Engine is powerful and smooth-running V-twin design

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

  • V-twin cylinder design for greater torque, lower vibration, and improved sound quality
  • 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 liners for longer engine life
  • Overhead valves for excellent power and fuel economy
  • 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
  • No-tools oil drain system for servicing convenience
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.
CAST-IRON FRONT AXLE WILL NOT BEND

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.

  • Additional front-end protection
  • Attractive, bold style

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
Hydrostatic transmission gives an infinite choice of ground speeds

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.
