Operating off the tractor's hydraulics, the Wray Stacker Big-Bale Accumulator fills up with a load of 3x3x8-foot bales stacked three high then automatically unloads them out the back. The implement, which is equipped with a scissor-hoist tilt table on one side and stationary table on the other, works this way: (1) the baler ejects a bale onto the tilt table; (2) the scissor hoist raises the tilt table to a predetermined height; (3) a hydraulic cylinder under the table platform tilts the bale 90 degrees onto the stationary table; (4) the procedure is repeated for the next two bales, with the tilt table rising higher each time; (5) once the three bales are in place, the stationary table's tailgate lowers to the ground and a kick-off arm gently pushes the stack off. A switch located in the tractor cab can override automatic ejection, if the operator desires. The unit can also stack only two bales or simply drop a single bale.
