Product Description

The John Deere S140 48-Inch 22 HP V-Twin Hydrostatic Riding Lawn Tractor combines dependable engine power, a wide cutting system, simple hydrostatic operation, and operator-focused comfort in a versatile residential lawn tractor.

Designed as part of John Deere’s 100 Series, the S140 is particularly attractive to homeowners who want the productivity of a 48-inch cutting deck without moving into a significantly larger or more complex mower platform.

Power comes from a 22 HP V-Twin gasoline engine. John Deere identifies the engine as model 44N677 (M44) with 44.2 cubic inches of displacement. Its overhead-valve design, full-pressure lubrication system, replaceable oil filter, and air cooling are designed to support dependable residential mowing performance.

The V-Twin arrangement provides smoother power delivery than many basic single-cylinder riding mower engines and gives the S140 useful power for mowing, normal mulching applications, and compatible lawn-care attachments.

At the center of the mower is a 48-inch John Deere mower deck. The wide cutting path lets the tractor cover substantially more ground per pass than smaller 42-inch lawn tractors, making the S140 a strong choice for homeowners who regularly maintain medium-to-large residential lawns. John Deere’s current product listing identifies the S140 with a 48-inch Edge™ mower deck.

The deck uses three rotary cutting blades, providing cutting coverage across the full 48-inch width. Cutting height can be adjusted from approximately 1 inch to 4 inches, allowing the operator to adapt mowing height to grass type, season, weather, and lawn conditions.

Driving the S140 is straightforward thanks to its hydrostatic transmission with side-by-side foot pedals. Instead of manually changing gears, the operator controls forward and reverse movement through dedicated pedals. This makes speed changes intuitive when maneuvering around trees, landscaping, flowerbeds, or other obstacles.

The S140 also features an electric PTO, allowing the mower deck blades to be engaged using an electrical control rather than a manual mechanical engagement system.

A rear-mounted 2.4-gallon gasoline tank provides fuel capacity suitable for extended residential mowing sessions. A mechanical fuel gauge can be viewed from the operator position, helping the user monitor remaining fuel without stopping to inspect the tank manually.

Operator convenience is enhanced by LED headlights, an hour meter, comfortable seating, accessible controls, and John Deere’s familiar open operator platform.

Beyond mowing, the S140 can serve as a multipurpose property-maintenance tractor. John Deere offers compatible attachments for lawn tractors including bagging systems, carts, snow-removal equipment, and other property-care accessories. These attachments are optional and are not included with the standard tractor.

For homeowners wanting a traditional riding lawn tractor with a wider deck, V-Twin power, intuitive pedal-controlled hydrostatic transmission, and the ability to use compatible lawn-care attachments, the John Deere S140 provides a strong combination of productivity and everyday usability.

Transmission & Drive Configuration

The John Deere S140 uses a hydrostatic 2-wheel-drive transmission controlled by side-by-side foot pedals.

This system allows the operator to control travel speed and direction without selecting conventional transmission gears.

The pedal configuration is especially useful when:

• Maneuvering around trees
• Backing away from obstacles
• Transitioning between open and confined lawn areas
• Performing routine property-maintenance work
