Unprecedented precision and ease of operationLearn More
Operators are more comfortable and productive with two electro-hydraulic joysticks. New and experienced operators around the world report that the controls are easy to learn, and that the electronically adjustable control pods help position them for optimal comfort, visibility and proper operation.
The left joystick controls steering, articulation, return-to-center, wheel lean, gear selection, left moldboard lift cylinder and float.
The right joystick controls drawbar, circle and moldboard functions as well as electronic throttle control and manual differential lock/unlock.
Joystick lean angle mirrors the steer tires’ turning angle. A brake tensioning system holds the joystick in position until the operator moves it. The steering control automatically reduces steering sensitivity at higher ground speeds for predictable control. Infinitely variable roller switches control of the rear ripper and/or front lift group (when equipped).
Electronic Throttle Control
Provides easy, precise and consistent throttle operation. An automatic/manual mode switch offers flexibility for different applications and operator preferences.
Automatically returns the machine to a straight frame position from any angle with the touch of a button.
Power and reliabilityLearn More
The Cat C18 engine with ACERT™ Technology gives you the performance you need to maintain consistent grading speeds for maximum productivity. Superior torque and lugging capability provide the power to pull through sudden, short-term increases in loads.
ACERT Technology lowers combustion chamber temperatures and optimizes fuel combustion to generate more work output for your fuel cost. ACERT engines also generate fewer emissions to meet the needs of operations around the world.
Hydraulic Demand Fan
The hydraulic demand fan automatically adjusts the cooling fan speed according to engine cooling requirements. When cooling demand is reduced, you benefit from more power to the ground and improved fuel efficiency.
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 feature helps cold-weather startups in extreme temperatures.
Maximum power to the groundLearn More
We designed the 24M to give you efficiency and longevity in your most demanding applications.
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.
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.
Service ease and precise blade controlLearn More
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.
The moldboard features heat-treated rails, hardened cutting edges and end bits, and heavy duty bolts to give you greater reliability and long service life. Optimized moldboard curvature and large throat clearance help you move material more efficiently.
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 light. Six bolt-on tooth segments on the circle can be individually replaced to reduce cost and downtime for maintenance.
Advanced machine controlLearn More
State-of-the-art electro-hydraulics give 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.
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.
Solutions to make work easier and more efficientLearn More
VIMS uses on-board sensors to monitor a wide range of vital machine functions. If an abnormal condition is detected, it will alert the operator and instruct them to take appropriate action. This improves availability, component life and production while reducing repair cost and the risk of a catastrophic failure.
Cat Grade Control Cross Slope
Cross Slope is a fully integrated, factory installed system that helps your operator more easily achieve the desired cross slope by automating one end of the blade. The system is scalable, supporting all two- and three-dimensional upgrades to be fully compatible with all AccuGrade™ kits.
