Title:
ADVANCE-TILLAGE TYPE WALKING TRACTOR
Document Type and Number:
Japanese Patent JP2540097
Kind Code:
B2
Abstract:
PURPOSE: To level the field surface simultaneously with tillage by making it unnecessary to operate a handle for controlling the depth of plowing up and down and saving the labor.
CONSTITUTION: Simultaneously with plowing rotation of a tillage rotor 4, a cage rotor 7 set at the rear part of the machine body is driven to be rotated at a constant very low speed. The machine body 1 is moved forward by the cage rotor 7 at a constant very low speed. Since the difference (slippage of tillage rotor 4) between the rotational peripheral speed of the tillage rotor 4 and the advancing speed of the machine body 1 is constant, the depth of plowing of the tillage rotor 4 is, therefore, kept constant. The field is finished level by a leveling performance of the cage rotor.
