Interior

Power Train

Smooth Shifting Transmission -

Full Electronic Clutch Pressure Control ensures smooth shifting and directional changes.
Shift Torque Management helps to smooth gear changes without the use of the inching pedal, helping the operator to remain focused on the task at hand.
Load Compensation ensures consistent shift quality regardless of blade or machine load.
Optional Autoshift automatically shifts the transmission at optimal points for easier operation.

Oil Disc Brakes - Completely Sealed, Adjustment Free - Oil-bathed, air actuated and spring-released, located at each tandem wheel to eliminate power train braking loads and to reduce service time. The large brake surface area provides dependable braking capability and extended life before rebuild.

Front Axle with Cat Live Spindle Design - Cat sealed spindle keeps the bearings free from contaminants and lubricated in a lightweight oil to reduce owning and operating costs. A larger tapered roller bearing is outboard where the load is greater, extending bearing life.

Cat C7 Engine

Power Management - The Cat C7 engine with ACERT Technology uses electronic control, precision fuel delivery and refined air management to provide outstanding performance and lower emissions. Variable Horse Power (VHP) is standard to provide more power in the higher gears. The Electronic Throttle Control provides easier, more precise and consistent throttle operation. Engine Over-Speed Protection prevents downshifting until an acceptable safe travel speed has been established.

Hydraulics

Balanced Flow, Independent Oil Supply - Hydraulic flow is proportioned to ensure all implements operate simultaneously. Independent oil supply prevents cross-contamination and provides proper oil cooling, which means less heat build-up and extended component life.

Implement Control Valves - Provide outstanding operator “feel” and predictable system response for unmatched implement control. To help maintain exact blade settings, lock valves are built into all control valves. Line relief valves are also incorporated into selected control valves to protect the cylinders from over pressurization.

Load-Sensing Hydraulics - A load sensing variable displacement pump and advanced hydraulic valves provide superior implement control and better machine performance. Continuously matching hydraulic flow and pressure to power demands creates less heat and reduces power consumption.

Consistent and Predictable Movement - The hydraulic system valves are specifically designed for each hydraulic function on the motor grader. They compensate for differences in flow requirements, based on cylinder size and the difference in surface volume between the rod end (blue) and barrel end (red) of the cylinder. The result is predictable, consistent hydraulic speeds whether extending or retracting the cylinder.

Structures/Drawbar-Circle-Moldboard

Frame Structure - Provides Consistency and Strength - Front frame is a continuous top and bottom plate construction. Flanged box section design removes welds from high stress areas, improving reliability and durability. The rear frame structure has two box section channels with fully welded differential case for a solid working platform. An integrated bumper ties the rear frame together into a cohesive unit to handle high stress loads.

Drawbar, Circle and Moldboard - The K Series drawbar is designed for high strength and optimum durability for any application. The circle stands up to high stress loads. Raised wear surfaces prevent circle teeth wear against the drawbar. The 64 uniformly spaced circle teeth are flame cut and heat induction hardened to resist wear, and the circle is secured to the drawbar by four support shoes for maximum support. The moldboard provides optimal curvature and large throat clearance that helps move all soil types quickly and efficiently. These features deliver excellent load distribution and minimal material buildup in the circle area while allowing large blade loads to roll freely.

Blade Lift Accumulators - This optional feature uses accumulators to help absorb impact loads to the moldboard by allowing vertical blade travel. Blade lift accumulators reduce unnecessary wear and help to avoid unintended machine movement for increased operator safety.

Work Tools and Attachments

Moldboard Options - Standard moldboard length is 3.7 m (12 ft). Moldboard extensions are available to increase moldboard surface area and extend reach capability.

Ground Engaging Tools - A wide variety of cutting edges and end bits are available, all designed for maximum service life and productivity.

Rear Ripper/Scarifier - The K Series optional ripper/scarifier is made to penetrate tough material fast and rip thoroughly for easier material movement with the moldboard. The ripper includes three shanks with the ability to add two more if needed.

Front Mounted Groups - A front mounted push plate/counterweight or front blade can be ordered.

Mid-Mount Scarifier - Positioned between the front axle and the circle to break up tough material that the blade can then move, all in a single pass. The V-type scarifier can accommodate up to 11 teeth.

Snow Removal Work Tools - Includes snow wings, angle blades, and V-plows. Multiple mounting options are available, increasing machine versatility. (Availability may differ by region.)

Operator Station

Designed for Productivity - K Series cabs are designed to keep operators comfortable, relaxed and productive. Features like low effort pedals and controls, adjustable implement controls and adjustable steering wheel angle help make work easier on the operator. A clear view to the moldboard heel and tandem tires enhance productivity and safe operation. Rocker switches and transmission shifter are backlit for night time operation.

In-dash Instrument Cluster - The instrument panel, with easy-to read, high-visibility gauges and warning lamps, places vital machine information and diagnostic capability in easy view of the operator. The dash includes an engine coolant temperature gauge, an articulation gauge, voltage gauge and fuel level gauge. Service brake air pressure gauges are also standard. Speedometer and tachometer are optional. All major systems are monitored by warning lights.

Additional cab features include storage area, an adjustable control console and coat hook. Optional offerings include power port, air conditioner/heater, suspension seat, defroster fan, sun shade, backup lights, Product Link™ ready, and AccuGrade™ System ready. NOTE: Some attachments are not available in all regions.

Integrated Technologies

Cat AccuGrade - AccuGrade uses positioning and guidance technologies, machine sensors, and automatic blade control to help operators get to grade faster, easier and more efficiently. Digital design plans, real-time cut/fill data, and in-cab guidance give operators detailed information to work more confidently and achieve greater accuracy, in fewer passes, using less material. Operators can stay on grade and improve productivity and accuracy by nearly 50 percent over conventional methods. Grade stakes and checkers are minimized, making the work site safe, efficient, and cost effective. AccuGrade technologies include Cross Slope, Sonic, Laser, GPS, and/or Universal Total Station (UTS).

AccuGrade Attachment Ready Option (ARO) - K Series machines can be equipped with the AccuGrade ARO. It can be ordered as a factory or dealer installed option. The attachment option includes built-in mounting points and internal wiring, making installation of the AccuGrade grade control system faster and easier.

Cat Product Link - Product Link helps take the guesswork out of equipment management with remote monitoring capabilities for your machine or your entire fleet. Track asset location, hours, fuel usage, diagnostic codes, idle time and more through the secure VisionLink™ user interface. Knowing where your equipment is, what it's doing and how it's performing enables you or your Cat dealer to manage your fleet in real-time so you can maximize efficiency, improve productivity, and lower operating costs.

Safety

ROPS/FOPS Cab Offers Low Sound and Vibration Levels - The operator sound pressure level for the cab offered by Caterpillar, when properly installed, maintained and tested with the doors closed, meets or exceeds requirements set forth in ISO 6394:2008. The quiet environment helps improve operator working conditions.

Brake Systems and Machine Protection - Brakes located at each tandem wheel offer the largest total brake surface area in the industry, delivering dependable stopping power and longer brake life. Standard circle drive slip clutch protects the drawbar, circle and moldboard from shock loads when the blade encounters an immovable object. Blade lift accumulators help absorb impact loads to the moldboard by allowing vertical blade travel.

Electrical Disconnect Switch and Engine Shutoff Switch - Disconnect switch provides ground-level lockout of the electrical system to prevent inadvertent machine starts. Engine shutoff allows anyone nearby to shut the machine down in case of an emergency.

Laminated glass on the front windows and lockable doors to reduce theft and vandalism are available with the optional cab. Brake lights, conveniently located grab rails, back up lights and alarm also help ensure a safe work environment.
