Abstract
A control system for controlling a hydraulically operable link mechanism mounted on a working vehicle. The link mechanism includes lift arms, a hydraulic actuator for controlling the lift arms, a first and a second lower links each connected at one end thereof to a working implement, and connecting rods interconnecting the lift arms and the first and second lower links, respectively. The control system includes a first coupling for pivotally connecting the first lower link to one side of a vehicle body, a second coupling for pivotally connecting the second lower link to the other side of the vehicle body, strain gauges provided for the first and second couplings, respectively, and a control device for controlling the actuator based on detection signals received from the strain gauges.
