Abstract
The present invention provides a drive engagement control and speed governor system for a vehicle which is capable of adapting a prior art system, known as a DEC/G system, to different types of vehicles. To accomplish this, the invention provides a valve system having fluid pressure delivery as a function of the magnitude of the control signal fed by an electronic control system. According to this invention, the electronic control system transmits a control signal to the valve system which is only sufficient to eliminate the spinning of a drive wheel on such vehicle or to eliminate exceeding of a predetermined maximum speed by an operator of such vehicle.
