Crawler-mode transmission makes it possible to manoeuvre in really tight spots just using the brake pedal.
The new, integral retarder can achieve up to 3500 Nm of braking torque. It is designed to be a secondary retarder and uses the engine coolant as the braking and cooling medium. The previously required oil/water-cooled heat exchanger is no longer required; neither is the related change of oil for the retarder.
Also new is the clutch, which is effectively wear and maintenance-free.Thanks to the centrally-mounted and pneumatically-operated clutch cylinder design, mechanical parts such as the clutch release fork and lever and the coupling force multiplier are no longer needed.
