MOTEUR

Comfort and productivity

BENEFITS AND FEATURES

An updated cab, with an Integrated Roll Over Protection Structure (ROPS), gives operators greater all around visibility to enhance safety and productivity. It offers a quieter interior, with improved pressurization to help keep dust out for a cleaner operating environment. The standard suspension seat offers eight operator adjustments and adjustable armrests for greater comfort. The seat also features an integrated, retractable 76 mm wide (3 in) seat belt for enhanced safety.

The redesigned instrument panel has easy-to-read gauges showing fuel level and engine speed, as well as temperature levels for power train oil, hydraulic oil and engine coolant.

The updated Cat Electronic Monitoring System has three levels of machine monitoring and warnings. Lights and/or alarms keep operators informed about conditions like restrictions to engine intake air, power train or fuel filters or water in the fuel.

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 efficient 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 efficiency.
  • Pilot hydraulic implement controls reduce operator effort and offer more consistent, precise and responsive operation.
  • Implement Lock-Out prevents inadvertent operation of hydraulic attachments.
Operator Environment

Designed to get the job done

BENEFITS AND FEATURES

Engine Precise controls on the Cat C9 ACERT engine optimize power and fuel efficiency 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 five 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 efficient 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 beneficial 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 efficiency.

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.

Power and Performance

Tough from the inside out

BENEFITS AND FEATURES

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 landfill 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.

Rear Implements A three-shank fixed parallelogram-type ripper is available with curved or straight ripper shanks. An updated design has fewer grease points for reduced maintenance and longer service life.

Rear counterweights optimize balance for backing up steep slopes or increasing performance in heavy dozing applications.

Choose a drawbar for towing and recovery, or outfit your D6R2 with a winch.

Please consult your Cat dealer for available options to best suit the types of work you do.
