Abstract
Grid members for supporting a bale of hay within the tub of a tilt-tub bale processor are fixed to the floor of the tiltable tub and extend across an opening in the floor in order to control the feed rate of crop materials toward the chopping and disintegrating rotor. The tub is shiftable to any one of a number of slightly tilted orientations so that bottom reaches of the bale within the tub engage only a selected portion of rotor hammers. If the rotor tends to plug, the tub can be tilted away from the rotor and the grid members supporting the bale simultaneously shift lower reaches of the bale away from the rotor hammers so that the latter are able to clear. In preferred embodiments, a knife extends across the floor opening in transverse relation to the supporting grid members to provide a pinch point for crop materials entering the rotor chamber.
