Tired of hydraulic hoses that need to be transferred to the tractor? Perhaps an electrical proportional controller with radio control is something for you? Contact between the trailer and tractor is then made via radio and only one hydraulic hose is needed for the pressure and return from the tractor. No other contact is needed between the controller and the trailer. The controller is available with control via paddles or joysticks. Pictured is radio control with joysticks.
