Abstract:
A harvesting platform comprising:a frame having laterally spaced ends;a reel support arm pivotally mounted to the frame at each end thereof, the reel support arms being rectangular in section having top, side and bottom surfaces;a hydraulic lifting cylinder between each reel support arm and the frame, including a controlling cylinder lifting one reel support arm and a controlled cylinder lifting the other reel support arm whereby during initial filling of the cylinders with fluid, the controlling cylinder is first filled and extended before the controlled cylinder is filled and extended lifting one of the reel support arms before the other reel support arm is lifted;a reel mounting bracket slidably carried by each reel support arm, the reel mounting brackets each having a top wall and two sidewalls wrapped around the top and side surfaces of the respective reel support arm, the sidewalls being spaced from the side surfaces of the reel support arms to enable rotation of the reel mounting brackets relative to the reel support arms;a reel mounted on the reel mounting brackets and spanning between the reel support arms; andat least one bushing between each mounting bracket and each support arm and coupled to the respective mounting bracket to move therewith, the at least one bushing facilitating sliding motion of the mounting brackets on the support arms and preventing lateral shifting of the mounting brackets on the support arms while the clearance between the support arms and the mounting brackets permits rotation of the mounting brackets relative to the support arms.
