ABSTRACT:
A non-binding reel mount for a harvester platform includes added clearance between the sidewalls of a reel mounting bracket and the reel lifting arms. Side bushings are provided between the brackets and the arms at the center of the arms to prevent lateral motion of the brackets relative to the arms but enable twisting or rotation of the brackets relative to the arms. The non-binding reel mount thus enables one lift cylinder to be fully extended without causing binding between the reel mounting brackets and the reel support arms during a cylinder charging operation. The reel mount can be designed to provide the desired amount of vertical adjustment to the reel. In an alternative embodiment, a single bushing is provided at the top of the support arm that extends between the two sidewalls of the mounting bracket and wraps around the upper corners of the support arm to prevent lateral shifting while permitting rotation of the mounting bracket on the support arm.
