Benefits and Features

The Cat® C7.1 engine provides cleaner, quieter operation while delivering superior performance and durability through a high torque, low speed design. Caterpillar's exclusive Intelligent Power Management system monitors operator input and power availability to keep the machine working at peak efficiency and provide the operator with greater customization to suit their application.

A choice of Power Modes allows you to choose between maximum fuel efficiency or boosted power along with hydraulic speed.

STANDARD POWER MODE

  • Saves fuel and reduces cab sound levels
  • Biggest gains are seen during load and carry, snow removal and roading applications

PERFORMANCE POWER MODE
  • Enabled at the push of a button (HP+), boosts engine power by up to 10% and engine speed by over 12%
  • Increases hydraulic cycle times and productivity

Lock up and go with fully locking front differential axle that can be engaged on the move at full torque. Maximize your traction with optional Limited Slip Differential on the rear axle to keep you climbing.

OPTIMIZED Z-BAR LINKAGE

The optimized Z-bar linkage combines the digging efficiency of a traditional Z-bar with integrated tool carrier capabilities for great performance and versatility. Visibility to bucket corners and fork tips at ground level remain excellent while sight lines at maximum lift are improved with a Generation III lift arm design. Lift higher and reach further with optional High Lift linkage available on all three models.

QUICK LOADING PERFORMANCE SERIES BUCKETS

Performance Series Buckets deliver up to 10% higher fill factors compared to previous models, better material retention for significant productivity and fuel efficiency improvements. The buckets feature a longer floor to take a bigger bite of the pile, an open throat to heap higher and curved side bars to help with material retention.

A spacious, quiet and comfortable operator environment helps keep you relaxed and productive throughout the day. Experience superior all around visibility with single piece front windshield, redesigned linkage and clean hydraulic lines routing. Seat-mounted controls featuring low effort joystick for lift and tilt functions along with integrated Forward/Neutral/Reverse switch, differential lock trigger and optional third and fourth auxiliary functions.
