• Speed hold/limiting function allows the machine speed to be limited in 1 km/h or 1 mph steps to conform to site speed restrictions.
• Gearshifts have been significantly improved to maintain direct drive lock-up, and eliminate dropping into converter drive. Reducing the use of torque converter drive helps maintain ground speed and gradeability.
• Variable shift points used based on the operating conditions, which also aid in maintaining ground speed during gear changes on grades.
• Critical gearshifts maintain direct drive lock-up, and eliminate dropping into converter drive. This maintains ground speed during shifts on grades.
• The transmission automatically modifies shift points to best suit operating conditions and performance.
• Retarding levels are automatically reduced on lesser grades in lower gears.

Torque Converter

Large capacity torque converter, configured for off‑highway applications, allows the higher engine power to be transmitted more efficiently to the lower power train.

Engine Compression Brake

Improves retarding response and increases retarding power.

Automatic Traction Control (ATC)

Application of the inter and cross-axle differential locks is ‘on-the-go' and fully automatic. The operator does not have to think about when and where to engage either the inter or cross-axle differential lock. Sensors monitor the machine and wheel speeds, enabling instant response in low traction conditions. Operation is seamless and smooth, eliminating wheel slip for maximum traction and productivity.

Clutches are also automatically disengaged when not required, eliminating any impact on machine maneuverability, such as making a tight turn at the top of a grade.

The ATC system helps reduce tire and driveline abuse, eliminating lost efficiency caused by improper manual operation of the differential clutches, and reducing the cost of premature tire replacement.

All three axles have oscillating a-frames with lateral tie rods, controlling sideways movement of the axle and providing stability. In conjunction with suspension system, it allows the operator to travel at speed over rough terrain and softens impact loads on structures and components.
