Abstract

A power train with an auxiliary creeper drive system is disclosed which includes an engine, a primary transmission having an output shaft selectively driven by the engine, an auxiliary transmission selectively driven by the engine and operatively associated with the output shaft for driving the output shaft at a creeping rate of speed, and a clutch control arrangement for automatically disconnecting the engine from driving engagement with the output shaft when the auxiliary transmission is drivingly coupled thereto. Such auxiliary creeper drive system is particularly adaptable to the transmission of a fork lift truck.
