Description
Pavement contractors lose project profits when underpowered push saws bog down in aggregate, so step up to the Edco SS-20 Gas Self-Propelled Saw. This commercial machine turns twenty-inch diamond blades to plunge eight inches deep into asphalt and concrete. A Honda engine drives the arbor. You must adjust hydrostatic forward crawl rates to match blade resistance.
Edco fabricates the rigid chassis from heavy seven-gauge welded steel plate to prevent frame twist under load. A 20 HP Honda GX630 V-twin gas engine drives the 1.75-inch blade arbor through a multi-band V-belt system at 2400 RPM. Unboxed machine weight totals 575 lbs. Frame dimensions measure 48 inches long by 28 inches wide by 40 inches high with an integrated hydrostatic drive transmission.
Key Features of Edco SS-20
Road paving crews buy Edco SS-20 gas saws to cut highway relief lines while tracking commercial equipment pricing online. Concrete cutting contractors slice cured slabs and asphalt roads without suffering engine stall or operator pushing fatigue.
- Honda GX630 20 HP engine delivers continuous high torque through dense stone aggregates.
- Twenty-inch blade guard clears eight-inch deep single-pass cuts in pavement.
- Hydrostatic transmission powers forward travel without manual push effort from the operator.
- Heavy seven-gauge steel chassis resists frame flex when plunging through steel reinforcement rebar.
- Dual water spray nozzles feed both blade sides to cool segments and flush cuttings.
- Screw feed depth control gives positive manual blade elevation adjustment without hydraulic drift.
- Cast iron pillow block arbor bearings support the blade shaft against violent shock loads.
Arbor Concentricity Hydrostatic Load Tolerances
Bench load testing confirms rigid arbor concentricity under sustained full-depth cutting runs. Blade arbor runout measures under 0.0011 inches TIR at the blade mounting collar shoulder. Under seven-inch plunge cuts through four-thousand-PSI limestone concrete, the Honda GX630 engine holds 3400 RPM with governor drop staying under four percent. Arbor pillow block bearing housing temperatures stabilize at 140 degrees Fahrenheit after three hours of non-stop trench sawing. The hydrostatic crawl drive maintains steady tracking along straight chalk lines without surging.
Roadway Operation Field Maintenance Realities
Guiding this 575-pound saw along roadway chalk lines feels balanced on rough pavement, with the hydrostatic lever offering smooth crawl speed adjustments through thick leather gloves. The forward pointer arm tracks true without lateral play. Do not buy this gas-powered saw for indoor building slabs lacking high-volume auxiliary scrubbed ventilation systems.
- Grease the blade arbor pillow block bearings through grease zerks every shift.
- Check tension on the multi-rib drive belts every forty operating hours.
- Clean the dual-element Honda engine air cleaner foam pre-cleaner every twenty hours.
