John Deere S140 48-Inch 22 HP V-Twin Gas Lawn Tractor with Hydrostatic Transmission

Product Description The John Deere S140 Lawn Tractor combines strong V-twin engine performance, a wide cutting deck and easy-to-use hydrostatic controls for maintaining medium to large residential lawns. Its 22 HP, 724cc V-twin gasoline engine provides the power and torque required for regular mowing, mulching and grass collection while operating more smoothly than a single-cylinder engine. The engine features overhead valves, electronic ignition, cast-iron cylinder liners and a full-pressure lubrication system with a replaceable oil filter. These components help support reliable starting, efficient operation and longer engine life. A no-tools oil-drain system also simplifies routine oil servicing. Its 48-inch Edge™ cutting deck uses a three-blade cutting system to cover a broad area with each pass. The deep deck design helps lift grass before cutting, producing a clean and even finish. The smooth underside supports consistent clipping discharge and reduces areas where grass can collect. The deck is manufactured from heavy-duty 12-gauge steel and protected by dual-stage E-coat and powder-coated finishes. Rolled deck edges provide additional reinforcement, while four deck wheels help the mower follow rolling or uneven terrain without scalping the lawn. A TLT200 hydrostatic transmission provides continuously adjustable forward and reverse travel without manually shifting gears. Side-by-side foot pedals allow the operator to control direction and speed while keeping both hands on the steering wheel. The tractor can travel forward at speeds of up to approximately 5.5 mph and in reverse at up to 3.2 mph. The S140 includes a spring-assisted deck-lift lever with 13 cutting positions ranging from 1 to 4 inches. Height adjustments are available in precise 0.25-inch increments, making it easier to select the preferred cutting height for different grass types and seasonal conditions. Operator comfort is supported by a 15-inch cut-and-sewn open-back seat, wide footrests, anti-vibration floor mats and a large three-spoke steering wheel. The seat provides 5.5 inches of fore-and-aft adjustment across ten positions, helping accommodate operators of different heights. Bright LED headlights improve visibility in shaded or low-light areas. A mechanical fuel gauge can be viewed from the operator’s seat, while an hour meter helps track operating time and maintenance intervals.

Its twin-cylinder arrangement supports smoother operation, reduced vibration and improved sound quality compared with a single-cylinder engine. Cast-iron cylinder liners increase resistance to wear, while the full-pressure lubrication system circulates filtered oil through critical engine components. The system is particularly beneficial when mowing on inclines because it maintains more consistent lubrication than a basic splash-lubricated engine. 48-Inch Edge™ Cutting Deck The 48-inch Edge™ deck uses three cutting blades and a deep shell design to lift grass before cutting. This helps deliver a cleaner finish while improving the movement of clippings through the deck. The 12-gauge steel shell features reinforced rolled edges and corrosion-resistant coatings. Four deck wheels help maintain the selected cutting height over uneven areas and reduce the chance of lawn scalping. The standard three-in-one blades support: Side-discharge mowing Mulching with an optional mulch cover Grass collection with an optional rear bagger A mower wash port and hose connector are included to make cleaning the underside of the deck more convenient. Hydrostatic Pedal Transmission The TLT200 hydrostatic transmission eliminates the need to select fixed gears. Travel speed changes according to pressure applied to the forward or reverse pedal. This setup allows the operator to: Slow down when approaching obstacles Increase speed across open areas Change direction without manually shifting Keep both hands on the steering wheel Select precise travel speeds for different mowing conditions Adjustable Cutting Height A spring-assisted hand lever raises and lowers the cutting deck. The system offers 13 cutting positions from 1 to 4 inches in 0.25-inch increments. This broad adjustment range makes the S140 suitable for maintaining different grass varieties and adapting to seasonal growth, dry weather or taller mowing preferences. Operator Comfort The S140 includes a 15-inch high open-back seat with automotive-style cut-and-sewn construction. The seat can be adjusted while the operator remains seated and offers ten positions across 5.5 inches of travel. Additional comfort features include: Two seat-support springs Wide step-through operator platform Anti-vibration floor mats Large three-spoke steering wheel Cup holder Covered storage compartment Easy-to-read dashboard controls Durable Frame and Axle The tractor uses a robotically welded, full-length frame made from 12-gauge steel. High-strength frame rails support the engine, transmission and mower deck during regular residential use. A solid cast-iron front axle helps withstand repeated turning and movement over uneven ground. The molded hood cannot rust or dent and is designed to resist fading from ultraviolet light.
