When it comes to cold planers HCN seem to be able marry quality and cost. Rugged, solid, super reliable, powerful, if your machine can provide the flow we put these units against any of their Western piers.

1. Overview

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.


2. Types of Cold Planers

TypeDescription
Standard Width PlanerFixed-width cutters (12″, 16″, 18″, 24″, 40″, etc.).
High Flow ModelsDesigned for machines with high hydraulic capacity; deeper cuts, higher RPM.
Tilt/Side Shift PlanersEquipped with side shift and tilt for precise alignment along curbs, walls, or grade slopes.

3. Key Components

ComponentFunction
Cutting DrumRotating drum with carbide teeth that mills the surface.
Hydraulic MotorPowers the drum using auxiliary flow from the skid steer.
Side Shift MechanismAllows lateral movement for edge milling.
Tilt CylinderAdjusts vertical pitch for sloped or variable-depth cutting.
Depth Control SkidsSet maximum cutting depth and stabilize operation.
Mounting PlateUniversal Quick Attach plate for skid steer connection.

4. Compatibility

4.1 Mounting

  • Standard: Universal Skid Steer Quick Attach
  • Mini Loaders: Not compatible due to size/weight

4.2 Hydraulic Requirements

Planer TypeFlow Rate (GPM)Pressure (PSI)Note
Standard Flow Planers13–22 GPM2,500–3,000 PSILight to moderate use
High Flow Planers24–40+ GPM3,000–4,200 PSIRequired for deeper milling

✅ Check your skid steer’s auxiliary flow rating before purchase.


5. Operating Instructions

5.1 Setup

  1. Attach the planer to the skid steer via the quick attach plate.
  2. Connect hydraulic hoses to auxiliary ports.
  3. Purge air by engaging hydraulics briefly at low RPM.
  4. Set cutting depth using manual or hydraulic skid adjustments.

5.2 Operation

  1. Start milling with the planer aligned and level to the surface.
  2. Use slow, steady forward motion (~1–3 ft/min) to ensure smooth cut.
  3. Engage side shift and tilt functions (if equipped) for precision edge work.
  4. Monitor drum RPM and engine load; avoid overloading the motor.
  5. Clear debris with a sweeper or bucket post-milling.

6. Safety Guidelines

  • Always wear PPE: hearing protection, eye protection, gloves.
  • 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.

7. Maintenance Checklist

TaskFrequency
Inspect carbide teeth for wearEvery use
Torque drum boltsWeekly
Grease tilt and shift cylindersEvery 10 hours
Check hydraulic hoses/fittingsDaily
Clean debris from housingAfter each use
Replace worn teethAs needed

Max Cutting Depth~4″6″–8″+
RPM Range100–200200–400+

9. Use Cases

  • Asphalt Repair: Cutting for pothole patches or overlay prep
  • Concrete Milling: Removal of surface imperfections
  • Trenching: Creating utility cuts
  • Leveling: Smoothing high spots for resurfacing

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.

12. Conclusion

Cold planer attachments allow skid steer loaders to take on serious surface removal and milling work typically reserved for dedicated machines. By selecting the proper planer size, matching your hydraulic specs, and maintaining the attachment well, you can dramatically increase your jobsite productivity and precision.
