Propane conversion kit on a Walk-Behind Mower

Propane conversion kit on a ZTrak Mower

John Deere provides application-specific Environmental Protection Agency (EPA) approved field-installed propane conversion kits for specific John Deere Commercial Walk-Behind Mowers, QuikTrak Mowers, and ZTrak Mowers. The conversion kits include all components required to convert the engines to operate on propane fuel. Single-tank or dual-tank brackets (depending on the vehicle) are provided for securely holding the propane tank(s) to the vehicle.

Propane tanks are not included.

An optional altitude kit is required when operating at altitudes above 2000 ft (610 m). The operator’s manual with the propane conversion kit provides further details. Parts must be ordered separately through John Deere Parts.

Propane facts:

• Propane is flammable and commonly used as a fuel.
• The molecular formula of propane is C3H8, and it is in the family of liquefied petroleum gases (LP gases). The other LP gases include butane, propylene, butadiene, butylene, isobutylene, and mixtures thereof.
• Propane is commonly available and has proven to be a dependable, safe, economical, and clean-burning fuel. It can be used as household fuel, industrial fuel, and fuel for internal combustion engines. Propane has been used as a fuel since 1910.
• At atmospheric pressure, propane boils at -44°F (-42.2°C), meaning it typically exists as a vapor. However, when contained under pressure, such as in a propane cylinder, it can exist as a liquid.
• Propane is naturally odorless, but includes an additive odorant, usually mercaptan, which gives it a distinct odor.
• Vapor propane is heavier than air, meaning it will settle in low areas such as along the ground or in drains.

 Advantages of John Deere propane conversion kits include:

• Reduced fuel costs, up to 30 percent depending on fuel prices
• Lower emissions
• Reduced fuel-system maintenance
• Maintains John Deere warranty
• EPA and CARB certified
• May qualify for national and state rebate and incentive programs. Please visit www.propane.com/commercial-landscape/programs-and-incentives/ for further information.

  • The dual-tank brackets are designed for two 20-lb (9.1-kg) Worthington tanks.
    • Tanks are not included.
• ZTrak Mowers have single-tank and dual-tank mounting options.
• The single-tank, left-side bracket is designed for one 33-lb (15-kg) or 43-lb (19.5-kg) Worthington tank.
  • Tank is not included.
• The dual-tank brackets are designed for two 33-lb (15-kg) Worthington tanks.
• Tanks are not included.

Tweel rear tire on QuikTrak Mower

NOTE: 18x8.5N10 Tweel turf tires are available as an ordering option for QuikTrak 648R, 652R, 652R EFI, 661R, and 661R EFI Mowers. Tweels for QuikTrak Mowers are not available as base code equipment.

John Deere leads the commercial zero-turn mower industry with use of the Michelin X Tweel Turf technology for the QuikTrak Mowers.

Michelin is a world leader in tire manufacturing and technology. This airless radial tire solution is an industry first for John Deere, which provides an additional advantage to John Deere operators.

Advantages of the Michelin X Tweel Turf include:

• Mowing performance is improved.
  • Unique energy transfer within the poly-resin spokes reduces the bounce associated with pneumatic tires.
  • Excellent curb climbing due to the Michelin X Tweel Turf construction and flexibility.
  • More consistent cut quality because inconsistent tire pressure is eliminated.
• Uptime is improved.
  • The exclusive technology eliminates downtime and associated cost due to flat or damaged tires.
  • Punctures and sidewall damage no longer result in downtime.
• Cost of operation is reduced.
  • Cost of repairs and maintenance is reduced. One single unit replaces the current tire, wheel, and valve assembly. There is no need for complex tire-mounting equipment.
  • No need to spend time checking and optimizing tire pressure.
  • The need to purchase and stock plug kits and spare tires is eliminated, particularly for professional landscape contractors and government agencies who normally stock them.
  • The tire tread will last up to three times longer than current pneumatic tires because automotive-grade rubber is used for the tread.

Heavy-duty construction provides the ultimate in performance and reliable operation:

• High-strength, poly-resin spokes carry the load.
• Four-hole, heavy-duty steel hub easily bolts onto any R Series QuikTrak Mower.
• Zero degree, high-tensile, proprietary carcass provides great lateral stiffness while resisting damage from impact and penetration.
