A number of agricultural, land reclamation and road construction machinery bearings (wheels, rollers, skis, etc.) are located behind the working bodies and move across the surface generated by their working bodies during the execution of processes. These machines and mechanisms relating to machines and mechanisms with delayed feedback.
We were first investigated by transient planar and spatial models of machines and mechanisms with delayed feedback, a feedback coefficient is greater than one, when exposed to a single step of the relief support surface. When the model coefficient k>1 (this machines and tools to the schemes similar to the bulldozer) transition process from a single push – h0 has the form of a circle with radius r.
