Abstract

A portable tiltable platform includes a trough extending to the peripheral edge for communication with hay being transported to it from a rake pickup which feeds it to an auger and in turn to a compressing roller and then into the inlet end of the trough at the peripheral edge of the platform when the platform is in the horizontal transport position. 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 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 posts are provided which have compression arms extending to the center of the platform which receives hay from the outlet end of the trough. The pressure arms moving arcuately engage the hay to sweep it along the platform top surface causing a stack 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 the 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.
