Benefits

Application Specific Configuration

INCREASED PAYLOAD
Additional counterweight improves stability without reducing ground clearance or departure angle to maximize performance.

LONG LIFE SAND AND GRAVEL BUCKETS
Performance Series Buckets deliver higher fill factors and better material retention for significant productivity and fuel efficiency improvements. The buckets feature a long floor, open throat, curved side bars and additional serviceable wear plates including corner guards.

PROTECT YOUR POWER TRAIN
Increase your fording depths with optional elevated breathers. Remote mounted high on the machine for the front and rear axles and hydrostatic gear box. Allows settling pond clean out without contamination.

Efficiently Powerful

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.

Sustainability

The Cat® C7.1 engine meets U.S. EPA Tier 4 Final, EU Stage V and Korea Tier 5 emission standards.
Engine Idle Management System (EIMS) helps maximize fuel efficiency and reduce greenhouse gas emissions while maintaining machine performance.
Engine Idle Shutdown Timer reduces fuel burn, greenhouse gas emissions and unnecessary idle time by shutting down the machine after a pre-set idling period.
Performance Series Buckets have rounded side boards, a longer floor and open angle to carry more and load quicker so each pass is the most efficient.
Rimpull Control is a quick way to adjust the torque to the tires for less slipping and tire wear.
Cat® Production Measurement provides real-time payload weighing which help you maximize productivity, reduce fuel burn and greenhouse gas emissions, all while improving job site efficiency and lowering costs.
Extended maintenance intervals not only reduce downtime but decrease the amount of fluid and filters that are replaced over the life of the machine.
Power on Demand, transparent to the operator, provides full-time efficiency and power when you need it.
Tire Pressure Monitoring provides real-time tire pressure information to the operator to help increase tire wear and achieve better fuel efficiency and reduced greenhouse gas emissions.
Intelligent Hystat Transmission helps improves control and reduces fuel consumption and greenhouse gas emissions in load and carry applications.
Variable Displacement Pumps match power to load as application requirements change.
