Abstract

A spreader of a combine for conveying crop residue rearwardly from a rotor assembly includes a frame coupled to the combine and has a top portion adapted to receive a portion of crop residue during a harvesting operation. An impellor includes one or more blades for rotatably conveying crop residue rearwardly, and an actuator is controllably moved between an extended position and a retracted position. The actuator is pivotally coupled to the combine. A linkage assembly is pivotally coupled to the actuator at one end and to the frame at another end. The spreader is disposable in a first position when the actuator is in the extended position, and the spreader is disposable in a second position when the actuator is in the retracted position. A movement from the extended position to the retracted position induces pivotal movement of the spreader from the first position to the second position.
