New features for the 410-hp D9T Track-Type Tractor include increased operator comfort, safety, and convenience. A low-effort electronic dozer control handle allows one-hand operation of all dozer functions. The Dynamic Inclination Monitor prints readouts of the tractor’s pitch angle and side-to-slide slope. The Enhanced Auto Shift system provides operator-selectable forward and reverse speeds similar to an automatic transmission, while the OK-to-Start system electronically checks powertrain, engine coolant, and engine oil systems.
