<p>MACHINE AND METHOD FOR STACKING HAY: A hay stacking machine having a platform for supporting a stack of hay. The platform has a trough extended from its center to the outer peripheral edge for accommodating hay. A hay feeding mechanism having reciprocating teeth operates to move hay from the outer edge of the platform generally toward the center thereof. One embodiment of the machine has a movable elevator member located in the center of the platform operable to move hay upwardly to build the center of the stack. An annular cage extends around the platform and rotates relative thereto. The cage has a plurality of upright posts carrying compression arms which extend toward the center of the platform. The pressure arms move with the cage and engage the hay located on the platform to sweep it along the platform top surface causing a stack of hay to form from the bottom up. The unloading of the hay stack from the platform is accomplished by opening gate sections of the cage and tipping the platform rearwardly and downwardly. A push-off member moves from the forward end to the rearward end of the platform to slide the hay stack off the platform.</p> |
