John Deere S100 42-Inch 17.5 HP Hydrostatic Lawn Tractor

Product Description The John Deere S100 Lawn Tractor is a dependable residential riding mower built for straightforward operation, comfortable handling, and efficient routine lawn care. Its combination of a 17.5 HP engine, 42-inch Edge™ cutting deck, two-pedal hydrostatic transmission, LED headlights, and broad attachment compatibility makes it a practical choice for small to medium residential properties. Power is supplied by a 17.5 HP, 500cc single-cylinder overhead-valve engine. The air-cooled engine uses full-pressure lubrication with a replaceable oil filter, helping circulate clean oil throughout the engine during normal operation and when mowing on moderate inclines. A cast-iron cylinder liner, electronic ignition, anti-vibration system, and cartridge-style air cleaner contribute to reliable performance and easier maintenance. A conveniently positioned no-tools oil-drain valve simplifies routine oil changes. The engine also includes a spring-return choke control that helps prevent the throttle from being unintentionally left in the choke position after startup. The S100 features a 42-inch Edge™ mower deck manufactured from durable 13-gauge stamped steel. Its deep-deck design lifts grass for a clean and uniform cut, while the smooth underside helps reduce clipping buildup and supports even discharge. Rolled outer deck edges add structural strength, and dual-stage E-coat and powder-coat finishes help protect the deck against corrosion. Two factory-installed three-in-one blades support: Standard side-discharge mowing Mulching with an optional mulch cover or mulching attachment Grass collection with a compatible rear bagger The optional mulch cover can be installed without tools and works with the standard blades. A high-performance mulching attachment with specialized blades is also available separately for improved clipping reduction. Cutting height can be adjusted through 13 positions from 1 to 4 inches, in precise quarter-inch increments. A spring-assisted hand-grip lever reduces the effort needed to raise and lower the deck, while two adjustable mower wheels help prevent scalping on mildly uneven terrain. The deck also includes an Easy-Level adjustment system and a wash port for convenient underside cleaning. The TLT200 hydrostatic transaxle provides continuously variable forward and reverse travel without manual gear changes. Side-by-side foot pedals allow the operator to control speed and direction while keeping both hands on the steering wheel. The tractor reaches speeds of up to approximately 5.5 MPH forward and 3.2 MPH in reverse. An 18-inch turning radius helps the S100 maneuver around trees, landscaping, pathways, and garden features. Its traditional sector-and-pinion steering system gives homeowners familiar, predictable control. The open operator platform provides comfortable access to the seat and controls. A wide anti-vibration footrest with debris channels helps reduce discomfort during longer mowing sessions, while the one-piece seat includes fore-and-aft adjustment and spring suspension. Additional conveniences include: Two LED headlights Digital hour meter Mechanical fuel gauge viewable from the seat Cup holder Storage compartment Wide operator platform Easily accessible controls QR code providing model-specific maintenance and support information The rear-mounted 2.4-gallon fuel tank includes a centrally positioned fill opening, and the mechanical fuel gauge allows the operator to check fuel level without leaving the seat. Beyond mowing, the S100 can accept compatible John Deere attachments for bagging, hauling, spreading, lawn cleanup, and seasonal property maintenance. Available accessories may include grass baggers, utility carts, mulch equipment, lawn sweepers, spreaders, snow-removal equipment, weather enclosures, and other approved implements. Attachments are sold separately and availability may vary by region. The John Deere S100 is assembled in Tennessee and is covered by a two-year or 120-hour bumper-to-bumper limited warranty, whichever occurs first.
