PURPOSE:To permit smooth turn without injuring crops by installing a seat in silidable ways in the longitudinal direction and allowing a rear wheel to be floated-up from the ground when a steering wheel is lowered, in the driving control machine for a cultivator, etc. CONSTITUTION:A battery 6, transmission 2, and an engine 1 are arranged in succession from the front on a body frame onto which a driving wheel 7 are axially supported, and a working-machine installation pitch 4 is fixed onto the front edge of the body frame. A steering wheel 3 is fixed through a stay, etc. onto the body frame, and the front edge of a hexagonal pipe frame 10 is pivotally supported onto the lower part of the body frame by a transverse pin 8, and a hexagonal slide frame 11 equipped with a seat 12 at the free edge is inserted into the frame 10. One edge of an actuator 15 is pivotally supported 16A onto said pipe frame 10, and a supporting frame 18 having a rear wheel 19 at one edge is pivotally supported 17 on the free edge side of the actuator 15. |
