John Deere S100 42-Inch 17.5 HP Gas Hydrostatic Riding Lawn Tractor

Product Overview

The John Deere 42-Inch Lawn Tractor is designed to provide dependable mowing performance, easy operation, and year-round versatility for residential properties. Powered by a 17.5 HP John Deere single-cylinder engine and equipped with a 42-inch Edge™ mower deck, this lawn tractor provides efficient cutting performance for flat and moderately landscaped terrain.

The 42-inch Edge™ cutting deck provides a wide mowing path while delivering a clean and consistent cut. It can be configured for side discharge, mulching, or bagging with compatible accessories, giving homeowners flexibility when managing grass clippings.

A TLT200 hydrostatic transmission with side-by-side foot pedals provides smooth control of speed and direction without requiring manual gear shifting. The intuitive pedal arrangement operates much like a car, making it easier to maneuver around trees, flower beds, landscaping, and other obstacles.

The tractor is also designed with operator comfort in mind. An adjustable high-back seat, wide footrest, anti-vibration floor mats, ergonomic controls, cup holder, storage tray, and headlights help provide a comfortable and convenient mowing experience.

For additional durability, the tractor features a full-length welded steel frame and cast-iron front axle. The integrated CargO Mount™ system allows compatible attachments to be installed for additional lawn and seasonal property-maintenance tasks.
