John Deere S120 Lawn Tractor – 22 HP V-Twin, 42″ Edge Cutting Deck, Hydrostatic Transmission, 16″ Turn Radius

John Deere S120 Lawn Tractor – Smooth V-Twin Power, Homeowner Value

The John Deere S120 Lawn Tractor is the value-packed entry point to the S-Series lineup, pairing a 22 HP John Deere V-Twin gasoline engine with a 42-inch Edge Cutting System deck for smooth, reliable mowing on small to mid-sized home lawns. The V-Twin engine delivers refined power with less vibration than single-cylinder alternatives, making for a noticeably more comfortable ride.

The hydrostatic transmission with side-by-side foot pedals keeps operation simple and intuitive — no clutching, no shifting, just smooth speed control. A tight 16-inch turning radius provides excellent maneuverability around flowerbeds, trees, and landscape features. The automatic parking brake engages for convenience and safety, while easy-access service points simplify routine maintenance.

Designed for homeowners moving up from a basic rider, the S120 delivers the authentic John Deere lawn tractor experience — smooth power delivery, a clean consistent cut, and a comfortable ride — all at an accessible price point.
