Most horizontal single-cylinder diesel engines are used. The power of the engine is transmitted to the drive train by a V-belt, and the speed of the power is controlled by a clutch. The power is transmitted to the gearbox through the chain transmission box, and the central transmission, final drive, steering mechanism and brakes are all installed in the gearbox. The gearbox adopts gear transmission, and the gears vary from type to type, generally 6+2 gears (that is, 6 forward gears, 2 reverse gears), at least 3+1 gears, and most can reach 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 a jaw clutch or a copper ball clutch.
The control mechanism is installed on the hand frame to control the throttle, speed change, steering, braking and power output. The power is output directly from the power output shaft through gears or directly from the engine. In order to meet the needs of paddy field operations, the walking device is equipped with a variety of iron impellers in addition to tires and a tail wheel. The tail wheel has two types: a transport wheel and a tilling wheel. The former is used to support the weight and assist steering; the latter is used to adjust the tillage depth. The skid can be used for paddy field operations.
