Haymaking machine for attachment to tractor - comprises frame mounted on wheels equipped with centrifugal rake which can be raised up transportation

摘要

The haymaking machine has a vertical frame (4) for attachment to the three-point coupling (2, 3) on a tractor (1). Attached to the frame (4) is a chassis frame (12) supported on wheels (15, 16), and which is hinged on pivots (14, 14'). A gyroscopic rake rotates on a vertical axle incorporated in the chassis (12) which can swing to a limited degree on the frame (4). Two independent links (8,8') connect the chassis (12) to the frame (4) by attachment to it at one end (9, 9'), and to hinges (14, 14') at the other end. A hydraulic or pneumatic ram (22) is attached to the chassis (12) at its centre of gravity (24) and to the frame (4) on a transverse horizontal hinge (23), and its function is to raise the machine from a horizontal working position to a near vertical position for transportation. USE/ADVANTAGE - Attaches to the front of a tractor and conforms readily to the ground surface. Easily transportable.
