摘要： A semi-supportable plough apparatus comprises a frame carrying a number of individual plough beams and having a running wheel mounted at its rear end. A universal pivot structure comprising vertical and horizontal pivots is mounted on the frame for pivotally connecting the latter to the three-point system of a tractor. A transversely extending stabilizer rod is disposed in underlying relationship to the lower side of the draw links of a tractor and a spring mechanism interconnects the stabilizer rod and the pivot structure whereby the tendency of the frame to rotate relative to the tractor links about the horizontal pivot is yieldably limited.
