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.
A soil cultivating machine comprising a frame and an elongated portion of said frame extending transverse to the direction of travel of the machine, a plurality of soil working members being rotatable about upwardly extending axes defined by upwardly extending shafts positioned in a transverse row and journalled in said frame portion, drive means connected to rotate said shafts, a supporting structure being located above said frame portion and comprising at least two transverse spaced apart beams, a front beam located adjacent the front of said frame portion and a rear beam positioned adjacent the rear of said frame portion, an elongated tool bar extending across substantially the entire working width of said row and said bar being positioned at the rear of said soil working members, rearwardly extending supporting means interconnecting said bar with said supporting structure, a part of said supporting means extending to the rear of said tool bar and at least one ground engaging support wheel being connected to said part, means for adjusting the vertical position of said bar with respect to said wheel, said bar together with said supporting means being detachably fastened to the supporting structure of said machine.
