Introducing Cat® Power to the Ground for Cat® Motor Graders
Redesigned Cab
Built for Your Comfort
Stay comfortable all shift with improved climate control and a seat that adjusts to fit you. With more options to fine-tune your setup, you can reduce fatigue and keep working strong, even on long days.
See More, Work Safer
The redesigned cab gives you a clear view of the ground and your work area, so you can operate with confidence. Add optional rear, front, and 360° cameras displayed right on the main screen to help you stay aware of what’s around you and keep the jobsite safe.
Simple Controls, Easy Operation
Everything you need is right where you expect it. Grouped controls and an easy-to-use layout make adjustments quick and straightforward, so you can stay focused on the job and keep things moving without slowing down.
Safety
Safe Start Every Time
The machine won’t move until you’re in the seat and ready to go. The operator presence monitor keeps the parking brake on and disables hydraulics until everything is set. When you’re traveling, hydraulic lockout keeps your implements from moving while you still have full steering control.
Stay in Control on the Move
As you pick up speed, Speed Sensitive Steering automatically adjusts to keep handling smooth and predictable. If steering pressure drops, the secondary steering system kicks in so you can safely steer the machine to a stop without losing control.
See Clearly, Day or Night
Anti-glare paint helps cut down eye strain when you’re working at night. Add the LED light package, and you’ll have the visibility you need to keep working safely and accurately after the sun goes down.
Easy Access and Built-In Protection
Fuel up from the ground—no climbing required. Walkways, perforated platforms, and grab rails help you keep three points of contact when getting on, off, or around the machine. The slip clutch and optional blade lift accumulators help absorb impacts, protecting the machine and keeping operation smooth and safe.
Technology
See What Your Machine Is Doing
With built-in tech, you can see how your grader is working in real time. Keep an eye on performance, catch problems early, and make better calls on the job. Less guessing means smoother work, better efficiency, and more done in a day.
Ready for Grade Right Away
The Cat® Grade ARO sets your machine up for grade control from the start. It makes adding or upgrading grade systems quick and easy, so you’re not stuck with long installs or downtime. When you’re ready to step up your accuracy, your machine is ready too.
Hit Grade Faster with 3D
Cat Grade with 3D helps you get to grade faster without all the extra effort. Blade movements are automatic, so you don’t have to constantly adjust. With fewer passes and less rework, you save time, cut fuel use, and get consistent results every shift.
Hold Slope Without the Work
Cross Slope Assist helps you keep grade without fighting the controls. The system manages one side of the blade while you run the other, so it’s easier to stay smooth and consistent. You spend less time correcting and less energy getting the job done.
Stay Connected and Keep Moving
Tools like VisionLink®, VisionLink Productivity, Cat Inspect, and Remote Troubleshoot help you stay on top of your machine. Track performance, handle inspections, and get remote support when needed. That means less downtime and more time pushing dirt.
Power to the Ground. Performance that Delivers.
A new specification is now available on Next Generation Cat® Motor Graders, showing the actual power to the ground performance. Cat updated the power strategy (called Power to the Ground) so the machine now delivers consistent power in every condition – hot or cold weather, heavy or light load. This means the grader feels more stable, more predictable, and easier to control, especially when fine‑grading.
You still get the same real‑world productivity, with smoother operation and better fuel efficiency.
More Consistent Power to the Ground
With true constant net power, the machine delivers consistent power regardless of temperature or load, providing more predictable grading performance and better machine feel and control—especially for fine grading.
Improved Grading Quality with Integrated Control Technologies
A more stable power curve allows Cat Grade with Cross Slope, Stable Blade, and 3D Grade to operate more accurately, improving automated blade control response with consistent, predictable power.
No Loss in Real-World Productivity
Next Generation Cat motor graders deliver the same legendary performance for road building, site prep, ditching, and snow removal—now with the latest design evolution.
Better Fuel Efficiency
Power to the Ground supports smoother operation and reduced fuel burn by avoiding unnecessary power spikes, allowing the machine to run in optimized power more often.
Lower Maintenance Costs
Fast, Easy Daily Checks
Daily checks are quick and easy with filters grouped at ground level, so you don’t have to climb around the machine. Wide-swinging engine doors and removable side panels give you clear access to service points, making it faster to get your walkaround done and get back to work.
Save Fuel and Stay Productive
You can save fuel and keep things running efficiently without extra effort. Just turn on Eco mode during lighter work to cut fuel burn. The optional reversing fan helps keep the cooling system clean, so you’re not dealing with buildup—just a quick weekly clean helps keep uptime high.
Built for Durable, Low-Maintenance Grading
When you’re on the blade, you’ve got durable components built to last. The standard drawbar, circle, and moldboard are tough for everyday work, while the top adjust drawbar helps you fine-tune for tighter grading and lower maintenance. If you want even less upkeep, the optional High Performance Circle gives you smooth blade rotation and cuts down on regular adjustments and wear part changes.
Sustainability
Meets Emissions Standard and Gives You Fuel Options
The Cat engine helps you meet Tier 4 Final and Stage V emissions standards, so you can work anywhere with confidence. It runs on ultra‑low sulfur diesel and can also use approved lower‑carbon fuels like biodiesel blends or renewable diesel, giving you flexibility on the job without changing how you operate.
Cuts Fuel Waste and Helps You Work Smarter
Built-in features help you save fuel without extra effort. The Engine Idle Shutdown Timer turns the machine off after sitting too long, so you’re not burning fuel doing nothing. Cat® Grade helps you get to grade faster and more accurately by assisting with blade control, cutting down on rework and unnecessary passes.
