M Series Compact Wheel Loaders – A comprehensive range to suit all applications and environments.

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.

Parallel Lift Loader Linkage – Cat Optimized Z-bar Loader delivers enhanced visibility with maximum productivity.

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.

Industry Leading Operator Station – Superior visibility, ergonomics and comfort.

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.

Power Train – Hydrostatic drive adjusts to be faster or smoother for the task.

Intelligent Power Management

The Cat power train is computer controlled which actively monitors engine, operator input and drive train load, adjusting the hystat transmission to keep the machine working at peak efficiency.


The Cat C3.3B turbo engine provides cleaner, quieter operation while delivering superior performance and durability. The engine also features:

  • The Cat C3.3B Tier 4 Final/Stage V uses an active regeneration system which requires no operator interaction under normal conditions.
  • Automatic, electronic, self-priming fuel pump encourages good maintenance practice. At the service interval, simply install a clean, dry filter element and then turn the ignition key to ON.
  • The easily accessible diesel particulate filter has a minimum 3,000 hour cleaning service interval. The on-board monitor will advise when diesel ash cleaning service is needed.
  • Focused on fuel efficiency, significantly reducing owning and operating costs.
  • The Hystat Aggressiveness feature allows the operator to increase the directional shift responsiveness for faster loading cycles, or adjust for finer control for sensitive tasks such as moving heavy pallets.
  • Rimpull Control feature enables the operator to match available tractive power to underfoot conditions, helping reduce tire wear.
  • Creeper Control precisely adjusts the machine ground speed when using work tools such as brooms and snow blowers.
  • Electronic Engine Speed Control feature allows you to maintain constant engine RPM regardless of travel speed.
  • Thus, pairing Creeper Control and Engine Speed Control, the operator can easily control the hydraulic power going to the work tool, while optimizing ground speed for best operation.
  • Three speed ranges ensure maximum controllability for any task.
Axles, Brakes and Inching Function
  • Fully locking front and rear differential axles are optional and can be engaged at full torque on-the-go below 6 km/h (4 mph), with a button on the joystick.
  • The enhanced modulation of the inching function utilizes the first half of brake pedal engagement to hydrostatically decelerate without any wear on the braking system.
  • The brake system includes independent service brakes on the front and rear axles. The parking brake is mechanically activated and released with a hand lever next to the operator’s seat.

Couplers – Making the Compact Wheel Loader even more versatile.

Horizontal Pin Coupler – A

This coupler is an evolution of the existing ISO horizontal pin coupler and thus has the in built durability and robust design that has been in the market place for many years.

This design gives a zero offset coupler from the machine, similar to the HPL-ISO which optimizes the load capacity and breakout forces versus some Aftermarket Equipment Manufacturer solutions that are less integrated.

Horizontal Pin Coupler – ISO

This quick coupler will pick up a range of Cat Compact Wheel Loader work tools. The coupler along with the profiled loader arms have been designed to give maximum visibility to the work tool. A simple joystick function allows for easy engagement and disengagement of the locking pins.

Additional HPL-ISO to SSL converter bracket adds even more versatility to these machines, enabling a wide range of SSL interface attachments to be used.

Skid Steer Loader Coupler

The universal skid steer loader coupler allows the use of many Cat Skid Steer Loader work tools. Using either the standard or high flow hydraulic option, this coupler allows the M Series Compact Wheel Loaders to integrate into a skid steer loader fleet.

Hydraulics – Operator tuned hydraulics matches responsiveness to the task.

Hydraulic System

M Series machines feature a new electro-hydraulic control system, which allows the operator the ability to fine tune the machine based on the application and operator preference.

  • The new electronic joystick operation is finely tuned for smooth operation, yet fast cycle times.
  • The Implement Modulation feature provides three settings for faster, more responsive hydraulics for repetitive tasks like truck loading. Or, this feature can adjust for smoother hydraulics needed with heavy fork loads or more restrictive areas.
  • An electronic Return To Dig feature levels the bucket as the loader comes down after dumping. This speeds cycle times by letting the operator focus on the next dig point rather than setting the bucket position.
  • The third function auxiliary hydraulics can be set for Continuous Flow when using hydro-mechanical work tools.
  • Ride Control is available to smooth the ride, keep the tires in contact with the ground and maximize material retention.

Work Tools – Do more jobs with one machine.

The Right Tool for the Job

An extensive range of work tools and bucket styles are available to make your Cat Compact Wheel Loader one of the most versatile machines on the job site. Cat work tools are designed to get the best out of the machine and deliver excellent value through high productivity and long life.

Work Tools for Cat Horizontal Pin Coupler

The Cat Compact Wheel Loader offers a comprehensive range of buckets to suit any environment and specific customer needs. The buckets have been designed and engineered to endure the high breakout forces of the M Series Compact Wheel Loader.

The Cat fork carriage has been designed to increase visibility to the forks, allowing the operator to work much more efficiently and safely, without compromising durability. Various fork tine lengths are available.

Work Tools for Cat Skid Steer Loader Coupler

This coupler allows the use of a wide range of Cat Skid Steer Loader work tools including many hydro-mechanical work tools such as snow blowers, cold planers, brooms and wheel saws. It is recommended to check the work tool requirements to ensure the machine is configured for optimal performance with features such as High Flow and Return To Dig.

Auxiliary Lines and Connectors

The auxiliary lines and connectors are fitted as standard, meaning the Cat Compact Wheel Loader comes ready to work.

For a complete list of available work tools please consult your local Cat dealer.

Reliability and Durability – Quality within, quality throughout.
