Efficiency and Productivity
Delivering the efficiency and productivity you demand through integrated machine systems.
The Autoshift mode, when active, allows the machine to automatically upshift or downshift based on machine speed and torque, optimizing performance and thus saving fuel. This feature can be easily enabled or disabled on the soft keypad.
The left pedal acts as a brake, transmission neutralizer and an engine decelerator to override the engine speed selected by the throttle lock. This enables the operator to slow down when the throttle lock is engaged and to return to throttle lock without pressing a resume or set button again. This aids in maneuvering around trucks, tractors or any other obstacle.

Tamping Wheels and Tips
The heart of any compaction system.
Chevron Tamping Tip Design
The modified chevron tamping wheel tip design provides greater ground pressure, more compaction, excellent traction and a smooth ride.
Compaction is achieved from the bottom of the lift to the top. The tapered tips walk out of the lift without “fluffing” the soil. The top of the lift is compacted and the surface is relatively smooth and sealed so hauling units are able to maintain a high speed when traveling over the fill. The 825K travel speed allows four forces of compaction: pressure, manipulation, impact and vibration. Since the 825K can also spread fill, the number of spreader tractors may be able to be reduced.
Standard tips are used in typical soil compaction applications where compaction specification requirements are 95-100 percent Standard Proctor.
Symmetrical Tamping Tip Pattern
Equal compaction in forward or reverse is the result of the symmetrical tamping tip pattern. Tips are full perimeter and replaceable. The tip is welded to a base assembly, which then is welded directly to the drum.
Each wheel has two cleaner bars to keep the drums free of carryover dirt, regardless of rolling direction so efficiency is maximized.
Adjustable Cleaner Bar Tip
The adjustable cleaner bar tips are heat-treated and direct hardened, cutting edge steel to increase wear life, which translates into lower operating costs.

Monitor, manage, and enhance job site operations.
Cat Connect makes smart use of technology and services to improve your job site efficiency. Using the data from technology-equipped machines, you’ll get more information and insight into your equipment and operations than ever before. Cat Connect technologies offers improvements in these key areas: Equipment Management – increase uptime and reduce operating costs. Productivity – monitor production and manage job site efficiency. Safety – enhance job site awareness to keep your people and equipment safe.
COMPACT technologies combine advanced compaction measurement, in-cab guidance and reporting capabilities to help you consistently meet compaction targets fast, uniformly, and in fewer passes – saving on fuel and the cost of unnecessary rework.
Cat Compaction Control
The factory Cat Compaction Control system uses Machine Drive Power (MDP) technology to measure rolling resistance and correlates it with soil stiffness. MDP works in both cohesive or granular soils. Optional 3D mapping system maps compaction measurements to the precise location the operator is working, providing a real-time view of progress, and a record of compaction uniformity.
LINK technologies wirelessly connect you to your equipment, giving you valuable insight into how your machine or fleet is performing so you can make timely, fact-based decisions that can boost job site efficiency and productivity.
Product Link is deeply integrated into your machine, giving you access to timely information like machine location, hours, fuel usage, idle time and event codes via the online VisionLink user interface can help you effectively manage your fleet and lower operating costs.
DETECT technologies help keep people and equipment safe by enhancing operator awareness of the work area around working equipment and by monitoring and reporting unsafe conditions, like avoidance zones.
Rear Vision Camera
The standard rear vision camera greatly enhances visibility behind the machine to help the operator work more productively. Work with greater confidence and at peak potential while keeping people and assets safe.
