Front fixing of attachments to tractor - uses L-shaped frame pivoted at corner and raised by hydraulically operated pivot arm

摘要

The frame is fixed to the front of the tractor (1) by a pivot (2) and has two main side rails (4). These hold a subframe, also having side rails (8) and telescopically adjustable over the attachment. A wheel (15) is at the front and a three point fixing (13) supports the attachment. An upper pivot (22) on the tractor holds a lever and rod (21), its other end (20) on a vertical bar (19) pivoting (18) on the subframe and holding the front wheel pivot (14). Hydraulic cylinders (24) are mounted on the tractor and operate the pivot arm (7) on the main side rails to raise the subframe and elevate the attachment.
