ABSTRACT:
A hay stacking machine having a platform for supporting a stack of hay. A radial trough extends from the center to the outer peripheral edge of the platform for accommodating hay being transported to it from a rake pickup. The trough includes a longitudinally extending side wall and a bottom wall which extends laterally to merge with the platform top surface. The bottom wall merges at its forward inner end with a portion of the bottom wall extending upwardly to merge with the platform surface. A portion of the platform surface extends over the vertical wall of the trough and over reciprocating out of phase feed teeth in the bottom wall and vertical wall of the trough. An annular frame extends around the platform and rotates relative thereto. A plurality of upright posts are attached to the annular frame. Compression arms extending to the center of the platform are pivoted on the posts and engage hay located on the platform. The pressure arms moving arcuately engage the hay to sweep it along the platform top surface causing stack of hay to form from the bottom up. The compression arms decrease their pressure on the hay as the arms move upwardly while the total pressure remains substantially constant since the hay increases in weight as it increases in height. The unloading of the platform is accomplished by opening gate sections forming a cage around the stack and tipping the platform rearwardly and downwardly followed by operation of a push-off member which moves from the forward end to the rearward end of the platform.
