Overview

Reliable and Comfortable at Lower Cost

The Cat® 120 GC Motor Grader is easy to own and operate. A demand fan and standard Eco mode reduces fuel consumption while open access to maintenance points makes service quick and simple. Control the blade with consistent precision using lever controls from the comfort of the cab.

Benefits

Operate in Comfort

Boost productivity and comfort with adjustable seat and a ventilation system option.

Low Cost-Per-Hour Operation

Keep costs down with extended maintenance cycles and reversing fan option while saving on fuel with Eco mode.

Reliable Performance

Precise blade movement and power with the C4.4 engine helps to get the job finished on-time and budget.

Features at a Glance

Productive and Economical

Increase your fuel economy up to 5% with the standard Eco mode.
The on-demand fan reduces fuel consumption and under-hood heat for longer component life.
Improve productivity with Electronic Throttle Control which matches engine power and torque to application requirements.
The powershift transmission and machine-balanced design ensures you get full drawbar power to the ground with the powerful Cat C4.4 engine.
The hydraulic system makes the 120 GC motor grader more precise and predictable for a consistent grade.
The all-wheel drive (AWD) option assists with traction and maneuvering the machine. The increased power helps you to handle slopes and loose material better.
The Digital Blade Slope Meter option shows you the grade without relying on manual grade checkers.
Product Link provides location, machine hours, fuel usage, productivity, idle time, diagnostic codes, and other machine data ondemand through the VisionLink online interface, which helps you improve jobsite efficiency with lower operating costs.

Cab Keeps You Comfortable All Day Long

Choose your comfort level in the cab with standard, mechanical suspension or air suspension seat.
Easily adjust the control console and steering wheel.
The high capacity heating, ventilation and air conditioning (HVAC) system option circulates fresh air, prevents dust entry, and keeps windows from fogging.
Quickly find your current gear in the front display.
Easily add a radio to the cab using the built-in mounting location option.

Reliable Performance

The drawbar circle moldboard stays factory tight providing precision grading pass after pass.
The machine structure is built for a long life. It is designed to use several types of work tools, such as a front blade.
A slip clutch option protects the circle drive if the machine strikes an immovable object.
The front axle maximizes bearing life while also minimizing maintenance.
Reduce daily greasing requirements and costly repairs to your circle and pinion with the Circle Saver option.

Safely Home Every Day

See what's behind you with the rear camera option. The dedicated display can be always on to ensure a safe workenvironment.
In the event of an engine stall, count on the secondary steering system option to help stop the machine safely.
Use three points of contact when entering and exiting the machine with strategically placed walkways and grab rails.
The optional four-point safety harness seat belt provides extra protection.
Ground level engine shut-off switch stops all fuel to the engine when activated and shuts down the machine.
See the rear of your machine with side and rearview mirrors.
Work past sundown using the strategically placed lights for nighttime visibility.

Maintenance Made Easy

Fuel filters, engine air filters, and oil filters are grouped together for easy access and preventative maintenance.
The standard drawbar circle moldboard increases durability using hardened circle teeth and replaceable wear inserts to help sustain factory tightness.
Brake adjustments are maintenance free and easily accessible.
The standard bottom guard shields the transmission and filter. Optional guarding protects your machine from damage in demanding applications.
Spend less time cleaning the cooling system with the reversing fan option, which reduces costs when cleaned once per week for more uptime.
The new hydraulic system includes integrated work port pressure relief, an integrated dead engine implement lower, and reduction in leak points for safety and quality.

Attachments to Fit Your Needs: Improve performance and efficiency of the 120 GC with the push block option.

Ripper and scarifier options are available to assist with grading hard ground.

Add the front blade option to spread more material faster.

The optional tow hitch allows you to tow equipment or implements behind the machine.

Sustainability

The Cat® C4.4 engine meets U.S. EPA Tier 4 Final, EU Stage V, and South Korea MOE NR Tier 4 Final emission standards.
Cat diesel engines are required to use ULSD (ultra-low sulfur diesel fuel with 15 ppm of sulfur or less) or ULSD blended with the following lower-carbon intensity fuels up to: 20% biodiesel FAME (fatty acid methyl ester)* or 100% renewable diesel, HVO (hydrotreated vegetable oil) and GTL (gas-to-liquid) fuels. Refer to guidelines for successful application. Please consult your Cat dealer or "Caterpillar Machine Fluids Recommendations" (SEBU6250) for details.
Cat® Grade helps reduce fuel burn and greenhouse gas emissions by enabling you to achieve grade faster and more accurately by automating blade actions.
Cat Scheduled Oil Sampling (S O S) Services help reveal excessive wear, contaminated fluids, or other unseen issues that can shorten component life. In many cases, you can extend oil and coolant change intervals by using fluid monitoring. Consult your Cat dealer or the machine's operation and maintenance manual for more information.
Extended maintenance intervals not only reduce downtime but decrease the amount of fluid and filters that are replaced over the life of the machine.
VisionLink displays the CO2 emissions for monitored assets, calculated by fuel type for the Runtime Fuel Burned each day in a selected date range.
Don't waste fuel idling. Cat VisionLink online fleet monitoring helps you manage idle time and reduce fuel burn and greenhouse gas emissions.
Cat® Reman parts are a sustainable choice. New Cat parts are designed with the potential to have more than one life, so Cat Reman parts are truly remanufactured not just repaired, rebuilt, or reconditioned. Because the process ensures the latest design changes are incorporated into Cat Reman parts, you get like-new quality and outstanding performance at lower cost.

*Engines with no aftertreatment devices can use higher blends, up to 100% biodiesel (for use of blends higher than 20% biodiesel, consult your Cat dealer).
