  • Patent number: 10779482
    Abstract: A sod harvester stacking head can include a base that couples to a stacking head supporting mechanism of a sod harvester and a frame that couples to the base via crankshaft assemblies that are configured to allow the frame to rotate through 360 degrees during each stacking operation. Accordingly, a motor that controls the rotation of the crankshaft assemblies can be driven a single time during each stacking operation thereby enhancing the efficiency of the sod harvester. The crankshaft assemblies can also be configured so that the crankshafts are in a vertical orientation while the stacking head travels in a lateral direction such that the load is centered on the rotational axis of the stacking head. A stacking conveyor could similarly be configured with a base and a frame that are coupled via crankshaft assemblies to thereby allow the stacking conveyor to be lifted using 360 degrees of rotation.
