Cutting through dense turf on commercial routes, the Husqvarna W520 walk-behind mower delivers cast-aluminum deck durability without rust or corrosion failures. Commercial mowing crews punish walk-behind mowers daily, cracking thin stamped steel decks when striking concrete curbs and stone borders. This 20-inch commercial machine features a heavy cast-aluminum cutting deck, a commercial Kawasaki FJ180V engine, and a blade brake clutch system that keeps the engine running while blade rotation stops.

A commercial-grade gear transmission powers the rear wheels, delivering positive drive traction across damp slopes and rolling commercial lawns. The cast-aluminum deck shell absorbs stone impacts without denting or rusting, maintaining smooth internal airflow for clean grass collection and mulching. An ergonomic handlebar with heavy rubber vibration dampers isolates the operator from engine vibration, keeping hands comfortable through eight-hour commercial trimming shifts.
