John Deere S120 Lawn Tractor

S-Series. 22 HP V-Twin. 42-Inch Edge Deck.

The John Deere S120 Lawn Tractor pairs a 22 HP John Deere V-twin gasoline engine with a 42-inch Edge Cutting System mower deck. It’s positioned between the S110 and S130 in the line, offering the same 22 HP V-twin as the S130 in a slightly simpler trim level.

Hydrostatic transmission with side-by-side foot pedals, a 16-inch turning radius, and a comfortable operator seat make this a practical home-lawn mower for half-acre to two-acre properties.

Like all S-Series lawn tractors, the S120 accepts mulching kits, bagger systems, tow-behind attachments, and the broader John Deere home-owner accessory ecosystem.
