. They took her from France for two months, and did not wait.
