ABSTRACT:
The present invention regards a rake trolley with adjustable working widths, suitable for three point hitch finger wheel hay rakes. The trolley includes a transverse frame member. A pair of rake arms are connected to a pair of movable heads or supports, and a raising and lowering assembly is interconnected between the frame member and each rake head. The raising and lowering assembly includes a linkage, with a connector member on each side of the linkage extending between the linkage and one of the rake heads. A hydraulic cylinder assembly is interconnected with the linkage for moving it between a first position in which the rake arms are pivoted to a lowered, or working position, and a second position in which the rake arms are pivoted to a raised, or transport, position. The connector members are adjustable in length, to accommodate connection of the rake heads to varying positions along the length of the frame member.
