The 100 Series Ride-on Mowers combine strength and reliability with yard-friendly simplicity, comfort and control. With a choice of models and a wide range of features and options to choose from, the 100 Series has something for everyone. These robust ride-on mowers are engineered for years of trouble-free service and combine superb cut quality with outstanding ease of use.

The John Deere S100 lawn tractor is the most affordable 42-inch deck model of the 100 Series line up. The ride is comfortable. The S100 features a hydrostatic transmission, side-by-side foot pedals, enhanced styling, adjustable controls and 11-in back seat. And the 42-inch Edge™ Cutting System is time-tested and proven to offer superior cut quality and can be easily equipped to bag or mulch. The 17.5-HP, single cylinder, John Deere engine has plenty of power to handle tough mulching, mowing and bagging conditions (coverage up to one acre).

Powerful engine features full-pressure lubrication for long life

  • A 13-kW (18-hp), single-cylinder engine has plenty of power and torque to handle tough mowing, mulching, and bagging.
  • Electronic ignition for fast starts
  • Cast-iron cylinder liner for long engine life
  • Overhead valves for excellent power and fuel economy
  • Anti-vibration system
  • Full-pressure lubrication and oil filter for cleaner oil, prolonging engine life, and extending the time between oil changes

Frame made of full-length welded steel for reliability

  • The solid one-piece frame is constructed of 12-gauge, 2.66-mm (0.105-in.) steel.
  • Cast-iron front axle will not bend
  • Front bumper protects the tractor
  • The front bumper is included on the S130 and S140. It is available as an optional attachment for the S100, S110, and S120.
  • The CargO Mount system is a combination of front- and rear-mounting points providing convenient and easy installation of the sun canopy, rear bagger, and other attachments.

Hydrostatic transmission gives an infinite choice of ground speeds

  • Automotive-type accelerator controls ensure easy operation.
  • Operator can change direction without lifting foot off the platform.
  • Large pedal surface gives superior operator comfort.
  • Appropriate transmissions are used in each model, depending on rear tire size and tractor performance requirements, to ensure excellent performance and reliability:

The Edge™ cutting system gives superior performance

  • The Edge cutting system has been trademarked to emphasise the advantages of the John Deere mower deck designs. They give superior mowing performance, convenience, and reliability.
  • The 107-cm (42-in.) Edge Mower Deck is a two-spindle design with heavy-duty characteristics:
  • The 13-gauge, 2.3-mm (0.09-in.) steel deck provides years of dependable mowing.
