Kinematics of twin rotary tiller

Abstract

Kinematics of twin rotary tiller with a big front rotor was investigated. This tiller contains two rotors with horizontal axes one behind another. The twin rotary tiller with L-shaped blades can be used for heavy loamy soil handle. The rear rotor is designed to handle upper soil layer. Theoretical methods and computer model were used to calculate the radius of the rear rotor, the position of the rotor above land surface, rotational rotor speed, tractor forward speed at desired sizes of slice pierсe in the upper layer of soil and at given number of blades on one side of a flange.
