<p>1,086,811. Agricultural implements. J. A. BRAUN. April 14, 1965 [Aug. 21, 1964], No. 16000/65. Heading A1B. A reversible plough comprises a rotatable shaft formed in two portions 3, 6 pivoted together by means of a pin 5, a pawl 9 being provided so that the two shafts can be locked in an angular position. As shown the pawl 9 abuts against a face 10 and drops by gravity as the plough is rotated. Screws mounted on the shaft 6 limit the pivotal movement of the shaft 6. The shaft 3 is rotatably mounted in a frame 1 which is attachable to a tractor three point linkage.</p> |
