Powertrain
Transmission . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . automatic dual-path, hydrostatic drive; load-sensing feature automatically adjusts speed and power to match changing
load conditions; each individual track is powered by a variable-displacement pump and motor combination; speed-in-
grip with fingertip speed control; infinite speed control; decelerator pedal controls ground speed to stop; dealer selectable
transmission operating parameters; transmission diagnostic test ports

Service Brakes . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . hydrostatic (dynamic) braking stops the machine whenever the direction/steering control lever is moved to neutral or
whenever the combined decelerator/brake pedal is fully depressed
Parking Brakes . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . exclusive park brake feature engages wet, multiple-disc brakes whenever the engine stops, the combined decelerator/brake
pedal is fully depressed, the park lock lever is placed in the park position, the emergency travel stop button is depressed
on the dash, the F-N-R control is in the neutral position for more than 7 seconds, or machine motion is sensed with F-N-R
in neutral position; machine cannot be driven with brake applied, reducing wear-out or need for adjustment
