The innovative design of the hay accumulators allows it to be fully automatic without the use of hydraulics or electronics. It works using excess energy from the baler plunger to push the small square bales to the top of the front chute. Then as gravity moves the bales downward, the last bale in each row swings a door to open the next row. The last bale in the grab opens the back gate. As the hay accumulator unloads itself, springs and counter weights return all of the gates back to their starting position, ready for another grab in good time before the next bale comes. Zero user intervention required. All you need to do to setup the baler is ensure correct hitch-pin position (centered, 8” behind bale chamber) and loosen the pressure in the bale chamber to compensate for the back pressure caused by pushing the bales up the chute. There is no extra pressure applied to the plunger and the twisting action of the chute does not deform the bales. You can do it all without leaving your tractor seat.
