<p>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.</p> |
