2. Identify apps quickly with a grid list view, abbreviated app names, and categorized menu options.
    
3. A new notification center keeps important information visible to the operator, and displays messages without shrinking the camera view.
    
4. Color coded notifications set critical messages apart from the rest.
    
5. Use the in-monitor QR code to learn about machine technology and features through a full suite of "how-to" videos.

    
1. Operator Coaching is an in-cab system that recognizes specific opportunities for operators to be more productive and prevent unnecessary machine wear and tear.
    
2.  After detecting inefficient or restricted actions, the system alerts the operator and provides insight into the inefficiency and steps to improve.
    
3. Paired with a VisionLink Productivity subscription, this information and other Operator Coaching insights can be viewed from anywhere.

    
• Standard integrated vehicle health management system alerts the operator with service guidance and parts needed to enhance uptime.    
    
• Enhance visibility to make service work easier and safer with optional inspection lighting.

High Performance

    
• The C9.3B engine generates more power than the 2020 model year 336 engine.
    
• More power to the pumps, wider undercarriage, and heavy counterweight enable up to 10 percent more productivity.
    
• Match the excavator to the job with three power modes – Power, Smart, and Eco. Power mode is maximum power all the time. Smart mode automatically matches engine and hydraulic power to digging conditions, providing maximum power when needed and reducing power when it isn’t to help save fuel. Eco mode reduces engine speed and keeps it constant to reduce fuel consumption.

Efficiency Through Technology

    
• Boost productivity up to 45% versus traditional grading with standard Cat Grade with 2D system – includes indicate-only and laser capability.​
    
• Want a 3D system to improve your digging results? Caterpillar's 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.​
    
• Standard Grade Assist helps you stay on grade – simply and effortlessly – with single-lever digging.​
    
• Dig with guidance to depth, slope, and horizontal distance to grade. You can set up to four different depth and slope targets to help save time and money.​
    
• Automatically stop excavator swing at operator-defined set points in truck loading and trenching applications with Swing Assist.​
    
• 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.​
    
• Combine Payload with VisionLink® and remotely manage your production targets.​
    
• Operator Coaching is an in-cab system that recognizes specific opportunities for operators to be more productive and prevent unnecessary machine wear and tear.  

Take The Guesswork Out of Managing Your Equipment

    
• ​VisionLink® provides actionable data insights for all assets - regardless of fleet size or equipment manufacturer.* Review equipment data from your desktop or mobile device to maximize uptime and optimize assets. Dashboards provide information such as hours, miles, location, idle time, and fuel utilization. Make informed decisions that lower costs, simplify maintenance, and improve safety and security on your jobsite.​
    
• VisionLink® Productivity gathers and summarizes machine telematics and jobsite data from all your equipment – regardless of the manufacture.* View actionable information such as idle time, fuel burn, location, payload, load counts, total cycles, and more to improve machine efficiency, productivity, and utilization. Access data anywhere via a mobile, tablet, or desktop device - on or off the jobsite.​
    
• Cat® Inspect is a mobile application that allows you to easily perform digital preventative maintenance (PM) checks, inspections, and daily walkarounds. Inspections can easily be integrated with other Cat data systems like VisionLink® so you can keep a close eye on your fleet.​
    
• Remote Troubleshoot is a mobile application that allows your Cat dealer to perform diagnostic testing on your connected machine remotely to help ensure that issues are resolved quickly and with less downtime.​
    
• Remote Flash is a mobile application that allows you to update onboard software without a technician being present, allowing you to initiate software updates when convenient, increasing your overall operating efficiency.​
    
• The Cat PL161 attachment locator allows you to track attachments across all worksites, reduce the number of lost attachments, and plan for attachment maintenance and replacement. The work tool recognition feature automatically adjusts machine settings based on the selected tool.​

* Data field availability can vary by equipment manufacturer.

Built for Rugged Conditions

    
• Reinforced structures ensure long-term durability in harsh environments.

Simple to Operate

    
• Start the engine with the push of a button; use a Bluetooth key fob or Operator ID passcode.
    
• Program each joystick button, including power mode, response, and pattern, using Operator ID; the machine will remember what you set each time you go to work.
    
• Trouble cutting through tough material? Auto dig boost gives you an automatic power increase of 8 percent when you need it for better bucket penetration, shorter cycle times, and greater payloads.
    
• Need more lift during your shift? Auto heavy lift gives you 8 percent more power exactly when you need it for as long as you need it.
    
• Make moving the excavator much easier with optional Cat Stick Steer. Simply push a button and use one hand to travel and turn instead of both hands or feet on levers or pedals.
    
• Make operating easier with the touch of a joystick button. An auxiliary relay allows you to power on or turn off a CB radio, beacon light, and even a dust suppression watering system without taking your hands off the joysticks.
    
• Cat continues to improve user interface functionality for operators of all skill levels. The touchscreen monitor is an easy-to-use operating tool that presents the jobsite dashboard with an intuitive format. Productivity applications are displayed in grid-view to read on-the-go, and touchscreen navigation is programmed to make sure job performance continues without any hold ups.
    
• Protect your hammer from overworking. Auto hammer stop warns you after 15 seconds of continuous firing and then automatically shuts it off after 30 seconds – all to prevent wear and tear on the attachment and excavator.
    
• 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.

Safety

    
• 2D E-Fence prevents the excavator from moving outside of operator-defined set points; the system works with thumb and bucket combinations along with hammer, grapple, and clamshell attachments.
    
• Cat Detect - People Detection helps protect the most valuable asset on any jobsite – people. The system uses smart cameras with depth sensors to provide the operator with visual and auditory alerts so he or she can take immediate action when a person is too close to the excavator.
