ABSTRACT:
A soil cultivating machine has a row of driven rotatable soil working members and a tool bar at the rear thereof to which tools, such as seed drills can be attached. The machine is connectable to a tractor lift and the members are driven via a p.t.o. At least one supporting member is detachably connected to the machine frame and the tool bar for operational support and transport purposes. The supporting member is elongated and extends rearwardly from the frame above the tool bar and to a rear support wheel. The supporting member includes a forward support that is pivoted to a rear arm and a hydraulic assembly bridges the pivot connection. Actuation of the assembly lifts the machine, including any tools on the tool bar so that the entire machine with attachments are supported solely by the tractor lift and the rear wheel or wheels.
