Husqvarna FS400LV 20-Inch Walk-Behind Concrete Saw

The Husqvarna FS400LV 20-Inch Walk-Behind Concrete Saw is a heavy-duty petrol floor saw engineered for expansion joint cutting, utility trenching, and asphalt patching across road repair construction sites. Powered by an 11.7 HP 4-stroke Honda engine, this walk-behind saw accepts diamond blades up to 20 inches in diameter to deliver a maximum cutting depth of 7.5 inches (189 mm). Outfitted with an optimized weight distribution chassis, a low-vibration height-adjustable handlebar, a retractable handwheel depth adjustment system, a 1-inch arbor, and a 206.3 fluid ounce fuel tank, this 236-pound machine suppresses airborne dust using an integrated water tank assembly.

Best Used For:

  • Asphalt Pavement & Road Repair Patching: Cutting square relief joints in damaged asphalt roadways prior to utility excavation and resurfacing.
  • Concrete Slab Expansion Joint Cutting: Sawing continuous control joints in freshly poured commercial concrete floors and parking structures.
  • Utility Trenching & Pipe Channeling: Sinking deep 7.5-inch parallel kerf cuts into concrete slabs to lay electrical conduit and plumbing lines.

Key Performance & Safety Features

  • 11.7 HP Commercial Honda Gas Engine: Reliable 4-stroke OHV engine delivers continuous rotational torque to handle thick concrete and asphalt slabs.
  • 7.5-Inch Maximum Cutting Depth: Accommodates 20-inch diamond saw blades with a 1-inch arbor for deep slab penetration.
  • Retractable Handwheel Depth Control: Fine-pitch adjustment screw wheel with clear visual scale gauge permits precise blade height control.
  • Ergonomic Height-Adjustable Handlebars: Position-adjustable handle grips reduce arm strain and lower vibration transmission during long cuts.
  • Integrated Dust-Suppression Water Tank: Gravity-fed water delivery system keeps diamond blade segments cool and suppresses airborne silica dust.
  • Balanced Weight-Distribution Frame: Low center-of-gravity steel chassis maintains straight tracking and prevents blade binding inside deep kerfs.

  • (1) Husqvarna FS400LV 20-Inch Walk-Behind Concrete Saw Chassis
  • (1) 11.7 HP Honda 4-Stroke Commercial Gas Engine (Pre-installed)
