The invention provides a device for regulating the tractive force in the lower linkage system of a tractor lifting gear which serves, for example, to hold a plough. The lower linkages on which the tractive resistance, acting on the plough, is exerted transmit the tractive force to a bending bar, the bending of which is recorded as a measurement of the tractive force. In accordance with the invention the bending bar is rigidly coupled to a bearing frame which is rigidly mounted on the tractor and which absorbs the force acting on the lower linkages while the bending bar is subjected to bending strain. This means that the lower linkages do not exert a force directly on the bending bar, and the bending bar can therefore be supported free from play.
