Reverse feed for round balers
A reverse-feed device for big round balers helps reduce the chance of injury and saves time, according to South Dakota vo-ag instructor J.P. Thelen of Pierre.
Thelen developed the add-on reverser while working on an advanced degree at South Dakota State University. The device can be retrofitted to most pto-driven round balers to reverse the hay pickup and compression rollers, kicking out plug-ups so the operator never has to leave the tractor seat.
The reverser consists of a shuttle-type transmission installed in the main driveline between the tractor pto and the baler gearbox. The add-on transmission was modified from another piece of equipment. The reverser is activated by a rope pull. Sprag clutches installed on the baler ensure that the bale in the chamber doesn't turn only the cornpression rollers and hay pickup.
The prototype reverser was installed on a Vermeer 605 baler but should fit any pto-driven machine. Thelen told FARM SHOW the conversion can be made with about $600 worth of parts and about 20 hrs. work. "Time saved baling due to increased efficiency will easily pay for the unit," he told FARM SHOW.
