ABSTRACT:
A second hayrake hitch for use with a tractor is disclosed. The hayrake hitch includes a generally U-shaped main frame of size and height to overfit a forward hayrake which is directly connected to the tractor. The main frame includes a main beam and a wheeled rear support bar which is pivotally interconnected relative to the main beam. A second hayrake is connected to a hitch bar secured to the rear support bar to enable the tractor to simultaneously pull the two hayrakes. A hydraulic cylinder extends between the rear support bar and a leg connected to the main beam and hydraulic lines interconnect the cylinder with the hydraulic coupling of the tractor. By hydraulically functioning the cylinder while the tractor is moving, the rear support bar can be pivoted relative to the axis of the main beam to thereby move the rear hayrake to the right or to the left relative to the front hayrake to simultaneously rake two hay windrows or one large combined windrow.
