Structures and Drawbar-Circle-Moldboard
Caterpillar designs frame and drawbar components for performance and durability in heavy duty applications. The one-piece forged steel circle stands up to high stress loads, and a sacrificial wear system helps keep your service time and costs down. The articulation hitch features a large tapered roller bearing to carry loads evenly and smoothly. It is sealed to prevent contamination and a locking pin prevents articulation for safety during service or transport.
Easy Maintenance for More Uptime
The drawbar, circle and moldboard are designed to make it easy to keep the components tight. One person can easily adjust or replace the patented top-adjust drawbar wear inserts from the top of the drawbar plate, reducing downtime to save you money. Durable nylon composite wear inserts maximize circle torque and component life. Sacrificial brass wear strips between the blade mounting group and moldboard can be easily adjusted and replaced. Shimless Moldboard Retention System uses vertical and horizontal adjusting screws to keep moldboard wear strips aligned for reduced blade chatter and precise blade control.
Blade Angle and Moldboard
Aggressive blade angle allows material to roll more freely along the blade for better material control. Heat-treated rails, hardened cutting edges and end bits, and heavy duty bolts to give you greater moldboard reliability and long service life. The 5-position link bar allows extreme moldboard positioning for easier bank sloping and ditch cutting/cleaning.
Comfort and Control
Experience the most spacious, comfortable cab in the industry. Simple, intuitive joystick controls replace conventional levers, steering wheel and transmission control handle so hand and arm movement is reduced by 78%, helping to reduce operator fatigue. Rocker switches and control levers are in easy reach. A standard Cat Comfort Series suspension seat and electronically adjustable control pods add even more to comfort and productivity. Multiple isolation mounts significantly reduce sound and vibration for a more relaxed work environment. The high capacity Heating, Ventilation and Air Conditioning (HVAC) system dehumidifies and pressurizes the cab, circulates fresh air, seals out dust and keeps windows clear. A standard cage fan and dual pop-out louvers help improve fresh air circulation too. An optional deluxe radio with CD features MP3 and Bluetooth technology.
Good visibility is key to your safety and efficiency. Large windows make it easy to see the moldboard and tires, as well as behind the machine. A rear vision camera is available to enhance your sight lines to the rear of the machine and an optional anti-icing window feature will help keep windows clear during cold and snowy conditions.

Speed Sensitive Steering
Standard function makes steering less sensitive as ground speed increases for greater operator confidence and control.
Secondary Steering System
Standard system automatically engages an electric hydraulic pump in case of a drop in steering pressure so the operator can steer the machine to a stop.
Disables all implement functions while still providing machine steering control. This standard safety feature is especially useful while roading.
Brakes at each tandem wheel eliminate braking loads on the power train. Redundant brake systems utilize accumulators to enable stopping in case of engine failure.
Walkways and Grab Rails
Perforated steel tandem walkways and convenient grab rails offer a sturdy platform and support for moving on, off and around the machine.
An optional rear vision camera with in-cab monitor helps enhance your sight lines to the rear of the machine.
Circle Drive Slip Clutch

The Cat “Live Spindle” design places the larger tapered roller bearing on the outside, where the load is greater, extending bearing life. A bolt-on modular rear axle improves serviceability and contamination control with easy access to differential components.
Oil-bathed multi-disc service brakes are hydraulically actuated for smooth, predictable braking and lower operating costs. Brakes are located at each tandem wheel for a large total brake surface area to give you dependable stopping power and longer life.
Steering and Implement Controls
Two electro-hydraulic joysticks with electronically adjustable control pods help position operators for optimal comfort, visibility and productive operation.
The left joystick controls steering, articulation (with standard push-button return-to-center feature), wheel lean, gear selection and directional control, and left moldboard lift cylinder (with standard float capability). The right joystick controls drawbar, circle and moldboard functions as well as right moldboard cylinder (with standard float capability). It also houses the electronic throttle control and manual differential lock/unlock. The steer tire angle mirrors the joystick lean angle or position, providing similar feel to steering. A brake tensioning system holds the joystick in position until the operator moves it. The steering control automatically reduces steering sensitivity at higher ground speeds. A Programmable Auxiliary Hydraulic Pod controls up to six additional hydraulic circuits.
Electronic Throttle Control
Operators get precise and consistent throttle operation, with automatic/manual modes that allow you to adjust for application and operator preferences.
Automatically returns the machine to a straight frame position from any angle with the touch of a button.
Selectable Blade Lift Modes
Choose the blade lift modulation mode that best fits your application or operating style: Fine, Normal, or Coarse.
A proven load-sensing system and advanced electro-hydraulics give you superior implement control and responsive hydraulic performance to make your operator's job easier. Continuously matching hydraulic flow/pressure to power demands creates less heat and reduces power consumption.
- Proportional Priority Pressure-Compensating (PPP-C) valves have different flow rates for the head and rod ends of the cylinder, so you can count on consistent, predictable implement response.
- Hydraulic flow is proportioned to give you confidence that all implements will operate simultaneously without slowing the engine or speed of some implements.
Allows the blade to move freely under its own weight. By floating both cylinders, the blade can follow the contours of the haul road. Floating only one cylinder permits the toe of the blade to follow a hard surface while the operator controls the slope with the other lift cylinder.
