When productivity, durability, and operator comfort all matter, the Toro Z Master® 4000 Series HDX with MyRIDE® Suspension (Model 74059) delivers in a big way. This commercial-grade zero-turn mower is built to dominate long days, rough terrain, and demanding schedules—while keeping the operator fresh and productive.
Powered by a 31 HP Kawasaki FX921V 999cc engine, the 4000 HDX pairs massive power with Toro’s legendary 60" TURBO FORCE® cutting deck, built from 7-gauge high-strength steel and supported by a fully tubular chassis with reinforced bumper. You can run full throttle with confidence, knowing the deck is engineered to maintain cut quality at speeds up to 12 MPH.
The standout feature is Toro’s MyRIDE® Suspension System, offering up to 3 inches of platform travel to absorb bumps, ruts, and uneven terrain. Combined with 26" Voodoo Trac™ drive tires, this mower provides superior traction, hillside control, and a higher vantage point for improved visibility.
With LED headlights, USB ports, phone and cup holders, electronic deck lift assist, and Horizon360® Business Management Software compatibility, this mower is designed to keep you efficient, comfortable, and profitable—even during the longest days.
