John Deere S140 Lawn Tractor

Powerful engine features full-pressure lubrication for long life

A 22-hp (16.4-kW) V-twin engine has plenty of power and torque to handle tough mowing, mulching, and bagging:

Fuel tank

• 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

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.

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
 

The front bumper is included on the S130, S140, S160, S170, and S180. It is available as an optional attachment for the S100, S110, and S120.

• Additional front-end protection
• Attractive, bold style

CargO Mount™ system makes installation of rear bagger and other attachments easy

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.

Snow removal is a strength of lawn tractors

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

• 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:

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

Mower deck height adjustment

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

• Increments of 1/4  in. (0.64 cm) allow fine-tuning the cut height.
• Cut height is adjustable from 1 to 4 in. (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.

Parking brake control

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

Using RIO

CAUTION: Children or bystanders may be injured by rotating blades. Before traveling forward or rearward:

• Carefully check the area around the machine.
• Disengage the mower before backing up.

NOTE: 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.

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 for a hydrostatic transmission or moving the transmission shift lever to the rear slot (reverse) for a continuously variable transmission (CVT)/automatic transmission.

NOTE: If the engine and mower or other attachment stops while repositioning the machine, return the attachment engagement lever/switch to the off position. Start the engine and engage 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.
