The improved 410-hp D9T emphasizes comfort and safety with features like one-hand dozer control and forward-and-reverse shifting similar to automatic transmission. In-cab sound levels have been decreased from 79 to 77 decibels. An on-board monitor provides the machine's pitch angle and side-to-side slope; the power train and hydraulic system automatically lock out when the operator leaves or enters the cab to avert unintentional machine movement. Options include automatic ripper control and load adjustment as well as blade-pitch presets. OK-to-Start electronically checks powertrain and engine coolant and oil systems. The unit's information management system works with cellular and satellite networks to monitor working conditions in real time and provide operations history for off-board analysis. Engine: Cat 410-hp C18. Operating weight: 110,000 lbs.
