The Husqvarna FS520 20-Inch Walk-Behind Self-Propelled Concrete Floor Saw is a heavy-duty industrial cutter engineered for expansion joint sawing, utility trenching, and asphalt pavement patching. Driven by an 11.7 HP four-stroke Honda gas engine with a hydrostatic differential transmission delivering up to 80 feet per minute forward speed, this floor saw accommodates 20-inch diamond blades to achieve a maximum cutting depth of 7.7 inches (195.58 mm). Outfitted with IntelliSeal spindle bearings for up to 500 hours of maintenance-free operation, low-vibration height-adjustable handlebars, a gas-assisted raise and lower system, a 1-inch arbor, and a water mist dust suppression system, this 493-pound machine executes straight kerf cuts in concrete and asphalt slabs.

Best Used For:

  • Asphalt Pavement & Roadway Patching: Executing deep 7.7-inch relief cuts through asphalt overlays prior to utility excavation and road resurfacing.
  • Industrial Concrete Slab Joint Sawing: Cutting continuous expansion control joints across commercial warehouse concrete floors and parking decks.
  • Utility Trenching & Cable Channeling: Sinking parallel kerf cuts into cured concrete foundation slabs to route drainage pipes, conduit, and utility cables.

Key Performance & Safety Features

  • 11.7 HP Commercial Honda Engine: High-output 4-stroke gas engine provides continuous power to drive 20-inch diamond blades through dense aggregate.
  • 7.7-Inch Maximum Cutting Depth: Deep-capacity blade guard and 1-inch arbor accept large diamond blades for deep slab penetration.
  • Hydrostatic Self-Propelled Drive: Differential drive transmission provides smooth speed control up to 80 fpm to minimize manual operator pushing force.
  • IntelliSeal Blade Spindle System: Patented spindle bearings eliminate daily greasing and protect internal components for up to 500 operational hours.
  • Gas-Assisted Raise & Lower Assembly: Pneumatic spring assists blade depth positioning to simplify blade height adjustments during active cutting.
  • Vibration-Damped Adjustable Handlebar: Ergonomic handle dampens operational vibrations and adjusts to maintain proper operator posture.
