  • Patent number: 4137973
    Abstract: A preferred number of lifter wheel assemblies each have a pair of lifter wheels rotatably carried at one end of a strut which is pivotally mounted at its other end to a clamp unit having a horizontal flange which projects forwardly past the front transverse beam of the main frame of the sugar beet harvester. An elongated rigid member is welded to the underside of each strut and has a flange at its forward end which projects beneath the clamp unit flange. Heavy-duty coil springs normally maintain the flanges together to cause the lifter wheels to be biased into the ground. Each spring individually yields or compresses when the lifter wheels associated therewith ride upwardly over a submerged rock, thereby preventing breakage of any of the components constituting the lifter wheel assembly.
