Key Features

MAXIMIZE PERFORMANCE

Cat C7.1 engine with increased horsepower maintains maximum performance under load
Strong hydraulic horsepower for efficient implement performance and greater productivity
An increase in swing torque of 19 percent on General Forestry configuration provides added power to move trees, which enables more efficiency and productivity
Heavy lift mode features increased lift capacity to handle larger payloads with improved control
989 L (261 gal) counterweight fuel tank for extended machine operation and maximum uptime
Machine width and track length designed for stability in varied logging applications

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

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

One-piece engine hood design, with two opening angles, allows easy access to engine and cooling compartments
Side-by-side engine and hydraulic coolers are easy to access for cleaning, while reduced cooling fins per inch allows better debris flow-through and reduced clogging potential
