Abstract
180,610. Rutley, S. F. Oct. 10, 1921. Couplings for tractors.-A laterally adjustable draw-bar attachment for the rear of an agricultural tractor comprises a draw-bar 4 pivoted at 5 to the tractor frame, a transverse guide-bar 3 carried by extensions 1, 2 of the tractor frame and an operating lever 12 adapted to adjust the draw-bar laterally by means of a link 10. The single transverse bar 3 is disposed between the draw-bar 4 and a short bar 7 secured to the draw-bar while double-ended swivelling eye-pieces 9 arranged between the members 4, 7 serve for the attachment in alternative positions of the link 10. A doubleended eye-bolt 11 passes through the operating- lever 12 which is pivoted at 13 and is fixed by engagement with recesses between segmental blocks carried on a sector 17 formed from a single piece of flat bar. In a modification, the drawbar slides between two transverse guide-bars 3.
