Abstract

1,141,011. Rotary-scythe mowers. WEBB LAWNMOWERS Ltd. 19 April, 1966 [20 Jan., 1965], No. 2409/65. Heading A1F. In a rotary-scythe mower, wherein the rear rollers (15) are motor-driven, the drive from the motor (12) is taken through a clutch and an endless belt or chain (27), to one of a pair of co-axial rear-rollers mounted on the free ends of arms (17, 18) pivoted about an axis parallel to that of the driving pulley (21) or sprocket of the power-drive, the arms being connected to pivoted arms carrying the front wheels of the mower so that simultaneous heightadjustment of the front and rear of the mower may be effected without interrupting the drive. The arms (36, 17, 18) carrying the front wheels and rear rollers are interconnected by links (38) and jointly connected to a common adjusting mechanism (49) on the mower-frame. The drive includes a cable-operated dog-clutch (23) and a belt-drive 27 passing around jockeypulleys (28, 29) which maintain constant belt-tension in all positions of adjustment. In a modification (Figs. 4 and 5, not shown) the dog-clutch is omitted and the drive is controlled by the jockey-pulleys which are combined into a single cable-adjustable unit as described in Specification 1,060,531. In this modification, the drive-casing constitutes one roller-carrying arm, the axis of pivoting being co-incident with the axis of the driving pulley.
