Avoid the formation of plough bottom in dry land by dragging, so as to preserve moisture and prevent drought; The hard bottom layer of paddy field shall be prevented from being damaged to ensure the normal cultivation of paddy field; The specific ground pressure of wheel trailer is 3 times that of shoe trailer. The test shows that the emergence rate of cultivated land after wheel trailer compaction is only 30% - 40%, while the emergence rate after shoe trailer compaction can still reach 80% - 90%; The wheel rut of wheel trailer in paddy field even affects the transplanting and harvesting, and even causes the mud feet to deepen and cannot be cultivated.

2. Large traction force, obvious advantages of deep turning and loading operation

The traction force of wheeled tractor with the same weight is 1.4-1.8 times that of wheeled tractor. In terms of traction efficiency, the large traction efficiency of wheeled tractor Zui is 55-65%, and that of crawler tractor can reach 70-80%. That is to say, for tractors with the same horsepower, the effective power of wheeled tractor engine is 15% more than that of wheeled tractor.

3. Operation efficiency and half a kilo of wheel tractor

Tractors are used for farmland operations. The speed of rotary tillage is generally 5-6km/h, the speed of ploughing is generally 7-9km/h, and the speed of harrowing is generally 10-12km/h. The plowing speed of the tractor is the same as that of the wheel tractor. The tractor tractor is not slower than the wheel tractor in plowing, harrowing, sowing and other farmland operations, and the traction advantage is obvious.

4. Super trafficability and climbing ability

Crawler tractors have low center of gravity, large adhesion coefficient, good slope stability against overturning and sliding, small turning radius mobility, strong off-road climbing ability and other characteristics. They are more adaptable to farmland and terrace operations in mountainous and hilly areas than wheel trailers, especially when equipped with rubber tracks, they belong to all terrain operating machinery.
