Abstract: Outrigger is longitudinally hinged at inner edge to tractor and at outer edge to ground-supported cutter unit. Outrigger positions cutter as far to side of tractor as tractor wheels or beyond. Outrigger hydraulic cylinder connects outrigger to tractor to swing outrigger up and down, about inner hinge axis, thereby to raise and lower outer hinge axis to adapt cutter to terrain. Cutter hydraulic cylinder connects cutter to tractor at inner hinge axis to swing cutter up and down about outer hinge axis without preventing independent operation of outrigger cylinder. Cutter can be swung up to near vertical position with cutter cylinder and then hook on cutter can be dropped into eye on tractor by lowering outrigger with outrigger cylinder, thereby mechanically locking cutter in elevated position. Cutter is of flail type and is powered from front end of tractor crankshaft through a drive train. Inner end of flail shaft is above inner hinge axis by radial distance from shaft to cutter at end of flail, thereby to maintain inner edge of swath cut by cutter unit fixed at outer edge of outrigger regardless of angle of cutter to horizontal.

Abstract translation: 外伸支架在内边缘纵向铰接到拖拉机，外缘纵向铰接到地面支撑的切割器单元。 越野车将切割机放置在拖拉机侧面的远方，作为拖拉机轮或更远。 支腿液压缸将支腿连接到拖拉机上，以围绕内铰链轴向上和向下摆动外伸支架，从而提升和降低外铰链轴线，使切割机适应地形。 切割机液压缸将切割机连接到内铰链轴上的拖拉机，以绕外铰链轴上下摆动刀具，而不会阻止外伸支架的独立操作。 切割机可以用切割滚筒向上摆动到垂直位置，然后通过将外伸支架悬挂在外伸支架上，从而将切割器机械地锁定在升高的位置上，然后钩在切割器上可以掉入拖拉机的眼睛。 切割机为笛式，由拖拉机曲轴的前端通过传动系提供动力。 连枷轴的内端在内铰链轴的上方，从连杆到切割器在连枷端的径向距离在内，从而通过切割器单元固定在外伸支架的外边缘而切割的条带的内边缘，而与切割器的角度无关。
