The EDCO 61320 is the OEM 6-shaft drum assembly for the CPU-12 walk-behind concrete planer. Sidewalk-trip-hazard contractors, flooring crews stripping coatings and adhesives, and surface-prep teams keep this drum on the parts shelf so a worn cutter shaft is a same-day fix instead of a multi-week downtime. Direct factory fit, holds the standard CPU-12 cutter sets across the full 12-inch working width.
Use cases
Trip-hazard removal
Sidewalk-trip-hazard contractors run the CPU-12 daily. A worn drum slows the cut; replacing the drum returns the planer to spec.
Coating and adhesive removal
Flooring contractors use the CPU-12 to take down coatings, adhesives, and thin overlays before repour. Fresh cutters in a fresh OEM drum keep the cut profile correct for the next coating system.
Concrete surface prep before resurfacing
Restoration crews specify the CPU-12 with a 6-shaft drum for surface prep before decorative overlays.
Rental and fleet operations
Equipment-rental yards and concrete-fleet operations stock spare drums against the next service cycle so a worn drum never returns the machine to the bone yard.

Frequently asked questions
What machine does the 61320 fit?
The 61320 is the OEM 6-shaft drum assembly for the EDCO CPU-12 walk-behind concrete planer. It is sized for the 12-inch working width on that platform.
How does the 6-shaft layout compare to other drum configurations?
EDCO offers the CPU-12 in different shaft counts. The 6-shaft drum is a balance between cutter density and load on the engine and drive system. Higher shaft counts cut more material per pass on a flat slab; lower shaft counts handle uneven surfaces and reduce engine load. Most contractors who run the CPU-12 daily standardize on the 6-shaft layout.
Which cutters are compatible?
The 61320 drum accepts the standard EDCO CPU-12 cutter sets, including tungsten-carbide cutters for hard concrete, beam cutters for trip-hazard removal, and milling cutters for thin coatings. Match the cutter to the work; the dealer team can pull the EDCO compatibility chart.
Is the drum a wear part?
Yes. Cutter shafts wear and the drum body itself wears at the cutter seats over the service life of a CPU-12. Stocking a spare 61320 drum means the second wear cycle is a swap, not a multi-week wait for an OEM replacement.
How is the drum installed?
Drum replacement on the CPU-12 is a workshop job: pull the planer onto a bench, remove the drum housing, swap the assembly, replace the cutters in the right rotation pattern, and reinstall. Field crews who do not service their own machines should send it to a service partner; the dealer team can recommend one.
Discount Cleaning Products is an authorized EDCO dealer. US-based customer service can confirm the right drum and cutter pairing for the work the CPU-12 is doing, route warranty claims through EDCO, and source the rest of the CPU-12 wear kit (bearings, belts, drive components) when the planer is in for full service.
