The best zero turn mower for professional landscapers on a budget. If money were no object, you'd equip your lawn care business with an advanced, commercial-grade zero turn mower. If you're on a budget, you'll be glad to know you still can. The compact sized IS® 600Z will fit most garden sheds and trailers with room to spare, yet comes loaded with all the power and enhancements that make Ferris mowers an industry giant. That means you can perform any lawn project like an expert while saving time and money. 

How do we do it? Start with our signature full rear adjustable suspension system complemented by a shock-assisted, pivoting front axle. You'll feel the difference immediately, a surprisingly refined ride for a wide area mower, providing greater control to mow evenly over rough ground faster – with less scalping than a non-suspension mower. Traction is also improved for added stability riding up hills and around obstacles.

On to our rock-steady deck options. Under the 48" models, you'll find our signature iCD™ Cutting System, equipped with an included professional lawn striper for an expertly groomed finish every time. Our 44" models feature a 10-gauge fabricated cutting deck and can be outfitted with the lawn striper (sold separately for the 44" deck). Both decks have greaseable aluminum spindles for dependable service and long-lasting Marbain® steel blades for a consistently superior cut. Large-acreage homeowners, prepare to make your neighbors jealous.

This spirited mid mount mower comes with your choice of powerful V-twins. Consider the American-made, 25-gross-horsepower Briggs & Stratton Commercial Turf Series™ motor. Or, choose the 18.5-gross- hp Kawasaki® FS600V. You can pair either power plant with a 44- or 48-inch cutting deck. Just like its big brother, the IS 700Z, this riding mower comes equipped with our dual commercial Hydro-Gear® ZT-3400® transaxles – one more feature raising the bar not only in quality, but also commercial readiness. When the badge reads Ferris on the outside, you can rest assured there's proven performance inside. Perhaps you thought owning a commercial-grade zero turn mower was a pipe dream. Now you know nothing stands in your way. We built the nimble IS 600Z to close the gap between what you can afford and what you truly want.
