摘要

The reversible mounted plough has a front chassis, a rear carriage with two wheels, and a rotary plough frame (2). The plough frame (2) is pivot mounted both on the front chassis and on the back carriage (3). On the back carriage (3) or front chassis is a first roller track symmetrical with the transverse centre of the back carriage. On the plough frame (2) is a second roller track acting in conjunction with the first track. The plough frame is joined to the back carriage or front chassis by means of a universal joint which, when in an operating position, is higher than the ends of the first roller track. The first roller track rises from the ends to a peak in the transverse centre.
