PROPULSION SYSTEM FOR SKIDDER

摘要

A skidder having a diesel engine coupled to a multiple gear ratio transmissi on driving a pair of wheel sets for a skidder. The diesel engine is controlled by an operator manipulated foot pedal or hand lever to control the power output and ultimately the maximum skidder ground speed. A controller is provided to pre-select the maximum gear into which the transmission may be placed to ultimately limit the maxim um ground speed of the skidder so that the operator sets the forward speed in a binary fashion by depressing the foot pedal or hand operated device to a maximum output condition.
