Abstract

A reverser which, in a preferred embodiment, has a hydraulic cylinder supported by a chopper baler frame. The opposite end of the hydraulic cylinder is attached to the reverser driver. When activated by hydraulics on a tractor, the hydraulics will extend the cylinder, causing the sprockets to be disengaged. Further extension of the cylinder will cause the reverser driver to engage the reverser sprocket and turn the rotor backwards slightly. After full extension, the cylinder will then be retracted. This process can be repeated a couple of times in order to remove the blockage. The reverser enables the operator to restore the baler to its working condition from the tractor seat. Being able to disengage the rotor from the rest of the machine enables the bale to be wrapped if a major blockage occurs. Also a controlled reversing motion is beneficial, so over-reversing does not occur.
