Title: Agricultural machine with detachable and separately usable propelling structure

Abstract: An agricultural machine which comprises a frame carrying a mounting for agricultural implements such as a plow together with a handle for steering and controlling the machine with at least one axle on the frame. Wheels are provided on the axle whereby the frame may be run over the ground and a last part of a kinematic chain is arranged to drive the wheels. Also provided are rotary hoe propelling mechanism including an engine, a clutch and a gearbox which drive a shaft, the clutch gearbox and the shaft form a first part of the kinematic chain and a mounting for the rotary hoe propelling mechanism is arranged so that a second part of the kinematic chain is driven by the first part and will engage with the last part of the kinematic chain so that the engine drives the wheels. The rotary hoe propelling mechanism is readily detachable so that the rotary hoe propelling mechanism is usable separately for rotary hoeing and the rotary hoe propelling mechanism is readily mounted on the frame to complete the agricultural machine.
