Ease of Operation

An updated cab provides greater visibility and comfort to help your operators work more productively. Single twist tiller control and optional automatic machine settings help reduce operator effort for greater efficiency.

Performance

A Cat C9 ACERT engine gives you the horsepower you need to doze through tough conditions. The new two-pump hydraulic system means you can count on simultaneous blade response and steering performance for greater precision and maneuverability. Differential Steering increases the speed of one track while slowing the other one down to give you exceptional turning, even with a full blade load.

Durability

Caterpillar elevated sprocket design offers added durability and optimum machine balance. Forestry, Waste Handling, and Cold Weather arrangements offer added features and protection to take on especially harsh environments.

Operator Environment

Implement and Steering Controls

D6R2 controls are ergonomically designed for low-effort and ease of operation.

  • The operator uses a single handle control to perform all direction and gear selection for ease of operation.
  • The tiller bar control allows the operator to work more precisely in close areas around structures, obstacles on the site and other machines.
  • Change gears up or down with the touch of a button.
  • Engine throttle speed is controlled by simply using a rotary dial.
  • Setting the engine throttle dial to the optional Auto Shift mode gives you two additional gear speeds. Auto Shift enables the machine to automatically down shift to the most effi cient gear based on load. This helps you save fuel and increase productivity.
  • Optional bi-directional control allows the operator to dial to preselected forward/reverse gears for reduced operator effort and improved effi ciency.
  • Pilot hydraulic implement controls reduce operator effort and offer more consistent, precise and responsive operation.
  • Implement Lock-Out prevents inadvertent operation of hydraulic attachments.

Power and Performance

Engine

Precise controls on the Cat C9 ACERT engine optimize power and fuel effi ciency while reducing emissions.

Planetary Power Shift Transmission

The proven, electronically controlled transmission features three speeds forward and three speeds reverse. The Auto Shift option adds two gear speeds for fi ve working speeds forward and four working speeds reverse. Large diameter, high capacity, oil-cooled clutches provide higher torque capacity and increase service life. Modular components offer easy service access.

Cooling System

A larger fan and updated aluminum bar plate cooling system is more effi cient than the previous model and gives you better cooling capability to handle high ambient conditions.

Differential Steering

Differential Steering increases the speed of one track while slowing the other one down to give you exceptional turning, even with a full blade load. This provides greater maneuverability and faster cycle times. You also get better load capacity, power and speed control in soft underfoot conditions.

Two-Pump Hydraulic System

New dedicated implement and steering pumps mean you can count on simultaneous blade response and steering performance. This gives you precision and maneuverability that is especially benefi cial for working in close quarters on construction sites or land clearing.

Load Sensing Hydraulics

Field-proven system senses load and uses a variable displacement piston pump to continuously adjust implement hydraulic power for maximum effi ciency.

Torque Divider

A single stage torque divider sends 70 percent of engine torque through a converter and the other 30 percent through a planetary gear set so you get more power to the ground.

Equipped for the Job

Structures

The foundation of every Cat dozer is a rugged mainframe built to absorb high impact shock loads and twisting forces. Castings add strength to the main case and equalizer bar saddle. A modular design allows easy installation and removal of major components for service/rebuild.

The pinned pivot shafts connect the mainframe and roller frames for independent oscillation. This provides strength and excellent ground clearance. The machine is able to better follow ground contours for maximum traction and operator comfort.

Bulldozers

L-shaped push arms give you an advantage over diagonal brace designs by bringing the blade closer to the machine. This gives you better balance, maneuverability and blade penetration. The design also gives you lateral stability and better cylinder positions for constant pryout capability regardless of blade height. The trunnion joint design requires no adjustments to keep the blade tight.

Dozer blades are manufactured from high tensile strength steel,with a robust multi-cell design to stand up to the most severe applications. The moldboard is highly abrasion resistant to prevent wear-through. Hardened bolt-on cutting edges and end bits give you better penetration and can be rotated and/or replaced for even longer blade service life. Semi-Universal, Straight and Angle Blades are available, as well as special blades for landfi ll and land clearing applications.

Undercarriage

The elevated sprocket design helps protect major components from harsh impacts and provides a modular design for convenient service. The operator has excellent sight lines to the blade, sides and back of the machine. The center of gravity remains low, offering excellent stability, balance and traction.

Heavy Duty undercarriage, with lifetime lubricated track/carrier rollers and idlers, is standard on the D6R2. The components are designed for extended wear life in abrasive or high impact conditions like forestry, side slopes or working in rocky terrain. Or, choose SystemOne™ undercarriage (XL and LGP tractors) designed to work and wear as a system for longer life and lower costs in abrasive or low/moderate impact applications.

A broad choice of track shoe designs and widths help you further optimize your machine for performance and longer life.

Integrated Technologies

LINK Technologies

LINK technologies, like Product Link™*, are deeply integrated into your machine and wirelessly communicate key information, including location, hours, fuel usage, idle time and event codes.

Product Link/VisionLink®*

Manage equipment with real-time data and performance information to help make timely, decisions that can boost job site effi ciency and productivity, and lower costs. Analysis and scheduling tools help you track routine maintenance and plan for service procedures. And if a problem arises, operators can quickly assess the issue and take appropriate action to minimize service costs and downtime.

Whether you’re in your office or on the job site, you can easily access data about your machine or fleet via the online VisionLink user interface from your computer or mobile device. * Product Link/VisionLink mobile not available in all areas. Please consult your Cat dealer.

GRADE Technologies

GRADE technologies combine digital design data and in-cab guidance to help you reach target grade quickly and accurately, with minimal staking and checking. That means you’ll be more productive, complete jobs faster, in fewer passes, using less fuel, at a lower cost.

Cat AccuGrade™

AccuGrade is an optional dealer-installed grade control system that provides automated blade slope and elevation control, improving productivity and accuracy by up to 50 percent over conventional methods. Real-time in-cab guidance indicates precisely where to work and how much to cut or fi ll, helping operators work more confi dently and get to grade faster, in fewer passes, using less material, fuel, and costs. Choose from 2D laser systems for flat planes and slopes, and 3D satellite (GNSS) for large complex designs or total station (UTS) control for fi ne and fi nish grading. 3D systems eliminate staking, checking, and ground crews, making the job site safer and more cost effective.

Special Arrangements
