Operator Station
Superior comfort keeps you productive, all day long.

Operator Station

Cab Comfort
Spacious, comfortable cab with increased floor space helps you stay productive. Canopy, cab with heat or cab with heat and air conditioning are available. All cabs are pre-wired, making it easy to install future options. A backlit LED display provides system information and is conveniently located in the operator’s line of sight. Right side window opens fully for better ventilation or communication with workers.

Low Effort Controls
Pilot hydraulics for implement control and use with Cat Work Tools keep operator fatigue low. No linkage to adjust or wear ensures consistent control over the life of the machine. The multi functional joystick contains a 3-position Forward/Neutral/Reverse switch, an easy to control third function auxiliary hydraulics switch, and (when equipped) optional bucket positioner (return to dig) switch.

Excellent Visibility
The loader arms have been designed with visibility to the work tool in mind. Wide cab glass area and sloping rear hood provide both a 360 degree panorama and visibility within a few feet of the machine. This makes for safer operation and reduces machine damage caused by collision with unseen obstacles.

Power Train
Designed for power, durability and performance.

Power Train

The MHI S4Q2 Turbo engine meets EPA Interim Tier 4 emissions requirements and delivers superior power to help you get more done.

Rear axle oscillation helps assure four wheel ground contact for optimum traction and stability. Heavy duty axles with outboard planetary reduction gears are built for durable performance. Optional differential lock is available in the front axle only or both axles and can be easily engaged by a foot switch to the left of the steering column to increase tractive effort in poor underfoot conditions.

Power Train
Two-speed closed loop hydrostatic transmission delivers smooth transition from full rimpull to runout. Precise inching control and smooth acceleration and deceleration minimize operator fatigue. Optional speed (creeper) control and hand throttle are also offered.

Ride Control
The optional Ride Control System further enhances the already smooth road handling of the machine, resulting in increased operator comfort and higher productivity. It is suited for extreme applications where operators need to maintain bucket material load or carry a heavy work tool and have a smooth ride.

Built for strength.


Z-Bar Design
The high performance Z-bar loader design is built for strength, visibility and versatile attachment usage. The Z-bar linkage gives the operator a clear view to the work tool and excellent dump clearance while maintaining good cycle times.

Work Tools
Do more jobs with one machine with Cat Work Tools.

Work Tools

The Right Tool for the Job
Increase the machine's versatility with the wide range of Cat buckets, forks and hydraulically powered work tools. Work tools can be changed quickly and easily with the machine's quick coupler system. Available work tools include:
  • Buckets and Forks
  • Augers
  • Blades (Angle/Dozer)
  • Brooms
  • Cold Planers
  • Grapple Buckets, Forks and Rakes
  • Landscape Rakes and Tillers
  • Material Handling Arm

Consult your Cat dealer for a complete list.

Skid Steer Loader Style Coupler
The universal skid steer loader style coupler allows the use of many Cat Skid Steer, Multi Terrain and Compact Track Loader hydromechanical work tools. Standard flow auxiliary lines and connectors are optional equipment.

Additional Options to Increase Productivity
The following options further increase your productivity:
  • Return to dig work tool positioner automatically returns the bucket to level position after dumping.
  • Auxiliary hydraulic lines and fittings for a 3rd hydraulic function when more than general bucket and fork work is required, such as a broom.
  • Work tool wiring harness for fourth hydraulic function such as broom angling.
  • Speed control (creeper) provides variable control of ground speed while maintaining optimal hydromechanical work tool speed.
  • Hand throttle control provides infinitely variable means of fixing engine speed, ideal for steady operation of hydromechanical work tools.

Easy access and minimal maintenance requirements reduce downtime.


Convenient Service Features
  • Easy to lift engine hood provides easy access to all major components and service points from ground level.
  • S•O•S valve is conveniently located in the engine bay for analyzing hydraulic system cleanliness and pressure taps for service analysis, prolonging machine life.
  • Two stage air cleaner with primary and secondary element and a visual restriction indicator improves service life.
  • Auxiliary fuses, relays and other electrical service points are all located together behind a locked door for ease of servicing.
  • Spin-on engine and hydraulic oil filters and fuel filter with water separator are vertically mounted for easier servicing.
  • Heavy-duty wiring increases electrical durability and is multicolored to ease diagnosis and fault finding. Water resistant sealed connectors prevent dust and moisture from interfering with the electronics.
  • Wheels and tires are mounted on studs rather than secured with bolts for easier wheel removal/installation.
