<p>Linkage for mounting a harvesting implement on the front end of a power driven vehicle to permit limited independent movements of at least a portion of the implement relative to the vehicle. A plurality of support arms have rear ends connected to the frame of the vehicle and front ends of all but one thereof pivotally connected to the implement, cooperating with means for moving the arms in directions to raise and lower the implement. A connector has spaced portions connected to the implement and to the front end of said one of the arms to provide for compound pivotal and limited generally forward and rearward swinging movements of said one arm and implement relative to each other, so that one end portion of the implement may partake of limited generally vertical floating movement relative to the other end portion thereof.</p> |
