The EDCO SS-20-20H, ordered as part 32600, is a 20-inch self-propelled walk-behind concrete saw with a 20 HP gasoline engine. It is built for concrete contractors, paving crews, municipal public-works teams, and demolition subs who cut expansion joints, score slabs for removal, and prep utility trenches. Self-propelled drive, an electric-start 12-volt system, a stressproof precision-machined steel arbor shaft, and a screw-type depth lock are the operator-side features that separate the SS-20-20H from the entry-level push class.
Use cases
Expansion joint cutting
General contractors and concrete subs cut control joints in poured slabs at the right time after the pour. The SS-20-20H is sized for industrial slab work, dock pads, and parking-deck pours where joint length and cut depth both matter.
Utility-trench layout cutting
Municipal and underground crews score the slab on either side of a planned trench with the 20-inch blade so the breaker takes a clean break instead of fragging the surrounding concrete.
Slab removal and demolition prep
Concrete demolition crews use the saw to outline a slab section for breakup and disposal. A clean perimeter cut keeps the surrounding slab intact and reduces patch volume.
Decorative scoring and asphalt patch
Decorative concrete crews use the saw to drop in score patterns. Paving contractors cut asphalt for patch repairs, manhole adjustments, and water-main work.

Frequently asked questions
How deep can the SS-20-20H cut?
With a 20-inch blade the saw cuts roughly 7 inches deep, which covers the vast majority of slab and pavement work, including most expansion joints, slab removal scoring, utility-trench layouts, and decorative score lines. The screw-type depth control with lock keeps that depth honest pass after pass.
Why specify a self-propelled saw over a push saw at this size?
At 20 inches and 20 HP the cutting load and the saw weight together are too much to push a straight, even line for hours. Self-propelled drive paces the cut, lets the operator focus on tracking the chalk line, and reduces fatigue on long runs. Most concrete contractors who run a saw daily will not buy a 20-inch class saw without self-propulsion.
What blade should I use on hard rock and rebar?
Match the blade to the aggregate. Hard-aggregate slabs (granite, basalt, river rock) cut cleaner with a hard-bond diamond blade rated for hard concrete. Soft-aggregate slabs (limestone, sandstone) need a softer-bond blade. Rebar-loaded slabs ask for a reinforced-concrete blade. The factory blade flange and arbor accept the standard 20-inch concrete-saw blades from the major diamond manufacturers.
Does the saw need water during the cut?
Yes. Wet cutting is standard at this class for blade life, dust suppression, and silica compliance. The saw is plumbed to accept a water feed at the blade guard. Plan for a continuous water source on site or a portable water tank with a feed line.
Is there a CARB issue I should know about?
Honda and Vanguard 20 HP gas engines built for this class typically meet the EPA standard but state-specific emissions rules can apply. Confirm CARB compliance against the unit's serial number before specifying it for a California job; the dealer team can pull the engine paperwork.
Discount Cleaning Products is an authorized EDCO dealer. US-based customer service can confirm engine variant and emissions compliance before a California or municipal job, source the right blade for the aggregate the crew is cutting, and pull the EDCO replacement parts list whenever the saw needs service.
