The Gravely ZT brings commercial features and construction to a residential compact design. This is a comfortable, durable zero-turn mower that gives you the maneuverability you need to finish the job quickly – without sacrificing a beautifully cut lawn. User-Friendly Design Faster than mowing with a walk-behind and easier to operate than a tractor, this compact mower is built on a robust frame and is perfect for small and medium yards. Powerful Engines Equipped with a Kawasaki FR600V 18HP or FR651V 21.5HP engine, depending on the model's deck size. 16" High Back Seat A comfortable seat feels as good as it looks with natural airflow to enhance operator comfort.
