Abstract
The cylinder (19) is connected across a parallelogram linkage with a cranked upper member (8) and a straight lower member (17), the upper member being attached by a pivot (6) at one end to the chassis (3) and a second pivot (13) at the other end to the tailboard (14). The lower member is attached by a pivot (18) to the tailboard, and at the other end by a pivot (16) to an L shaped arm (5) which is in turn attached by a pivot (4) to the same bracket (3) on the chassis. This L shaped arm (5) is first lowered so that a shoe (5a) at the other end rests on the ground. The tailboard is then raised and lowered by the upper and lower linkage members.
