Abstract: A wheel support arrangement for use on haystacking machines which permits lowering tbe bed of the haystacking machine so that stacks formed can be unloaded, and also so that stacks can be reloaded conveniently for hauling from one place to another if desired. Thus, the haystacking machine is used either as a stacker and unloader, or as a stack mover which can load existing stacks and move them to a different location. The lowering device involves the pivoting of an axle mounting the wheels for the stacker, and includes safety stop members to prevent the wheels from accidently lowering.

Abstract: A feeding control for regulating the feeding of hay or other forage crops into a grinder of the "tub" type wherein a large hopper or tub is used for feeding the forage into a rotating cylinder adjacent the bottom of the tub, and wherein the forage or hay crop is moved across the cylinder for grinding. The feed control comprises a slidable cover plate member that regulates the size of the effective inlet opening to the cylinder to control the amount of forage which can contact the cylinder at any one time.
