ABSTRACT:
A haymaking machine has at least one, but preferably two, tined raking heads that are driven to rotate about upwardly extending axes from respective mountings. The mountings are connected to the rear of beams that converge forwardly to a right angled junction and a common gear box. Crop passing between the rake heads is thus unobstructed by an overhead frame. A coupling near the junction is connectable to a three point lifting hitch and a pair of spaced apart plates form a pivot connected at one side of the plates adjacent the junction. A retaining element secures the beams in operative positions about the pivot. Each rake head has one, but preferably two, ground supporting cylinders that are positionable around the rake head's axis of rotation. A rear crop guide is pivoted to each rake head near its mounting by a quadralateral linkage that can be set in any one of plurality of guide positions.
