Work as one with your machine by customizing the controls.

Flexible Power Train

A smooth, stepless electronically controlled hydrostatic transmission provides adjustable power to the ground with excellent groundspeed control and customizable feel.

• Select your Power Train Mode: – Torque Converter (TC) for smooth rollout. – Hystat for aggressive engine braking. – Default mode which blends the best of Hystat and Torque Converter characteristics.

• Reduce tire wear using Rimpull control which enables you to match available tractive power to underfoot conditions.

• Set Directional Shift Response, soft and smooth for material handling applications or sharp for aggressive operation.

Adjustable Electro Hydraulic Controls

Easily customize the hydraulic performance through secondary display to optimize your efficiency.

• Optimize hydraulic modulation with Fine Mode control when working with forks.

• Quicker hydraulic response for fine grading at speed and quick functions through Lift and Tilt response settings.

• Fully adjustable ride control activation speed along with 3rd function auxiliary flow for powering a broom.

Operator Profiles and Coded Start

• The M Series Wheel Loaders remember your personal settings with unique operator codes to make this machine truly yours and keep it secure on the job site.

Efficiently Powerful

Intelligent Power Management

The Caterpillar exclusive Intelligent Power Management system monitors operator input and power availability to keep the machine working at peak efficiency.

Power on Demand

A choice of Power Modes allows you to choose between maximum fuel efficiency or boosted power along with increased hydraulic speed to get your job done faster.

Standard Power Mode

• Saves up to 10% fuel while running at an efficient 1,600 rpm.

• Recommended for load and carry to maximize fuel efficiency.

• Power-by-range logic increases power in speed Range 4 automatically to maximize travel speed and grade climbing performance.

• Reduces cab sound levels down to a whisper quiet 64 dB(A) typical.

Performance Power Mode

• Enabled at the push of a button (HP+)

• Boosts engine power by up to 10% in all speed ranges.

• Boosts engine speed by over 12%.

• Increases hydraulic cycle times and productivity.

Six Cylinders of Efficient Power

The Cat C7.1 ACERT engine provides cleaner, quieter operation while delivering superior performance and durability through a high torque, low speed design. The engine meets Tier 4 Final and Stage IV emission standards with a Clean Emissions Module that is designed to manage itself so you can concentrate on your work.

• No downtime for regeneration with a passive low temperature system that keeps you on the job.

• Fit for Life Diesel Particulate Filter that is designed to exceed the engine overhaul life.

• Extended fluid fill intervals with minimal use of Diesel Exhaust Fluid (DEF) with up to four fuel tank fills per DEF fill.

• Configurable auto idle shut down based on time and ambient temperature to further reduce fuel burn and keep operating costs low.

• Spark arrester performance as standard – Meets the performance requirements of EN 1834-1.2000 (section 6.4.2 Visual Test).

Power to the Ground

Lock up and go with fully locking front differential axles that can be engaged on the move at full torque with the pull of a trigger on the seat mounted joystick. Maximize your traction with optional Limited Slip Differential on the rear axle to keep you climbing.

Independent service brakes on front and rear axles provide robust stopping performance while a push button electronic park brake allows you to safely secure the machine with ease.

Optimized Z-bar Linkage

The Caterpillar patented and optimized Z-bar linkage combines the digging efficiency of a traditional Z-bar with integrated tool carrier capabilities for great performance and versatility.

• Perfect Parallelism functionality available in Fork Mode gives truly predictable performance while high tilt forces throughout the working range help you safely and confidently handle loads with precise control.

• Visibility to bucket corners and fork tips at ground level remain excellent while sight lines at maximum lift are improved with a Generation II lift arm design.

Quick Loading, Performance Series Buckets

Performance Series Sand and Gravel Buckets deliver up to 10% higher fill factors and better material retention for significant productivity and fuel efficiency improvements. The buckets feature a longer floor to take a bigger bite of the pile, an open throat to heap higher and curved side bars to help with material retention. Wear plates on the sides and bottom maximize bucket life in abrasive aggregate rehandling applications.

Smooth and Predictable Multi-Function Performance

M Series machines feature an electro-hydraulic control system that is governed by the Intelligent Power Management system for peak efficiency. The load-sensing, variable flow system senses work demand and adjusts flow and pressure to match the operators request.

• Multi-Function without compromise through Caterpillar's exclusive dedicated hydraulic systems featuring three pumps. – 1st pump for Intelligent Hydrostatic drive – 2nd pump for implements – 3rd pump for steering system

Drive, lift and steer simultaneously with smooth, predictable control. The M Series simply does what you ask it to.

• Programmable in-cab kick-outs are easy to set on the go for tilt, lower and lift. This feature is ideal for applications where the work cycle is repeatable allowing you to quickly return to programmed set points maximizing cutting edge life.

• Fine tune hydro-mechanical performance with fully adjustable 3rd function flow through the secondary display (when equipped) for a perfect marriage between machine and attachments.
