Compared with prior art, the utlity model has following beneficial effect:
(1) the utility model is simple in structure, and is easy to operate, and result of use is good.
(2) the utility model has increased the contact area of wheel and bottom surface by crawler belt is set, and has avoided on paddy field and moist soil farming to sink and has skidded, and also so that the utility model is more stable in the nonirrigated farmland operation, thereby improves the effect of deep ploughing operation.
(3) the utility model is by arranging reductor, become vulgar rotation when making the high speed rotating of diesel engine be delivered to trailing wheel, avoided diesel engine to directly act on wheel and produced the excessive situation of impulsive force, both prevented that therefore farm machinery from damaging, and also guaranteed operating personnel's safety.
(4) the utility model arranges two cover crawler belts, the stability that has improved operation and placed.
(5) reversing speed reducer of the utility model setting can conveniently be regulated its rotation direction, advances to have run into obstacle and can commutate very easily and return when operation, has greatly improved operating characteristics.
(6) the utility model is provided with seat cushion, operating personnel can be sitting in seat cushion and operate when farming, the tail wheel that its below arranges also can support seat cushion well, guarantee operating personnel's safety, the sense tired out that has produced when also having alleviated operation, and then manyly finish faster and better whole farming task.
(7) the utility model also is provided with pedal, makes operating personnel can place foot when rest, feels more comfortable, has improved the comfort level of operation.
(8) double-bladed plough of the utility model setting has two colters, not only improved the farming effect, but also can ditch to the field, the operation such as ridging, shaping, utilize simultaneously angle demodulator and height adjuster to the angle of colter and highly effectively adjust, adapting to different ground condition demands, thereby improve farming efficient.
