Haymaking machine with two adjustable spinners with tines - has central tedding and side windrowing deliveries

摘要

A beam (1) carries two spinners (2 & 3) and is hitched to a tractor by a frame (4). The spinners are driven by the tractor power take off. The boom is set at right angles to the direction of travel and the spinners rotate so that they converge at the front. They are tilted downwards in the front. The tine trajectories of the two spinners overlap turning, aerating and throwing the hay rearwards. The boom is set at an angle to the direction of travel and the spinners rotate in the same anti-clockwise direction. The right hand spinner is set forward and passes hay back to the left hand spinner which throws the hay against a windrowing board.
