Abstract
A track –tractor usually slide down when it is crossing the slope of a hill; this slide is a result of soil’s deformation in contact’s surface between tracks and ground; the deformation is effect of tractor’s weight and moments of this weight on the slope. The slide down make a deviation of track-tractor forward to hill base, Value of deviation depend on tractor’s speed, mechanical properties of soil, loading capacity of plough, slope, size of Contact of surface.
