John Deere S100 42 in. 17.5 HP GAS Hydrostatic Riding Lawn Tractor

17.5-hp (13.0-kW) engine

Engine oil filter and fuel filter

 

A 17.5-hp (13.0-kW), single-cylinder engine has plenty of power and torque to handle tough mowing, mulching, and bagging:

• Electronic ignition for fast starts
• Spring-return feature to ensure the operator will not mistakenly leave the throttle lever in the choke position
• 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
  • More effective when operating the tractor on an incline
• Large fuel filter for trouble-free operation

No-tools oil drain valve

 

The no-tools oil drain valve is easy to access when changing engine oil.

FUEL TANK

Convenient fuel filler opening

 

• The capacity is 2.4 U.S. gal. (9.1 L).
• The fuel filler opening is conveniently located under the seat.
  • Filling the tank without spilling is easy.
  • A tethered fuel tank cap is more convenient.
  • The sealed fuel cap helps keep vapors inside the tank.

  • Frame made of full-length welded steel for reliability

    Solid one-piece frame

    Solid one-piece frame

     

    The solid one-piece frame is constructed of 12-gauge, 0.105-in. (2.66-mm) steel:

    • Full-length, robotically welded frame design has high-strength steel rails for added strength and long life.
    • One-piece, steel fender deck is bolted to the frame.

    CAST-IRON FRONT AXLE WILL NOT BEND

    Front axle and wheel spindle

     

    The front axle is constructed of solid cast iron that will not bend:

    • Automotive-like steering system with sector and pinion steering gears and single drag link with a tie rod provides a very strong, low-effort, and tight-turning system.
    • Three grease fittings, on both steering spindles and center pivot, allow for regular lubrication to help maintain easy steering and minimize wear.
    • Large, 0.75-in. (1.9-cm) diameter wheel spindles provide excellent durability.

    FRONT BUMPER PROTECTS THE TRACTOR

    • Additional front-end protection
    • Attractive, bold style

    Snow removal is a strength of lawn tractors

    S140 Tractor with front blade, weights, and tire chains

    S160 Tractor with snow blower, weather enclosure, weights, and tire chains

     

    An advantage of lawn tractors is their ability to use equipment for snow removal. Lawn tractor owners can add a John Deere snow blower or front blade to make quick work of moving snow whenever the need arises. Weather enclosure and tire-chain attachments add comfort and performance.

    Equipment available for snow removal includes:

    • 44-in. (112-cm) Snow Blower
    • 46-in. (117-cm) Front Blade
    • Tire chains or TerraGrip traction belts
    • Weather enclosure
    • Weights

    Hydrostatic transmission gives an infinite choice of ground speeds

    Two-pedal speed/direction controls

    Forward speed control pedal in use

     

    A Kanzaki® Tuff Torq® hydrostatic transmission gives an infinite choice of speeds and makes changing the direction of travel easy. Side-by-side foot pedals control the speed and direction of travel:

    • Automotive-type accelerator controls ensure easy operation.
    • Operator can change direction without lifting foot off the platform.
    • Large pedal surface gives superior operator comfort.

    Hydrostatic transmission

     

    Appropriate transmissions are used in each model, depending on rear tire size and tractor performance requirements, to ensure excellent performance and reliability:

    • Tuff Torq TLT200 – S100, S110, S120, S130, S140, and S160
    • Tuff Torq K46 – S170 and S180

    Comfortable operator station, left side

     

    The operator station is designed for operator comfort and easy operation:

    • Controls are positioned where they are easy to reach and easy to use to control the tractor.
    • Steering wheel is positioned and angled to give the operator plenty of room and steering comfort.
    • Seat is positioned to provide the most comfortable operator position.

    Steering wheel and dash

    Wide footrest with debris channels

     

    Controls are easy to see and use:

    • Large, three-spoke steering wheel for greater operator comfort and control
    • Ignition switch is on the dash for starting ease

    Wide footrest areas with non-slip, anti-vibration floor mats are provided for operator comfort:

    • The wide footrest makes it easier to step over the mower deck while entering or exiting the seat.
    • Debris-removing channels help keep the footrest area clean and dry.

    Comfortable seat

    Easily adjusted seat and beverage holder

     

    The operator seat has an 11-in. (28-cm) back height. It can be easily adjusted forward or rearward while the operator is in the seat, with seat travel of 5.5 in. (14 cm) and 10 different positions.

    A beverage holder is located on the right-side fender for operator convenience.

    Seat springs give a smoother ride

    Seat tilted forward

     

    Two long seat springs give plenty of seat travel to smooth out the ride, keeping the operator comfortable while operating the tractor.

    Seat can be tilted forward for protection from the elements and to provide easy access to the fuel tank.

    Storage compartment and beverage holder

     

    A storage compartment and beverage holder on the right-side fender are conveniently located and easy to use.

    NOTE: A storage compartment cover is standard on S120, S130, S160, S170, and S180 Tractors and optional on the S100, S110, and S140.
