The EDCO DS-20 is a 13 HP Honda-powered, downcut walk-behind concrete saw built for contractors cutting slabs, control joints, patch repairs, and trenches. Downcut blade rotation pulls the blade into the slab for fast, straight cuts with minimal surface chipping - the reason flatwork and concrete crews choose a self-propelled-style walk-behind over a handheld cut-off saw for production work.
Built for
- Concrete and flatwork contractors - straight, deep cuts in slabs, driveways, and sidewalks.
- Control and contraction joints - clean, consistent joint cutting to manage slab cracking.
- Patch and repair crews - square out damaged concrete for patching and resurfacing.
- Trenching and utility work - cut access lines and trenches in cured concrete.
Downcut design, 7.75-inch depth
A 13 HP Honda engine spins a 20-inch blade at 3,000 RPM for up to 7.75 inches of cut depth. The downcut rotation drives the blade down into the work for fast, straight cuts with less surface damage, while a heavy-duty 7-gauge laser-cut steel frame and anti-vibration engine mount keep the saw tracking true. A large screw-type depth control and easy-turn crank raise and lower the blade smoothly in and out of the cut, and wide-T handles with rubber grips give the operator control all day.

Frequently asked questions
What is the difference between a downcut and an upcut saw?
Downcut rotation pulls the blade down into the slab, which produces fast, straight cuts with minimal chipping and throws debris forward away from the operator. It is preferred for clean joint and slab cutting.
How deep can the DS-20 cut?
With a 20-inch blade it cuts up to 7.75 inches deep, enough for most slab, joint, and repair work in a single pass setup.
What blade does it take?
It has a 20-inch dual-arbor blade capacity. Choose a diamond blade matched to the material - cured concrete, green concrete, or asphalt - for best life and cut speed. Blades are sold separately.
Is it stable enough for straight cuts?
Yes. The 265-pound machine, 7-gauge laser-cut steel frame, and anti-vibration engine mount keep it tracking straight, while the screw-type depth control sets a precise, repeatable depth.
What jobs is the DS-20 best for?
Slab cutting, control and contraction joints, patch and repair cut-outs, and trenching in cured concrete - production tasks where a handheld saw would be slow and less accurate.
