Operator station designed for operator comfort and convenience

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

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

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.

Operator comfort is enhanced with a 15 inch (38 cm) high-back, two-piece seat with an open back.

  • The open-back seat design keeps the operator cooler.
  • Especially helpful when operating the tractor for extended periods of time.
  • Easily adjusted forward or rearward while in the seat.
  • Seat travel of 5.5 inches (14 cm) and 10 different positions to adjust for operator height.
  • Two long seat springs give plenty of seat travel to smooth out the ride, keeping the operator comfortable while operating the tractor.
  • The seat can be tilted forward for protection from the elements and to provide easy access to the fuel tank.
  • A storage compartment and beverage holder are located on the right-hand fender for operator convenience and ease of use.

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

Instruments and controls are easy to find and convenient to use

The contoured dash has clean, attractive styling.

  • Controls are color-coded and labeled for easy identification.
  • Controls are logically placed and easy to reach.
  • The hour meter makes it easy to tell when oil changes and other maintenance should be performed.
  • Functional design of the controls provides good appearance and a comfortable feel.

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.

A spring-assisted, ergonomically designed lift-lever simplifies adjusting the mower cut height.

  • Increments of 1/4 inch (0.64 cm) allow fine-tuning the cut height.
  • Cut height is adjustable from 1 to 4 inches (2.5 to 10.2 cm).
  • The lift handle is shaped for easy use and is out of the way of entering or exiting operators.

The parking brake control is conveniently located for easy access. It holds the brake pedal securely in the locked position.

The heavy-duty electric PTO clutch is operated with a convenient dash-mounted switch. The available Reverse Implement Option (RIO) allows for movement in reverse without disengaging the PTO.

  • CAUTION: Children or bystanders may be injured by rotating blades. Before traveling forward or rearward, carefully check the area around the machine and disengage the mower before backing up. Backing up while the mower is engaged is strongly discouraged. RIO should be used only when operating another attachment or when the operator deems it necessary to reposition the machine with the mower engaged.
  • To use RIO, follow these steps:
    1. Stop forward travel.
    2. Look behind the machine to be sure there are no bystanders.
    3. Push and hold in the RIO switch while depressing the reverse pedal slightly. If the engine and mower or other attachment stops while repositioning the machine, return the attachment engagement lever/switch to the off position, then start the engine and engage the mower or other attachment. Begin again with step 2.
    4. Release the RIO switch and reposition the machine as the machine begins to move rearward.
    5. Resume forward travel. The mower or other attachment should continue operating.
    6. Repeat procedure to position the machine again.

The fuel tank gauge shows how much fuel is in the tank and can be seen without leaving the operator’s seat.

  • Easy to check fuel level.
  • Convenient location.

Serviceability is convenient with an easy-open hood

The one-piece hood opens easily to permit checking and servicing the engine.

  • Important service points are located within easy reach.
  • A service interval decal is provided inside the tractor hood for convenience when servicing the tractor.
  • The engine fuel and oil filters, the oil check/fill tube, and the oil drain tube are exposed for serviceability when the hood is opened.
  • The seat tilts up and out of the way to make adding fuel easy.
  • Molded-in color hood material reduces sound and will not rust or dent.
  • Same quality hood material as on larger John Deere tractors provides good resilience and UV resistance for an extended time.
  • Openings on the side let in plenty of cooling air while keeping the sound level low.
  • Two headlights provide good lighting for nighttime operation.

John Deere riding lawn mowers are supported by owner information web pages that include links to:

To speed access to owner information web pages, a QR code is printed onto a PIN label located near the fuel fill.

The QR code also includes the vehicle’s unique PIN, which enables warranty registration without the need to manually enter the vehicle’s PIN.
