Sound Level Information for Machines in European Union Countries and in Countries that Adopt the “EU Directives.” The information below applies to only the machine configurations that have the “CE” mark on the Product Identification Plate. (1) | The declared dynamic operator sound pressure level is 76 dB(A) when “ISO 6396:2008” is used to measure the value for an enclosed cab. The measurement was conducted at 70% of the maximum engine cooling fan speed. The sound level may vary at different engine cooling fan speeds. The cab was properly installed and maintained. The measurement was conducted with the cab doors and the cab windows closed. NOTE: This dynamic operator sound pressure level is associated to a 2 dB(A) uncertainty. |
Sound Level Information for Machines in European Union Countries and in Countries that Adopt the “EU Directives.” The information below applies to only the machine configurations that have the “CE” mark on the Product Identification Plate. (2) | If equipped, the certification label – 110 dB(A) – is used to verify the environmental sound certification of the machine to the requirements of the European Union. The value that is listed on the label indicates the guaranteed exterior sound power level (LWA) at the time of manufacture for the conditions that are specified in “2000/14/EC.” Your machine may have a different value. |
Sound Level Information (1) | The operator Equivalent Sound Pressure Level (Leq) is 81.5 dB(A) when “ANSI/SAE J1166 FEB2008” is used to measure the value for an enclosed cab. The measurement was conducted at 100% of the maximum engine cooling fan speed. This is a work cycle sound exposure level. The cab was properly installed and maintained. The test was conducted with the cab doors and the cab windows closed. |
Sound Level Information (2) | Hearing protection may be needed when the machine is operated with an open operator station for extended periods or in a noisy environment. Hearing protection may be needed when the machine is operated with a cab that is not properly maintained, or when the doors and windows are open for extended periods or in a noisy environment. |
Sound Level Information (3) | The average exterior sound pressure level is 85.5 dB(A) when the “SAE J88 FEB2006 – Constant Speed Moving Test” procedure is used to measure the value for the standard machine. The measurement was conducted under the following conditions: distance of 15 m (49.2 ft) and “the machine moving forward in an intermediate gear ratio.” |

A Cat C7.1 ACERT engine gives you the power and reliability you need. Improved fuel economy over the previous model and efficient use of Diesel Exhaust Fluid (DEF) gives you excellent overall fluid efficiency.
A single plane design makes cleanout easier, and durable aluminum bar plate construction gives you superior heat transfer and corrosion resistance. A swing-out door provides easy access for cleanout.
Transmission controls will automatically select the drive mode best suited to your application, providing increased productivity and efficiency.* The new transmission with a lock-up clutch torque converter gives you the performance of direct drive with the ease of operation of power shift.
Standard Enhanced Auto Shift helps you save fuel by automatically upshifting/downshifting to maintain the most efficient gear based on load. Three different settings – 3-speed, 6-speed and fine adjustment mode – allow you to optimize tractor performance to match material and job site conditions.
Differential Steering maintains full power to both tracks for best-in-class turning, even with a full blade load. When one track speeds up, the other slows down an equal amount, so you have better maneuverability and faster cycle times. Load capacity, power and speed control are also better when working in soft conditions.
Field-proven system senses the load and continuously adjusts hydraulic power to your blade to maximize efficiency.
Elevated sprocket helps protect major components from harsh impacts and provides a modular design for convenient service.
Semi-Universal and Straight blades are designed with a strong box section to stand up to the most severe applications. Heavy moldboard construction, hardened bolt-on cutting edges and end bits add strength and durability.
To help you match your D6N to the task at hand, you can outfit your D6N with a multi-shank ripper, winch or drawbar.
LINK technologies provide wireless capability to machines enabling two-way transfer of information collected by on-board sensors, control modules, and other Cat Connect technologies using off-board apps, such as our VisionLink® software.
Product Link takes the guesswork out of equipment management. Track location, hours, fuel usage, productivity, idle time, and diagnostic codes through the online VisionLink interface. Manage your fleet in real time so you can maximize efficiency, improve productivity, and lower operating costs.
Cat Connect GRADE technologies help you hit target grade faster and more accurately. Finish jobs in fewer passes, and with less operator effort, saving you time and helping you increase profit.
To meet the additional 80 percent reduction in NOx emissions required by Tier 4 Final/Stage IV emission standards, Caterpillar engineers added Selective Catalytic Reduction (SCR) to the already proven aftertreatment solution.
Selective Catalytic Reduction utilizes Diesel Exhaust Fluid (DEF), which can be conveniently refilled when you refuel. The DEF fill nozzle is located next to the fuel tank, with easy access via a rear step. A tone will sound (with key on), when the tank is nearly full and a gauge on the dash shows your fluid level. The system is designed to use one tank of DEF for each tank of fuel (1:1 DEF fill ratio). The D6N typically has used DEF at a rate of 2-3 percent of fuel consumption.
The D6N is designed to help you get routine service done quickly and efficiently so you can get to work.
