With an advanced suspension system and a commercial-grade 52” mowing deck, the STIHL RZ 552 K zero-turn mower is built for durability, operator comfort, and a long life span. The two-belt deck pulley system reduces stress on each belt to keep the 24 hp Kawasaki engine running cooler with less maintenance. The Hydro-Gear® ZT-3400 transaxles enable 10 mph forward ground speed and 5 mph in reverse, allowing for smooth and efficient cutting.
