John Deere S120 Lawn Tractor – 42″ Edge Deck, 22 HP V-Twin Engine, Hydrostatic Riding Mower for 0.5–2 Acre Lawns

The John Deere S120 Lawn Tractor offers the power of a 22 HP V-twin engine in a practical, mid-line S-Series package. Positioned between the S110 and S130, it delivers the same 22 HP engine found in the S130 with a slightly simplified trim — giving you the muscle you need without paying for features you don’t require.

22 HP V-Twin Power: The John Deere V-twin engine provides 22 horsepower with the smoothness, low vibration, and torque that only a twin-cylinder design can deliver. Whether cutting thick grass, climbing gentle slopes, or pulling a cart, the S120 handles it with confidence.

42-Inch Edge Cutting System: The 42-inch fabricated mower deck uses John Deere’s Edge Cutting System for a clean, manicured finish. The deep-deck design optimizes airflow to lift grass for a uniform cut and improves discharge to reduce clumping in damp conditions.

Hydrostatic Drive: Side-by-side foot pedals give you intuitive control — press the forward pedal to go, the reverse pedal to back up. No clutching, no shifting. You can vary ground speed infinitely to match grass density, terrain, and trimming needs.

Agile Maneuvering: With a 16-inch turning radius, the S120 navigates easily around flower beds, trees, mailboxes, and landscape edges. Less trimming means faster mowing.

Accessory Ready: Like all S-Series tractors, the S120 accepts the full John Deere home-owner accessory lineup including:

• Mulching kits for nutrient recycling
• Bagger/collection systems for clean pickup
• Tow-behind carts, aerators, dethatchers, and spreaders
• Lawn sweepers and sprayers

Operator Comfort: High-back adjustable seat, ergonomic control placement, and smooth hydrostatic drive make long mowing sessions more comfortable. The ride is stable and controlled across undulating terrain.
