The new D7 adds powerful , efficient choice to the Cat dozer line-up at 197kW ( 265hp ) and an operating weight of 29 776kg .
Additional Value Blade capacity is increased by 10 %, and a dedicated steering pump provides more continuous push when turning under load for raised productivity .
The machine is driven by a new smooth-shifting fully automatic 4-speed transmission . Operators do not need to shift gears – once the desired ground speed is chosen , the transmission continuously adjusts for maximum efficiency and power to the ground without added operator input . This prevents overheating in hot climates , offers better speed control and provides more power to the ground .
The redesigned cab offers Integrated Roll Over Protective Structure ( ROPS ) providing added visibility to the sides of the dozer . Operators will find more space , an air suspension seat with multiple adjustments , and an 8-inch ( 200mm ) gauge cluster operator interface with a view of machine / service functions and settings . An optional premium cab provides fully adjustable armrests , plus an easy-to-use 10-inch ( 254mm ) touchscreen operator interface with high-definition rearview camera . Four LED lights are standard , with options for packages of 6 or 12 lights .
A heavier frame , D8-sized structures and a new track roller frame with larger roller shafts add durability . Heavy Duty Extended Life undercarriage – HDXL with DuraLink – provides up to 20 % more seal life in high impact conditions . While a redesigned fuel system provides greater reliability and more accurate fuel delivery .
A Ground Level Service Center allows for easy access to the disconnect switch and can be outfitted with an optional hour meter and access / egress light switch . A railing , with integrated shovel holder , is available to help make fuelling easier .
Technology Choices All the technology features are designed to help new operators become more productive sooner , and to assist experienced operators get the job done faster , with less effort . Slope Indicate is standard on all machines , showing machine main fall and cross-slope on the main display .
ARO with Assist is a grade-control-ready option bundled with operator assist features that work in the background .
• Cat Grade with Slope Assist maintains the operator ’ s predetermined blade position – either main fall or cross slope – without a GPS signal or extra hardware . Works in manual or automatic modes .
• Factory Attachment Ready Option ( ARO ) provides optimal mounting locations , brackets , and hardware , simplifying installation of any brand of grade control system .
• Blade Load Monitor gives real-time feedback on current vs . optimal blade load to optimise blade capacity .

• Stable Blade works seamlessly with operator blade inputs for smoother surfaces .
• Traction Control automatically reduces track slip to save time , fuel , and track wear .
• AutoCarry automates blade lift to help maintain consistent blade load and help reduce track slip .
Integrated Cat Grade with 3D is an optional GPS system which automates blade movements in both fine grading and production dozing applications , reducing manual operator inputs by as much as 80 %. Small antennas are integrated into the cab roof for better protection and GPS receivers are mounted inside for security . An intuitive 254-mm ( 10-in ) Grade operator interface works like a smart phone , making it easy for operators to pick up quickly . Android OS platform allows installation of custom apps .
Greater Efficiency Cat Link telematics technology gathers data generated by equipment , materials , and people – and delivers it in customisable formats .
• Product Link collects data automatically from equipment assets – any type , any brand – which can be viewed online through web and mobile applications .
• Access information anytime , anywhere with VisionLink . Cat dealers can help configure a customised subscription , available with cellular or satellite .
• The Cat App helps manage machine assets – at any time – from a smartphone .
• Remote Troubleshoot allows the Cat dealer to perform diagnostic testing remotely . Remote Flash updates on-board software without a technician being present , at a convenient time , potentially reducing update time by as much as 50 %.
• Application Profile and Operator ID saves preferred machine settings .
• Machine Security – A passcode provides an optional level of security by requiring an operator to enter an ID before the machine will start .
D7 can be optimised for intended applications with a variety of blade and track shoe choices . The standard track configuration puts more track on the ground , like the D7R ’ s XR undercarriage , for improved balance .
The D7 can come with specialised guarding to take on any challenge . In addition to machine protection against impact and airborne debris , these specialty dozers can be ordered with an impact-resistant cab , application-specific undercarriage , and a specialty blade . •
Spacious cab resets the industry standard for comfort , visibility , and ease of operation . Optional Premium cab features include 10-inch ( 254mm ) touch screen display and air suspension seat with adjustable armrests .
