Abstract: A machine for stacking hay bales emerging from a hay baler in pyramidal stacks of six bales, has a supporting bed for receiving bales from a drop table. The bed is provided with a side panel and a pair of separator panels for separating rows of bales in the stack, the dividers being tiltable for orienting the bales into a pyramidal stack. The machine is mounted on wheels for towing, with the bed being pivotable from a substantially level position wherein the bales are collected, to a rearwardly dropped position for discharge of the bales onto a field in a pyramidal stack. Improved discharge of pyramidal stacks is achieved by orienting the separator panels at an oblique angle relative to the line of travel of the machine whereby slippage of the bales from between the panels is facilitated.

Abstract: A skid for stacking hay bales discharged from a hay baler, suitable to be towed therebehind, having a platform near the front for the bale stacker to stand on, having at least four bale supporting arms extending rearwardly from the platform adapted to support the hay bales preferrably in a pyramidal stack of six bales in a stable, rain-shedding position, in which the arms are arranged so that when the bales are stacked thereon, the center of gravity of each bale will be located toward the tall side of the stack and method of curing hay by stacking bales, even if moist, in pyramidal stack with the described orientation.

Abstract: A tiltable device for forming weather-proof stacks of hay bales which in the preferred embodiment contains thirty bales per stack comprising a tiltable bed of generally "L" shaped cross-section carried on an axle and adapted to be towed behind a hay baler, the forward legs portion of the bed providing a platform oriented somewhat greater than 90.degree., the device being equipped with hydraulic means to tilt the same and a side rail situated to enable a bale stacking person to ride with the device as it tilts back to deposit a stack of bales.
