- Air conditioning is standard.
- 12V power receptacle for charging cell phones.
- A reclining air suspension seat with adjustable armrests.
- Storage space for literature and cup holder.
- Low effort joystick controls designed to match the operators natural wrist and arm positions. Consoles can be adjusted independently of the seat for maximum comfort.
- Overhead skylight improves visibility and can be opened to create air flow.
- Upper front windshield opens and easily stores on the roof above the operator with an automatic latching mechanism.
- All functions are fully pilot operated lowering owning and operating costs.
- Pattern control changer is located under the floor mat.
- The compact radius design provides greater versatility and capability to work within confined areas. The radius of the upper body stays close to the width of the undercarriage allowing the operator to concentrate on the work at hand, rather than the tail swing of the machine.
- Cab door is curved and shaped to follow the line of the cab, it slides open taking up less space than a hinged door. When working in tight areas this allows for safer ingress and egress. This design maintains the machines compact dimensions reducing the risk of damage.
- Jobsite flexibility with a reduced risk of damage and less stress for the operator add up to higher rates of productivity.
- Interim Tier 4 turbocharged engine gives higher power and maintains strong performance at high altitude.
- High digging forces give power through even the most compacted ground with smooth control and responsive hydraulics that deliver productivity that our customers demand.
- Load sensing hydraulics optimize the flow of oil for smooth powerful performance and increased fuel economy.
- Automatic engine idle lowers engine revolutions when not in use to conserve fuel and lower environmental noise/emissions.
- Heavy Duty Buckets

- Ditch Cleaning Buckets
- Hydraulic Hammers

- Make comparisons of machines, with estimates of component life, preventative maintenance and cost of production.
- Financing packages are flexible to meet your needs.
- Your Cat dealer can evaluate the cost to repair, rebuild and replace your machine, so you can make the right choice.
- A worldwide computer network enables the dealer parts counter to locate nearly all parts.
