How Are The Tiller Valves Adjusted?

Tiller has long been known as a means for plowing the earth. For normal operation of the device, tiller valves must be adjusted, which should be carried out at least once a year. This unit greatly simplifies the work of man. With different attachments, he can perform almost all agricultural work. It is used as a vehicle for the transport of goods. Yes, and he can deliver himself over considerable distances on his own.

Tiller and it’s arrangement.

Maintenance is a must-have element for tiller care. It includes the adjustment of some important components that are responsible for the characteristics of the unit. These include valves and carburetor. Their serviceability fully affects the operation of the engine. In case of their malfunction, the transmission and the entire undercarriage of the machine together with the controls will malfunction. To maintain the unit in its normal state, it is necessary to have a good idea of ​​its structure.

So, tiller includes:

  • engine;
  • transmission;
  • chassis;
  • control system;
  • supply system.

Each individual tiller has its own equipment. The engine on them is used two-stroke or four-stroke. On nutrition, they can be diesel or gasoline. Currently, units with four-stroke engines are most commonly produced. They have higher technical characteristics. On large-sized machines are usually installed diesel engines. The rest of the tillers are equipped with gasoline engines.

The torque from the engine is transmitted to the wheels of the car through the transmission. It includes:

  • gearbox;
  • gearbox;
  • clutch;
  • differential (not in every model).

Chassis unit consists of wheels. They are pneumatic and metal. Mounted wheels on the frame along with the rest of the unit.

On the arms and around them are parts of the control system. This is a clutch lever, various levers and buttons to change the direction of movement, to switch speeds. Here is the engine stop button.
The power system consists of a fuel tank, carburetor, fuel supply pipes. The main part is the carburetor. It performs the function of a mixer. This mixer mixes gasoline with air and feeds this mixture into the engine cylinders.

In turn, the carburetor consists of smaller parts:

  • float chamber;
  • diffuser;
  • dampers;
  • spray;
  • mixing chamber;
  • other details.

Different models of tillers have their own carburetors, which are regulated in various ways.

Adjustment of valves

To adjust the valves on tillerx you need to prepare the tools:

  • spanners;
  • screwdrivers;
  • probe or blade for shaving.

Some types of engines may require other additional tools. Adjusting the valves means setting optimal valve gaps for tiller engines. The instructions for the unit size of the gap is specified. The device of engines on each model of the unit is different.

But in general, the sequence of actions is as follows:

  • the engine cover is removed;
  • valve cover is removed;
  • adjustment is made;
  • set valve cover;
  • set the casing.

The valve is easy to detect under the valve cover. Check the size of the gap probe. Most often the intake valve clearance is 0.15 mm, exhaust. 0.2 mm. With proper clearance, the probe fits freely under the valve. If so, then everything is fine. To adjust, loosen the nuts and re-insert the dipstick. Adjust the clearance, tighten the nut. Check clearances again. With normal results, install the valve cover and cover.

Before adjustment, it is recommended to let the engine run, then cool it down. Somewhat different adjustment valves on the tiller brand Agro.

  • warm up and then cool the engine a little;
  • remove the oil bath from the air filter;
  • remove the flywheel housing;
  • mark “0” on the flywheel combined with the mark on the cylinder;
  • the valve cover is removed;
  • clearances are checked;
  • gaps are regulated;
  • tighten all the nuts;
  • the cover and casing are installed in their places.

Approximately the same pattern is used for adjustment on Patriot and Agros tillerx.

For Cascade, you need to do this:

  • remove the cover;
  • remove the valve cover;
  • turn the flywheel to preload the intake valve;
  • measure and adjust valves;
  • put the cover with the casing in place.

The same method can be used when adjusting the valves on the Ural and Centaur units.


Tiller is a real helper for land owners.
It can perform all the necessary work in the garden and the garden. With the help of a plow and a cultivator, he plows and cultivates the site. After hanging on it of other equipment, the unit mows the grass, will transport goods.
The gasoline or diesel engine has enough power for such operations. For proper operation, you need to configure all the nodes and mechanisms of this device. How to adjust the valves on the engine, we have considered. The rest is indicated in the instructions for use.
