Tractor drawn disc narrow with X=shaped disc roller - has front and rear rollers, forwards swivelable on frame centre girder

摘要

The disk harrow with the disc rollers set in the form of an X has the front (10,12) and the rear disc rollers (11,13) arranged swivellably on the central girder (2) of the harrow frame (1). The folding bearings (14,17) arranged on the girder are installed at such a distance (a) from each other that the disc (22) of the rollers are staggered in the transport position (d) and intermesh. The harrow undercarriage is set behind the rollers, and there is a hoist for coupling of other implements. The rollers are swivelable on centre girder, with an inner joint for adjusting working and transport positions respectively. The rollers abut outer frame parts and can be secured there. ADVANTAGE - Simple conversion from working to transport width.
