Leveling device for use with reaping-machine threshing-machine to level sides of slopes to harvest e.g. corn, has pivot whose rear position confers high stability in all positions, and Cardan shaft passed through center of reinforcement

摘要

The device has two modules that are intercalated between a beam axle of a reaping-machine threshing-machine and right and left reducers. The modules allow displacement of axis of driving wheels vertically to top or bottom through a pivot, which is placed at rear of a drive shaft of one of the reducers. The pivot provides high amplitude through a jack. Rear position of the pivot confers high stability in all positions. A Cardan drive shaft of the reducer is passed through a center of a tube reinforcement, which is moved in a bean shaped opening on a fixed flange.
