Modern walk-behind tractors can operate on metal wheels and with traditional tires, similar to those installed on tractors and cars. The “metal” version is usually used for plowing the ground with a plow and for moving over the terrain. “Pneumatic” is considered more versatile, as it is suitable for all agricultural work (plowing, cleaning, weeding, ridging, etc.) and for transporting goods.

Other advantages of rubber tires include:

  • profitability and convenient control of the walk-behind tractor;
  • a high degree of self-cleaning and studs of a “tractor” tread, which provides reliable traction with the ground.

However, all these advantages of wheels with pneumatic tires will be available only if the owners of the walk-behind tractor carefully read the instructions for use and regularly check the condition of the tires, and also control the pressure in the chambers.

What air pressure is considered optimal? Experts have long answered this question. During plowing, the wheels of the walk-behind tractor should be pumped up to 1.8-2.2 atmospheres, and for transporting goods on a trailer, this parameter is usually slightly lower and should be within 1.5 and 1.8 atmospheres. There are separate requirements for long-term storage of mini equipment, during which the tire pressure should be about 2 atmospheres, and the unit itself should be placed on stops so that the wheels do not touch not the ground.

We have determined the optimal tire pressure in the walk-behind tractor. Now let’s try to figure out what happens to the wheels of the walk-behind tractor if the owner of the unit does not follow the manufacturer’s recommendations. When driving “on the rims”, fuel consumption increases sharply, slippage appears, and the risk of rubber damage increases, especially on the sidewalls, in the form of creases and peeling of the cord. Well, heavy “pumping” of the wheels leads to increased tread wear.

In conclusion, some rules to improve the efficiency of the walk-behind tractor:

  1. It is recommended to install the wheels on the unit exclusively in the direction of the tread (arrow in the marking on the sidewall of the tire) in order to create working conditions with maximum traction with optimal grip on the ground.
  2. When working with loose soil, pumping tires is not recommended. It is best to try to solve the problem of poor grip by adding extra weight.
  3. When working in areas with uneven ground, large wheels should be used to ensure machine stability.
  4. At the end of the work, thoroughly clean the lugs of the tread from dirt, stones and other contaminants to increase the life of the tires. For the same reason, it is recommended to store the walk-behind tractor in a ventilated place with low humidity.

We hope that the information in this article will help owners of walk-behind tractors to know exactly what pressure in the pneumatic wheels should be maintained during the operation of this unit and to understand why it is so important to carefully control this parameter.
