DESCRIPTION

The Cat® 906M Compact Wheel Loader delivers high performance with outstanding versatility. On-the-go operator tuned hydraulics and drive train adjust the machine's response to the task at hand. Low sound levels, large spacious cab and intuitive controls keep you working comfortably all day long.

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 electrohydraulic system provides low effort, fine control with fast cycle times. All-in-one joystick helps keep eyes on the work. Operator can adjust machine responsiveness with the push of a button, which allows the operator to set up the machine exactly the way they 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.

Note (1)
Cat cab and Rollover Protective Structures (ROPS) are standard in North America and Europe.
Note (2)
The declared dynamic operator Sound Pressure level per ISO 6396:2008*, when the cab is properly installed and maintained, is 75 dB(A). The labeled sound power level for the CE marked configurations when measured according to the test procedure and conditions specified in 2000/14/EC is 101 dB(A). Optional Low Sound or Blue Angel selection will reduce this to 99 dB(A).
Note (3)
