The horizontal single cylinder diesel engine is mostly used in the two wheel walk behind tracker. The power of the engine is transmitted from the V-belt to the transmission system, and the speed of the power is controlled by the clutch. The power is transmitted through the chain.

The central drive, final drive, steering mechanism and brake are all installed in the transmission. The gearbox adopts gear transmission, and the transmission gears vary randomly, generally 6 + 2 gears (i.e. 6 forward gears and 2 backward gears), at least 3 + 1 gears, and at most 12 + 6 gears. The power after the speed change is transmitted to the driving wheels on both sides by the central transmission and the final transmission. The steering mechanism adopts jaw clutch or copper ball clutch.

In order to improve the working conditions of the driver, the walking tractor made in China is equipped with 1-2 supporting wheels and seats to become a riding tractor;

two wheel walk behind tractor. Ctor walking tractor is also known as wheeled walking tractor, which is characterized by no driving wheel, but a rotary ctor is installed on the driving shaft, which not only ctes the soil, but also can walk forward.

Walking tractor is generally composed of frame, power unit, transmission system, walking device, steering system, brake and control mechanism.

The two wheel walk behind tracker can be divided into drive type, traction type and dual-purpose type according to operation performance. The driving type is mainly equipped with rotary ctor, so it is also called power ctor;

15HP walk behind tractor, traction type, mainly supporting traction type farm tools; The dual-purpose type can be used for rotary tiller operation (see Figure), tractor operation or trailer transportation.

Two wheel walk behind tracker can be divided into wheel type, crawler type and plough type according to the walking device. Wheeled walking tractor can be divided into single wheel and double wheel according to the number of walking wheels.
