Boost productivity up to 45 percent vs traditional grading with the standard Cat Grade with 2D system.
Dig with real-time guidance on depth, slope, and horizontal distance to grade.
The 2D system is upgradable to Cat Grade with Advanced 2D or Cat Grade with 3D.
Standard Grade Assist –

Stay on grade – simply and effortlessly -with single-lever digging.
Set your desired bucket angle and let Bucket Assist automatically maintain the angle in sloping, leveling, fine grading, and trenching applications for easy, accurate, and fast jobs.
Keep your tracks on the ground in lifting and hard digging with Boom Assist.
Automatically stop excavator swing at operator-defined set points in truck loading and trenching applications with Swing Assist, which will help you use less effort and consume less fuel.

Standard Cat Payload on-board weighing system –

Cat Payload helps you achieve precise load targets to improve your operating efficiency. Pick up a load of material–with a bucket and thumb combination or grapple and clamshell attachments–and get a real-time weight estimate without swinging.
Track your daily productivity such as truck target weights and load/cycle counts.
Calibration can be performed in a matter of minutes.
Combine Payload with VisionLink® and remotely manage your production targets.
Take Payload data with you. The monitor’s USB port lets you download results so you can manage progress without an internet connection or VisionLink® subscription.

Upgrade to optional Cat Grade with Advanced 2D –

Want a 3D system to improve your digging results? Caterpillar’s new single antenna global navigation satellite system (GNSS) makes it easy by giving you visual and auditory guidance to grade. Plus you can create and edit designs on the touchscreen monitor while you’re on the job. If your application calls for a dual antenna system, it’s easy to upgrade.
Upgrade to our dual antenna GNSS for maximum grading efficiency. The system lets you create and edit designs on the touchscreen monitor while you’re on the job, or you can have the plan design sent to the excavator to make your work easier. Plus you get added benefits of avoidance zones, cut and fill mapping, lane guidance, and augmented reality along with advanced positioning capability.
Already invested in another brand’s 3D system? No problem. Standard Cat technology like Grade with 2D can readily integrate with that system to give you the precise results you need.

Get remote services –

Remote Troubleshoot connects you to a dealer service pro to help solve your problem and quickly get you to work.
Remote Flash works around your schedule to ensure your machine’s software is up to date for optimal performance.
The Cat App helps you manage fleet location, hours, and maintenance schedules; it also alerts you for required maintenance and even allows you to request service from your local Cat dealer.

Standard Product Link™ provides location, machine hours, fuel usage, productivity, idle time, diagnostic codes, and other machine data on demand through VisionLink® online interface, helping you improve jobsite efficiency with lower operating costs.
Improve your accuracy and safety – Add a new Cat Tiltrotator system upgrade with factory-fit joysticks. The system allows a Tiltrotator to work with standard Cat 2D Grade and E-Fence; it uses the standard cab monitor to display the tool and engage its SecureLock™ so you don’t need spend money on an extra monitor.
All Cat Grade systems are compatible with radios and base stations from Trimble, Topcon, and Leica. Already invested in a grade infrastructure? You can install grade systems from Trimble, Topcon, and Leica onto the machine.

Cab options let you choose the level of comfort you need.
Enjoy wide spacing between consoles for a more spacious comfortable environment.
Sit in new, wide seats that adjust for operators of all sizes (heated and heated/cooled options are available).
Get in and out of the cab easier using the tip-up left console (Deluxe and Premium cabs only).
Control the excavator comfortably with easy-to-reach controls located in front of you. Standard automatic climate control keeps you at the right temperature throughout your shift.
Improved viscous mounts reduce cab vibration by up to 50% over our previous excavator models.
Stow your gear with plenty of in-cab storage behind the seat, overhead, and in the consoles.

Protect hydraulic components in cold weather. The auto warm-up feature speeds hydraulic oil warming in cooler temperatures.
The fuel system is protected from contamination of fuel by three levels of filtration.
Bottom guarding protects engine and hydraulic components from damage while swinging and traveling.
The hydraulic tank with a new oval shape designed to improve stress resistance.
The strong X-structure lower frame carries loads from the excavator’s upper structure to the track.
Travel motor hydraulic lines are routed inside of the frame to protect them from damage.
The sloped track frame design prevents mud and debris from accumulating and damaging tracks.
The grease lubricated tracks have grease sealed between the pin and bushing to prevent debris from entering and reducing life.
The track rollers are rebuild-able and sealed to prevent dirt and debris causing wear of internal components.
A bolt-on track guiding guard helps maintain track alignment while traveling or working on slopes.

Start the engine with a push button; use a Bluetooth key fob, or the Operator ID passcode.
Program each joystick button, including response and pattern, using Operator ID; the machine will remember what you set each time you go to work.
Program up to four depth and slope offsets so you can easily get to grade without a grade checker – a real time saver and safety enhancer on the jobsite.
Save more time and energy with available work tool recognition. A simple shake of the attached tool confirms its identity; it also ensures all the attachment settings are correct so you can get to work quickly and efficiently.
Navigate quickly on the standard high-resolution 203 mm (8 in) touchscreen monitor, or with the optional 254 mm (10 in) touchscreen monitor, or with the aid of the jog dial control.
Protect your hammer tool from overheating and rapid wear. Auto hammer stop warns you after 15 seconds of continuous firing and then automatically shuts it off after 30 seconds – all to extend the tool’s service life.
A second 254 mm (10 in) monitor is available for the advanced grade control.
Not sure how a function works or how to maintain the excavator? Always have the operator’s manual at your fingertips in the touchscreen monitor.
The Cat PL161 attachment locator is a Bluetooth device that makes finding your attachments and other gear quick and easy. The excavator’s onboard Bluetooth reader or Cat App on your phone will locate the device automatically.
