  • Control device for position-control of implement coupled to an agricultural vehicle
    Patent number: 4886123
    Abstract: In a device for controlling a slip and a traction force of an implement coupled to a tractor by a hoisting unit, a slip contol system is combined with a traction force control system. The control device includes a drive speed sensor connected to the tractor and an acceleration sensor positioned on the tractor. A measured acceleration value is compared in a comparator circuit with an adjusted output signal of the drive speed sensor, and an actual slip value is determined by integration from an acceleration difference signal. The actual slip value is used for adjusting a control value generated in the traction force control system to control a position of the hoisting unit.
