Benefits & Features

High Performance

An electronically controlled hydrostatic transmission provides adjustable power to the ground and superb groundspeed control for fast digging cycles and the flexibility to efficiently perform a multitude of tasks along with high, full turn tipping loads and breakout forces, the M Series delivers a solution for all customer applications.

Ease of Operation

State of the art electro-hydraulic system provides low effort, fine control with fast cycle times. The all-in-one joystick helps keep eyes on the work. Machine responsiveness can be adjusted with the push of a button, which allows you to set up the machine exactly the way you want it based on the application.

Comfortable Cab

Low effort, responsive joystick includes Forward/Neutral/Reverse switch, optional diff lock, continuous flow triggers with proportional, third function hydraulics.
Easy access to the cab with ergonomically placed grab rails, steps and large platform.
Superb visibility to the work tool due to the wide windshield and Optimized Z-bar Loader.
Low sound levels.
Optional air conditioning with defrost/demist.
Optional heated, air suspension seat with lumbar and seat back tilt adjustment.

Parallel Lift Loader Linkage

The Cat® optimized Z-bar Loader combines the digging efficiency of a traditional Z-bar with tool carrying capabilities for great performance and versatility.

Parallel lift and high tilt forces throughout the working range help you safely and confidently handle loads with precise control.
Linkage features excellent visibility to the bucket cutting edge and fork tips.
