Steiger Tractor's Tiger III, ST-450

A new 450 HP four-wheel drive articulated farm tractor has been developed by Steiger Tractor Inc. This paper summarizes the design, development, and testing of this unit along with an overview of the systems. Several frame designs different from production tractors were used along with more operator convenience and comfort ideas in the new wider ROPS cab. The vehicle combines the performance of a high torque rise engine with the advantages of a powershift transmission with torque converter.
