Inverted U=shaped attachment frame for mower - has variable tension compression spring supported against set pin and bottom linkage

摘要

The inverted U-shaped mounting frame is rigidly connected with the support frame at a side mower. At the end away from the mower, it acts with a slide guide at the rear end of the bottom linkage. In the raised, transport position, an arm which extends forwards from the support frame is supported on the underside of the bottom linkage. A compression spring (9) is fitted in the attachment frame (4). One end is supported against a set pin (14) and the other end is supported on the bottom linkage (8) via the right slide guide (13) and coupling point (7).
