This mower is built like a tank. The aluminum deck is sturdy, and the variable-speed drive lets me adjust to my pace. My only gripe is the weight; it’s a bit heavy, but the performance makes up for it.

The W520’s self-propelled system is smooth, and the ergonomic handle reduces strain. However, the 112 lbs weight can be cumbersome on slopes. Still, it handles well on flat terrain

As a professional landscaper, I need reliable equipment. The W520 delivers. The Blade Brake Control is a game-changer, allowing me to stop the blade without shutting off the engine. Makes moving between yards so much quicker

The Husqvarna W520 is a beast. The Kawasaki engine starts on the first pull every time. I mow my half-acre lawn with ease, and the mulching feature leaves a clean, even cut. Worth every penny

The W520 is a solid mower with a powerful Kawasaki engine. The aluminum deck is durable, and the mulching capability is excellent. The only downside is the price; it’s on the higher end for a 20-inch mower.
