Abstract

1,178,808. Ploughs. OVERUMS BRUK A.B. 28 Nov., 1968 [28 Nov., 1967], No. 56572/68. Heading A1B. A plough comprises a forward frame portion 2 and a rearward frame portion 3, wherein between the forward frame portion and a tractor (not shown) is a spring 7 so that during upward swinging movement of drawbars A and narrow turns of the tractor-plough unit, the resultant rearward downward swinging movement of the frame about pivot bar 1, which passes through the forward frame portion 2 and drawbars A, is counteracted. The rearward frame 3 is pivotally connected to the forward frame by a pin 4. Wheel 5 has steering rod 6 which is adjustable in length, also the wheel has hydraulic means (not shown) for lifting and lowering synchronously with the drawbars A.
