Abstract
1354039 Tractor hitches DEERE & CO 13 Oct 1972 [21 Oct 1971] 47428/72 Heading A1P The lower draft links 18 of a tractor have chains 68 which can be connected either to a vertically movable draw bar 47 or to a point close to the pivot axis of the draft links whereby lateral sway of the draft links is limited. When the draw bar 47 is fully raised it is held in position by eccentrics on arms 54 engaging in seatings 64 on the tractor, arms 66 being used to rotate the eccentrics to secure them on the seatings by an over-centre action. A frame 34 extends between the lower links and supports an upper link 36, which includes a ram, by means of springs 38. When connected to the draw bar the chains 68 limit sway of the draft links only in the transport position.
