Electronic/Hydraulic Hitch Control for Agricultural Tractors

An electronic/hydraulic control of tractor hitch systems has been developed which makes it possible to improve control quality, increase design flexibility, and ease the operator's duties. This is accomplished by making use of the advantages that electronics brings through:

• -
  Simple measurement of displacements and forces
• -
  Avoidance of friction and hysteresis
• -
  Easy transmission of electrical signals
• -
  Simple mixing of several signals
• -
  High amplification of signals

This paper describes the components and function of the system.
