Propane conversion kit on a Walk-Behind Mower Propane conversion kit on a ZTrak Mower
John Deere provides application-specific Environmental Protection Agency (EPA) and California Air Resources Board (CARB) 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.
Optional altitude kit is required when operating at altitudes above 2000 ft (610 m). The operator’s manual provided with the propane conversion kit provides further details. Parts must be ordered separately through John Deere Parts.
- 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.
