    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.

    A bulldozer, like many building, road, agricultural and other machines and mechanisms has a working unit supporting wheels, tracks or skis. All of them have a late feedback in kinematics scheme. In contrast other the bulldozer in kinematics chart has a late feedback with amplification factor of k >1. Thus insignificant change of position of supporting units or shovel, cause a considerable change in the depth of treatment. Number of research works revealed that this transitions period described by an arc, and a circumference.

    A new type of continuously variable transmission with a kinematic chain management is developed. The use of continuously variable transmission in the kinematic chain management in a short reduces the weight and dimensions of the variator. This transmission can be use in variety of machines and vehicles.
