Robust enough to tackle even the toughest applications with power to spare, the Grasshopper Model 735BT riding lawn mower combines zero-turn maneuverability with rugged performance with unparalleled operator comfort to eliminate fatigue and maximize productivity. The mower is designed with professional-grade quality for years of dependable service for both homeowners and landscapers alike. Out-front reachability reduces secondary trimming. Decks may be rotated to a vertical position with PowerFold® deck lift/electric height adjustment for easy cleaning and to fit more mowers on a trailer. Decks remove in favor of other implements for year-round productivity.
