Abstract
This paper presents theoretical investigations on the dynamics of working bodies (raising knives, rotary cutter with a horizontal cylinder with spurs) prepared bed combined unit of germinating, ACPG-3 and the dynamics in the work unit to move the field horizontally with constant speed. Be determined, based on physical models, dynamic models for each equivalent of the aggregate body of work and draw on these models is equivalent dynamic model of aggregate, ACPG-3. Also, determine the mathematical models of dynamics and traction unit working parts of germinating bed to move into work, with constant speed, horizontal ground.
Keywords: the combined aggregate, swords loosening, rotary cutter, rollers, dynamics, equivalent dynamic model
