MOVE MORE WITH LESS FUEL
- Engine, hydraulics, and work tool integration are optimized to minimize power losses and increase overall machine efficiency
- Steady state high idle speed and U.S. EPA Tier 4 Final technology reduce fuel consumption
- Larger hydraulic pumps allow engine to operate at lower rpms with increased performance to maximize efficiency
- Component layout and back-to-back main hydraulic control valve reduce oil flow restrictions and aid in greater fuel economy
- Powerful, multi-functioning hydraulics, combined with strong machine performance ensure work tools function quickly and smoothly to complete work faster
OPTIONS TO MEET YOUR NEEDS
- Boom arrangements and hydraulic systems for specific applications enable more effective road building, loading, processing, shoveling, or millyard stacking
- New track options meet shovel logging and low ground pressure application requirements
- Purpose built processor cab option that includes 19 mm (0.75 in) front windows
HEAVY DUTY CONSTRUCTION
- Variable pitch, reversing cooling fan maintains optimum fluid temperature in heavy duty forestry applications
- Cooling capability increased 12 percent for trouble-free operation
- Purpose built upper frame, high-wide carbody, robust linkage configurations, and heavy-duty enclosures are reinforced with thick doubler plates, extra gussets, and other reinforcements for structural integrity in severe applications
- Large, 216 mm (8.5 in) pitch (336 HEX), grease lubricated tracks, provide excellent life in variable forestry working conditions
- Validated and proven excavator technologies ensure overall machine reliability
SAVE ON SERVICE AND MAINTENANCE
