Abstract
A chop mechanism for a sod harvester can include a motor for rotating a cam to lift a chop frame. The cam can include a ready position in which it remains until a chopping action is started. The cam can be rotated from the ready position to a drop position in which the cam no longer supports a follower mounted to the chop frame. After the cam reaches the drop position, the rotation of the cam can be stopped to position the cam in a safe position to prevent the follower from striking the cam as the chop frame descends. Then, rotation of the cam can be resumed to return the cam to the ready position to await the next chopping action. The rotation of the cam from the ready position to the safe position and from the safe position to the ready position can be performed at different rates.
