All Day Comfort
Choose either a canopy or a sealed, pressurised cab with air conditioning, adjustable wrist rests, and a suspension seat option to keep operators productive across full working days.
Easy to Operate
Intuitive Next Generation LCD monitor provides clear machine information at a glance. Advanced touchscreen monitor available as an upgrade. Consistent controls layout shared across the full Cat mini range.
Stick Steer Travel Mode
Cat exclusive — switch from traditional travel levers and pedals to joystick-only machine movement and blade operation. Less fatigue, more precise control in confined spaces.
Big Performance in a Compact Design
35 gpm pump flow and 11,061 lbf bucket breakout force deliver serious 5-tonne class digging capability. Compact radius design maintains tight-access performance despite the increased power output.
Safety on the Job Site
Built from the ground up for operator safety — courtesy work lights, fluorescent retractable seat belt and ROPS-certified canopy and cab structures protect the operator in any situation.
Simple Service for Less Downtime
Daily check points are at ground level through side doors — no tools required. Extended service intervals versus the previous generation reduce total time in the shop.
Lower Operating Costs
Auto idle and auto engine shutdown reduce fuel burn during down time. Load-sensing variable displacement hydraulics optimise flow to match demand, cutting energy waste throughout the work cycle.
Unmatched Dealer Support
