Tractor automatic deviation called driving linear difference, basically have the following kinds of reasons:
1 wheeled tractor with two drive tire inflation pressure is different, so their power with different radius, if the right wheel gas pressure is higher than the revolver, when left, right round the same turn, right round the stroke is larger than the revolver, the tractor can automatically turn off. Therefore, often with tire pressure gauge to check on both sides of the tire pressure, causes it to conform to the prescribed value and equal.
2 wheeled tractor left, right driving wheel tread wear inconsistent, with different height, or tire tread turning over, so that the dynamic radius of not equal, adhesion is different, also can make the tractor automatic deviation. Therefore, the two drive wheels should be renewed, and pay attention to the installation direction.
3wheeled tractor, a right wheel walking in the furrow, revolver in uncultivated land, both sides attached condition is different, right driving wheel and ditch the adhesion coefficient is smaller, but the right driving wheel attachment coefficient becomes the main influencing factors, therefore, right driving wheel slip ratio is larger, so the tractor automatic right run. If not farmland soil was too soft, the tractor can automatically turn off.
4 wheeled tractor front wheel swing is serious, so the tractor is difficult to go straight, front wheel head is a cause of steering trapezoid and the longitudinal rod ball joint pin clearance is too large, ball joint pin fastening nut loose, toe-in disorders, front wheel bearing clearance is too large, the front wheel hub and spoke plate joint is not good, front wheel steel ring fixed nut, front axle swing shaft and sleeve wear, with the gap is too large, to implement meshing clearance is too large.
5 crawler tractor on both sides of the steering clutch wear inconsistent, while steering clutch slip, on both sides of the steering handle free travel is not as great, or one side of no free travel, steering clutch can not be completely assembled, thereby, the steering clutch to both drive wheel drive torque range, so that both sides caterpillar thrust generated by unequal, lead to crawler tractor automatic deviation.
On both sides of6crawler tractor crawler tension is inconsistent, track length is inconsistent, the guide wheel crank shaft deformation, the two longitudinal beams to the same direction of lateral deformation, also will make the crawler tractor automatic deviation.
7of arable land, the soil with high resistance, reduce the number of supporting plow ploughshare, resulting in partial traction.
