The EDCO 69100 Crete-Planer 10" Walk-Behind Scarifier is the gas-powered concrete preparation tool that contractors reach for when grinding alone is too slow and a milling machine is overkill. Powered by a Honda GX390 13 HP gas engine, this 10-inch single-drum scarifier removes 500 to 700 square feet per hour at 1/8" depth per pass, making it the right size for sidewalk repair crews, parking-deck restoration teams, and concrete contractors who need real production without dragging a tow-behind onto the job.
Built for these jobs
Concrete and asphalt contractors use the CPM-10-13H to fix curled control joints and trip hazards on sidewalks, level high spots before patching, knock down popcorn finishes, remove paint stripes and traffic markings from parking lots, take off thermoplastic and elastomeric coatings from interior floors, groove ramps and walkways for traction, and prep slabs before applying epoxy or polished-concrete systems. The aggressive cutting action shears material away rather than dust-grinding it, which is why crews choose a scarifier over a grinder when they need to remove thicker buildup or correct surface elevation in fewer passes.
Construction and serviceable design
The frame is fabricated from 1/4" steel and rides on heavy-duty oversized bearings, so the machine takes a beating on rough subgrade without flexing or wallowing out. With cutters in place the unit weighs 299 lbs, which is heavy enough to hold the cut without bouncing yet still movable on the larger 6" rear wheels EDCO uses for transport. A tethered emergency stop switch is standard, and the side-loading drum design lets a single operator change between 6-shaft and 8-shaft tungsten-carbide cutter assemblies without breaking down the chassis. A standard vacuum port accepts most contractor-grade dust collectors so the operation can run nearly dust-free indoors or on tight-tolerance jobs.

Frequently asked questions
What is the difference between a scarifier and a grinder?
A scarifier uses rotating cutter assemblies that chip and shear material from the surface, removing 1/16" to 1/4" per pass. A grinder uses diamond segments that abrade the surface and remove much less per pass. Scarifiers are faster for thick coatings and elevation correction. Grinders are better for fine polishing and final smoothing.
Can this remove epoxy and elastomeric coatings?
Yes. The CPM-10 is one of the standard tools for thick-coating removal on warehouse, industrial, and parking-deck floors. Match the cutter type to the coating: tungsten-carbide cutters for most paints, epoxies, and thinset; beam cutters for thicker rubberized coatings.
Does it run dust-free?
Connect the standard vacuum port to a HEPA dust extractor sized for at least 250 CFM and the operation runs nearly dust-free, which is now standard practice for OSHA silica compliance on indoor concrete prep.
How deep can it cut in one pass?
Depth is operator-controlled. Most contractors take 1/8" per pass for production scarification. The machine can take more in soft material, but multiple shallow passes give a flatter finished surface than one deep pass.
What blade or cutter does it accept?
The CPM-10 uses 6-shaft and 8-shaft side-loading drums populated with tungsten-carbide cutters, beam cutters, or milling cutters. EDCO and aftermarket suppliers stock replacement assemblies; swap takes a few minutes with hand tools.
