The John Deere S120 steps up from the base S100 Series with a stronger V-twin engine and a few extra creature comforts, while keeping the same straightforward hydrostatic operation homeowners rely on.
It's one of the most frequently purchased tractors in the 100 Series lineup, striking a balance between price and everyday capability.
Why owners choose the S120
- 22 HP V-twin engine — more torque than the base S100 for tougher grass and larger yards.
- 42 in. Edge mower deck — a clean, even cut suited to most residential lots.
- Cruise control — hold a consistent speed on long, straight passes.
- MowerPlus app compatible — track fuel level, battery health, and mowing history from your phone.
- CargO Mount system — quick-attach points for a sun canopy, rear bagger, or other accessories.
