Development of a 520 kW Track-Type Tractor Configuration 821080

A new configuration was developed for track-type tractors in the 500 kW–550 kW range to meet the market need for productive capabilities greater than those of any existing tractors. This paper identifies the design goals that were established for a tractor of this size; and it explains the major design features, such as modular construction and suspension for track rollers and idlers incorporated in the resultant 522 kW tractor. A review is presented of the test program that was required to assure that the configuration met the design goals.
