Product Description

The John Deere S140 48-Inch 22 HP V-Twin Gas Hydrostatic Riding Lawn Tractor delivers a practical combination of strong residential power, wide-deck productivity, smooth hydrostatic operation, and the familiar durability of John Deere’s 100 Series.

Built for homeowners who want to cover more lawn in fewer passes, the S140 is equipped with a 48-inch Edge™ mower deck. The larger deck gives the tractor an advantage over smaller 42-inch lawn tractors when mowing medium and larger residential properties, helping reduce the number of passes required during routine lawn maintenance.

Power comes from a 22 HP V-Twin gasoline engine. John Deere identifies the engine as model 44N677 (M44) with a displacement of 44.2 cubic inches. The V-Twin layout is well suited to the wider 48-inch cutting system, providing smooth, consistent power for normal mowing conditions.

The engine uses an overhead-valve design with full-pressure lubrication and a replaceable oil filter, supporting dependable residential operation and straightforward routine maintenance.

Driving the S140 is easy thanks to its hydrostatic transmission with side-by-side foot pedals. Rather than selecting fixed transmission gears, the operator can smoothly control forward and reverse movement using separate pedals.

This setup is particularly useful when mowing around landscaping, trees, fences, garden borders, and other obstacles because travel speed and direction can be adjusted frequently without manual shifting.

Blade engagement is handled by an electric PTO system, allowing the mower deck to be conveniently engaged from the operator station.

The 48-inch mower deck uses a three-blade rotary cutting system. Cutting height can be adjusted from approximately 1 inch to 4 inches, allowing the mowing height to be tailored to different grass conditions, seasons, and lawn-care preferences.

The S140 also places significant emphasis on operator convenience. A comfortable 15-inch seat, open operator platform, accessible controls, LED headlights, hour meter, and mechanical fuel gauge help make regular mowing more comfortable and straightforward.

A 2.4-gallon rear-mounted gasoline tank provides useful operating capacity, while the fuel gauge is positioned so the operator can check the fuel level while seated.

The tractor is also designed as more than a basic mower. Compatible John Deere accessories can expand its capabilities for grass collection, hauling, seasonal cleanup, and other property-care jobs.

For homeowners seeking a traditional lawn tractor with a wider cutting deck, V-Twin power, smooth pedal-controlled hydrostatic drive, and excellent attachment versatility, the John Deere S140 is a highly capable residential mowing platform.
