Power and reliability

The Cat C13 engine with ACERT™ Technology gives you the performance to maintain consistent grading speeds for maximum productivity. Superior torque and lugging capability pulls through sudden, short-term load increases. ACERT Technology lowers combustion chamber temperatures and optimizes fuel combustion to generate more work output for your fuel cost. Variable Horsepower (VHP) is standard, delivering an additional 3.73 kW (5 hp) in forward gears 1-4 and reverse gears 1-3. This balances traction, speed and horsepower to optimize rimpull and conserves fuel. VHP Plus is optional, giving you an additional 3.73 kW (5 hp) in gears 1-8 for more power at higher speeds.

Hydraulic Demand Fan

The hydraulic demand fan automatically adjusts fan speed to meet engine cooling requirements. When demand is reduced, you benefit from more power to the ground and improved fuel efficiency.

Compression Brake

The standard three-phase compression brake enables higher travel speeds downhill, while reducing wear on brake components. This improves overall productivity and lowers your maintenance costs.

Ether Starting Aid

A standard ether starting aid helps cold-weather startups in extreme temperatures.

Engine Idle Shutdown Timer

This standard feature can be software-enabled by your Cat dealer to shut down the engine after a set period of time to save you fuel and help reduce emissions.

Power Train

Maximum power to the ground

We designed the 16M to give you efficiency and longevity in your most demanding applications.

  • Optional Automatic Differential Lock unlocks the differential during a turn and re-locks when straight for easier operation and improved power train protection.
  • Full Electronic Clutch Pressure Control (ECPC) system optimizes inching modulation for smooth shifts and directional changes, reducing stress on gears.
  • Standard Programmable Autoshift simplifies operation by allowing the operator to program the transmission to shift at optimal points to match your application.
  • Power Shift Countershaft Transmission is matched to the Cat engine to maximize power to the ground.
  • Eight forward and six reverse gears are specifically designed to give you a wide operating range for maximum productivity in all earthmoving applications.
  • Engine Over-Speed Protection prevents downshifting until an acceptable safe travel speed has been established.

Front and Rear Axles

The sealed spindle keeps front axle bearings lubricated and protected from contaminants. The Cat “Live Spindle” design places the larger tapered roller bearing on the outside, where the load is greater, extending bearing life. A bolt-on modular rear axle improves serviceability and contamination control with easy access to differential components.

Hydraulic Brakes

Oil-bathed multi-disc service brakes are hydraulically actuated for smooth, predictable braking and lower operating costs. Brakes are located at each tandem wheel for a large total brake surface area to give you dependable stopping power and longer life.

Structures and Drawbar-Circle-Moldboard

Service ease and precise blade control

Caterpillar designs motor grader frame and drawbar components to give you performance and durability in heavy duty applications. The one-piece forged steel circle stands up to high stress loads, and a sacrificial wear system helps keep your service time and costs down. The articulation hitch features a large tapered roller bearing to carry loads evenly and smoothly. It is sealed to prevent contamination and a locking pin prevents articulation for safety during service or transport.

Blade Angle and Moldboard

An aggressive blade angle helps you work more efficiently by allowing material to roll more freely along the blade. Heat-treated rails, hardened cutting edges and end bits, and heavy duty bolts to give you greater moldboard reliability and long service life. The link bar allows extreme moldboard positioning for easier bank sloping and ditch cutting/cleaning.

Easy Maintenance for More Uptime

A series of shims, patented top-adjust wear strips and wear inserts are easy to add or replace. This keeps drawbar‑circle-moldboard components factory-tight for higher quality work, and saves you service time and costs. An adjustable rear circle drive reduces service time and reduces wear by keeping components tight.


Advanced machine control

State-of-the-art electro-hydraulics gives you advanced machine controls with precise and predictable movements.

Load Sensing Hydraulics (PPPC)

A proven load-sensing system and advanced Proportional Priority Pressure-Compensating (PPPC) electro-hydraulic valves give you superior implement control and enhanced machine performance. Continuously matching hydraulic flow/pressure to power demands creates less heat and reduces power consumption.

  • Consistent, Predictable Movement – PPPC valves have different flow rates for the head and rod ends of the cylinder, so you can count on consistent, predictable implement response.
  • Balanced Flow – Hydraulic flow is proportioned to give you confidence that all implements will operate simultaneously without slowing the engine or speed of some implements.

Blade Float

Allows the blade to move freely under its own weight. By floating both cylinders, the blade can follow the contours of the haul road. Floating only one cylinder permits the toe of the blade to follow a hard surface while the operator controls the slope with the other lift cylinder. An optional Variable Down Pressure feature allows you to select the amount of down force when the blade is in float. This helps you extend cutting edge life and is effective for removing snow and mud from a road surface.

Independent Oil Supply

Large, separate hydraulic oil supplies prevent cross-contamination and provide proper oil cooling, which reduces heat build-up and extends component life. Cat XT™ hose allows high pressures for maximum power and reduced downtime.

Integrated Technologies
