PROPULSION SYSTEM FOR SKIDDER

摘要

A skidder having a diesel engine coupled to a multiple gear ratio transmission 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 maximum 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.
