Reaping or haymaking machine - is coupled to tractor by framework hung on vertical axle and has hydraulic rams to raise or lower flanking sections of implements

摘要

The implement can swing laterally left or right on an axle (11) and in addition, the frame (1) is mounted on a semicircular three point yoke (5). This provides the facility for the implement sections to swing about a mathematical axis (P). The frame consists of implement bearings (2) connected to fixed frame (1) by links (4) pivotted at (3) and mounted in such a way that their projections (10) intersect at the mathematical point (P). The implement sections (7) can move down or up as indicated by points (P" and P') and lines (8,9), and they can also be swung up vertically for road transportation. ADVANTAGE - Works equally well over undulating ground.
