Rotary mower having ground supported frames

摘要

A mower embodies a translatable main frame connectable to a towing vehicle having a power take-off unit connectable to a transmission carried by the main frame. At least one translatable wing frame is hingedly connected to an adjacent side of the main frame and is adapted to pivot selectively to a lower operative position and to an upper inoperative position. Depending cutter carrying shafts are supported for rotation on the main frame and the wing frame and are connected in driving relation with the transmission. An extensible drive shaft is operatively connected at one end to the depending shaft on the wing frame and a clutch operatively connects the other end of the extensible drive shaft to the transmission. An extensible clutch rod operatively connects the wing frame to a clutch actuator to move the clutch to an engaged position while the wing frame is in a lower operative position and to move the clutch to a disengaged position upon movement of the wing frame to an upper inoperative position. The wing frame is movable selectively to the lower operative position and to the upper inoperative position by a power unit.
