The Scag SWZ Hydro-Drive Walk-Behind Mower


Scag SWZ The Scag SWZ Zero Turn Walk Behind Mower is the only choice for professional cutters like you.

Its outstanding quality, dependability and performance will put you a step ahead of your competition.

Dual hydraulic pumps and cast-iron wheel motors allow independent, positive power to each wheel. With counter-rotation turning, one wheel moves forward while the other moves backward, minimizing scuffed turf and increasing maneuverability in heavily landscaped areas.

With our exclusive Advantage™ and Velocity Plus™ cutter decks, you will get the perfect cut, the first time, every time. Ultra-heavy duty construction and great features like an integrated parking brake set the SWZ apart from the competition.

Scag Walk-Behind mowers are known the world over for being incredible durable and built to last a long, long time. This is not your average walk-behind...it's a Scag.
