Abstract
892,479. Agricultural implements. THIEME, C. Aug. 21, 1959 [Aug. 21, 1958], No. 28591/59. Class 6(1). A reversible plough is provided with a frame 1 carrying a pair of rotatable shares, the frame being moved relative to the tractor towards the side to be ploughed as the shares are rotated. A beam 14 is articulated to the tractor coupling means 17 and to the frame 1 by means of a pin 15 and comprises two girders 14 which are moved by a lever 9 pivoted on a pin 12 and operated by an adjustable crank 6 on the rotatable shaft 4 carrying the shares. The shaft 4 is rotated by a handle 23 when the frame 1 is raised clear of the ground.
