摘要 |
The tractor mounted plough (12) with a three point mounting, has the tractive force transmitted through two bars (16) which are attached to opposite ends of a transverse shaft (28). The force on this shaft causes it to deflect elastically and this deflection is used to control a hydraulic circuit. This hydraulic circuit actuates a hydraulic cylinder which raises or lowers the plough (12) in order to maintain a constant force in the bars. The magnitude of the towing force can be adjusted as required and is indicated by an instrument (48) mounted on the tractor (10). |
