High Performance

With its high full turn tipping loads and breakout forces, the M Series delivers a powerful 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

High visibility cab increases comfort with an available deluxe seat, intuitive controls and settings. Optional soft touch pad contains new electronic functions and settings including Implement Modulation and Hystat Aggressiveness, Ride Control, Return to Dig, Lift Kickout, Engine Speed Control, and Rimpull Control. Optional built-in Machine Security System prevents machine theft.

Cat Optimized Z-bar Loader Linkage

The Cat optimized Z-bar loader linkage combines the digging efficiency of a traditional Z-bar with tool carrier capabilities for great performance and versatility. With parallel lift and high tilt forces throughout the working range you can safely and confidently handle loads with precise control.

Power Train

Heavy duty axles and 100% diff-lock come standard on both the 20 km/h (12 mph) standard speed machine as well as the 35 km/h (22 mph) high speed option. Ride control is also available as an option, for added comfort and load retention when having to travel longer distances.

Versatility

Whether using a horizontal style coupler (HPL-ISO or HPL-A) or the Skid Steer Loader (SSL) style coupler, combined with standard flow or optional high flow hydraulics, the Cat Compact Wheel Loaders can use a large range of work tools including hydro mechanical work tools.

Serviceability

The design of the M Series allows quick and easy servicing. Tilt up engine hood and side service doors give exceptional access to the major components safely from ground level. S·O·SSM oil ports and pressure test points enable easy preventative maintenance.
