ABSTRACT:
A rotatable wheel on a mobile frame carries radially extending pairs of movable, opposed crop-gripping arms which are spring-loaded toward each other. Brackets on each face of the wheel pivotably secure the arms. A roller on each arm moves onto and out of engagement with a cam on the frame with each rotation of the wheel, opening and closing the arms. Preferably the brackets, springs and rollers have quickly defeasible attachment hardward for ease in replacing worn parts, like a readily accessible removable pin securing each arm spring in a cavity in the arm, and rollers having shafts with indents in which a spring-loaded lock removably lodges. In one embodiment a lone threaded member secures each bracket and also affords a base locator for the arm spring. A bracket is removable with arms still attached for ease in maintenance with access to the threaded member through the spring cavity.
