Caterpillar has made several updates to its lineup of cold planers.
The enhancements apply to Cat’s PM620, PM622, PM820, PM822 and PM825 half-lane cold planers.
The milling machines now meet Tier 4 Final and EU Stage V emission standards, powered by a Cat C18 turbocharged, 6-cylinder diesel engine.
The PM820, PM822 and PM825 cold planers feature an increased power rating of 800.6 hp gross power. The engine also now features multi-piece, cartridge-style filters. This design is environmentally friendly, reduces waste and lowers replacement costs.
Cold planer productivity
Updated handrails increase operator comfort and ease-of-use in flush cutting applications. As well, the new pivoting handrails stow and redeploy easily on the right-hand side when an obstacle comes close to the machine. Obstacle jump is easier to execute from the operator platform with new visual indicators that are positioned on the top edge of the side plates indicating where the rotor is positioned and correlates with the markings on the side plate.
Enhancements also include an updated track pin design. A lower pin location increases tractive effort and force on the undercarriage when milling in deep or hard applications.
New hardened steel bolt-on wear skis run the full length of side plates and a wear shoe on the anti-slab assembly reduce wear and maintenance.
K Rotors for cold planers
Cat’s cold planers are available with the Cat System K milling rotors and feature efficient material flow with an improved cutting pattern. The rotors are available with spacings of 8 mm, 15 mm and 18 mm for a wide range of milling applications.
The dual taper retention design provides a reliable method for holding the tool holders in the blocks without the need for a retaining pin or bolt. Furthermore, reversible paddles and high strength alloy offers more resistance to abrasion and reduce wear for extended rotor life.
Optional Cat diamond bits feature a new design for the System K rotors and last as much as 80 times longer than conventional carbide bits to extend intervals between maintenance.
Cat diamond bits are sharper than conventional carbide bits, according to the manufacturer, allowing the machine to cut faster and to reduce drag on the cutting system for improved fuel economy in demanding applications.

The PM620, PM622, PM820, PM822 and PM825 cold planers are capable of performing controlled full-depth removal of asphalt and concrete pavements in a single pass.
A variety of options, including the integrated Cat Grade Control system, may be installed to customize the machine.
