Overview
More Power to Get the Job Done
The PM820 is a high-production half-lane milling machine with a cutting width of 2010mm (79.1in) that performs controlled full-depth removal of asphalt and concrete pavements in a single pass.
AdvantagesMilling Precision
Get perfect cuts with integrated technology, K-system rotors, and Cat pattern design with advanced steering and traction control.
Maximum Power
Automatic features optimize demand on the engine and rotor system to maintain smooth and productive operation, providing up to 27% more power compared to the PM620 and PM622.
Better Maintenance
Specially designed to reduce your maintenance time with direct access to critical components, extended maintenance intervals, and high parts availability, combined with engine and machine support from your Cat dealer.

Powerful Performances
Powerful dual turbocharged C18 CAT® engine compliant with regional emissions standards Flexibility and efficiency of operation thanks to automatic idle control and different rotor speeds optimize engine power and stress High-capacity cooling system maintains the engine at the ideal temperature for reduced emissions and optimal energy efficiency Automatic load detection on the rotor adjusts milling speed to prevent stalling and optimize production
Optimal Maneuverability and Control
The reliable chain undercarriage takes advantage of the proven designs of Cat dump trucks and an automatic tensioning system to ensure consistent performance and longer chain life. The robust propulsion system includes two independent travel pumps that drive two chain tracks each, according to a high-traction cross-drive scheme. Thanks to the automatic traction control, speed remains constant in the most challenging applications. Four steering modes with advanced alignment and tracking ensure precise control of geometry and reduce wear on the pads. Ability to change rotor speeds electronically during operation.
Material Removal
High-capacity conveyors provide efficient removal of milled material with incredible dumping control. A single-piece and wide-opening conveyor belt effectively empties the rotor chamber. Adjust the speed of the conveyor belt according to the type of material and production flow, while the integrated boost functionality offers temporary acceleration of the conveyor belt speed to eject the material faster and farther. The direction of the conveyor belt can be reversed for easy cleaning, and vinyl magnetic protections allow quick access to inspect roller wear.
A comfortable working environment
Use in total comfort with adjustable height consoles and intuitive and ergonomic controls Retractable handrails that retract when approaching obstacles, then easily redeploy Work day and night with backlit keyboards and illuminate the work area around the machine with extended perimeter LED lighting options Optimize driving positions with optional suspension seats that are repositionable for improved visibility and comfort Optional remote cameras improve visibility on the cutting blade and conveyor The option of an electric roof that closes forward and has a single pillar with high LED lighting and integrated side extensions retracts and deploys quickly during use with a simple button to avoid overhead obstacles, and an optional windshield can be added for improved comfort Maximize dust elimination in work areas with the optional dust reduction system
Durable cutting system
The rotor drive system includes an extra-strong dry clutch, an automatic belt tensioning system to prevent slipping, and two high-strength belts (with five ribs) to drive the rotor. Reinforced cutting chamber for longer life. Improved access simplifies rotor replacements. Full-length side plate hardened skis, onboard ski pad, and anti-fracture pads reduce wear and maintenance.
Rotors System
The K System Cat rotors ensure efficient material flow with an excellent cutting profile for many applications. Conical design with double retention securely locks the tool holders in place without a retention axis, bolt, or adjustment screw for faster replacement without attachments and without torque tightening. Reversible blades and ultra-resistant alloys reduce wear and abrasion, for increased rotor lifespan. Optional diamond tips allow for replacement intervals up to 80 times longer than traditional carbide tips.
Easy Maintenance
Maintenance is simplified and faster thanks to large access doors and an electric hood that provides very easy access to crucial components. Maintenance-free chain components and easy-to-replace chain pads reduce maintenance costs. Standard ground-level controls and an optional hydraulically operated rotor rotation device with suspended control simplify the removal and replacement of tips. Optional high and low-pressure washing options connect to the onboard water tank for convenient cleaning. Use certain machine functions during maintenance and servicing thanks to the auxiliary drive system. The electrical circuit wiring is color-coded and numbered for easy identification. It is also protected by an abrasion-resistant nylon braid, ensuring increased lifespan. Extended hydraulic oil maintenance intervals: 3,000 hours without oil sampling, 6,000 hours with oil sampling. Planned chain maintenance with Cat Product Link™ telematics services. Electronic Control Modules (ECMs) monitor machine circuits to alert the operator of performance issues. They can be paired with Product Link options to activate additional remote services from your local Cat dealer. Environmentally friendly, multi-component cartridge engine filters reduce waste and lower replacement costs. Optimal parts availability, conveniently located dealers, and maintenance repair kits simplify ordering of high-wear components.
Convenient features
