Proof that value and performance are not mutually exclusive. The Pioneer S-Series gives lawn care professionals even more to like. The 48- and 52-inch models receive the patented UltraCut? Series 3 deck system. And the 60-inch gets the UltraCut Series 4, the same deck used on our Lazer Z? S-Series mower, featuring heavy-duty cutter housings and a deeper deck for increased productivity. The S-Series also gives you the choice of a ZT3100 (on 48??52?). The 60? models ZT3400 integrated transmission provide a seriously smooth ride. Can also reach speeds up to 9 mph, which results in maximum productivity. Comes equipped with the full-suspension seat which enhances operator comfort. Not available in CA.
