1. Overview
A cold planer attachment (also known as an asphalt planer or milling head) is a hydraulically powered tool that mounts to a skid steer to mill and remove concrete or asphalt surfaces. It’s commonly used for pavement repair, utility cuts, and surface leveling.
Inspect hydraulic lines for leaks or damage before operation.
Never stand near rotating drum.
Disengage hydraulics and shut off machine before performing maintenance.
Be aware of flying debris and use deflectors or guards.

10. Selection Tips
Match cutting width and depth to your job type (patch repair vs. trenching).
Choose a high-flow model if your skid steer supports it and you need aggressive cuts.
Confirm your hydraulic coupler type (flat face, case drain, etc.).
Look for replaceable tooth systems for easy maintenance.
