Engine Options
Choose the right engine for you – three fuel efficient Cat® engines are available to suit a wide range of applications.
Frame, Boom and Linkage
Designed for durability. Easy to access greasing points mean a long, trouble free life for the machine. A Z-bar linkage with 152 degrees of coupler rotation delivers powerful breakout forces and fast cycle times.
Powerful Hydraulics
A variable displacement piston pump matched to a high performance flow sharing valve makes multi functioning easy. The load sensing system means excellent fuel economy, as the pump only works when required.
Cab
The cab is designed with the operator in mind with a multi function joystick and a comfortable working environment. The unique “Operator Preferences” feature allows the machine to be tuned to suit individual operators. Options include a heated air suspension seat, large display screen with pre-loaded load charts, rearview camera, reversing sensors and air conditioning.
