Field-installed propane conversion kits for Commercial Walk-Behind Mowers, QuikTrak™ Mowers, and Commercial ZTrak™ Mowers
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.
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 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.

- Wide-bend, large-diameter steering levers swing out easily for entry and exit from the operator platform.
Brake & Go starting system
The Brake & Go starting system is a John Deere exclusive. This feature makes the starting process on all ZTrak™ mowers easier, while also making it possible to remove two interlock switches from the machine.
The Brake & Go starting procedure helps a novice operator look and feel like a professional. To start the machine, the parking brake must be engaged. It does not matter whether the power take-off (PTO) switch is on or off, nor does it matter if the control levers are pulled in or in the out position.
As long as the parking brake is engaged, the machine will start. When the parking brake is applied, the control levers cannot be moved to the forward or reverse positions.
The motion control levers have two height positions and can also be adjusted forward or rearward within the slotted holes. The levers should be adjusted so the operator can achieve a full range of control operation comfortably.
The easy-to-turn (from-the-seat) tracking adjustment allows operators to keep their mowers straight and able to produce professional striping results.
Onboard storage and cup holder
Several storage areas are provided on the ZTrak machines. A convenient cup holder is also available.
Right-hand control panel
The controls are grouped together on the right console, providing one central location for key switch, throttle, PTO engagement, height-of-cut, diagnostics, and hourmeter.
- Rocker-type PTO switch
- Height-of-cut knob with transport lock
- Key switch
- Separate choke control
- Easy choke operation yields less fouling of plugs
- No choke required for the EFI models
Easy-to-operate height-of-cut adjustment enables on-the-go changes
An easy-to-use cutting-height lift system allows the operator to adjust the mower deck height with no tools and minimal effort. The easy-to-grip knob allows operators to dial in the desired height of cut (HOC).
Cutting height can be adjusted from approximately 1 in. to 5.5 in. (2.5 cm to 14 cm). Each increment on the knob adjusts the HOC approximately 0.25 in. (0.64 cm). The deck can also be raised and locked in a transport position to provide maximum ground clearance when moving the machine from one area to another.
The transport lock function allows the deck to be returned to the previous HOC after being in the transport position:
- Use the foot-lift pedal to lift the deck and engage the transport lock.
- Rotate the knob to adjust from 1 in. to 5.5 in. (2.5 cm to 14 cm) in 0.25-in. (0.64 cm) increments.
This design increases productivity by allowing operators to change the cutting height without having to leave the seat.
Standard comfort and convenience allows for easy deck height adjustment and power take-off (PTO) shutoff
The comfort and convenience package combines large, ergonomically angled control levers with specially padded grips to provide unmatched comfort and reduced fatigue:
- Keeps hands on the control sticks to minimize equipment damage and make them more comfortable over long operating days.
The control levers have built-in electronic controls to raise or lower the mower deck or disengage the mower blades.
The push button (A) on the left motion control lever raises the mower deck.
The push button (B) on the right-hand control lever shuts off the PTO.
Once the PTO has been shut off using the button, the PTO switch must be pushed down and pulled up again to engage the PTO.
Mower is easy to service with many accessible components
The design of the Z900 Series makes many service components reachable and easily accessible from the ground.
- Large, open engine compartment at the rear of the machine provides convenient servicing and ensures the engine heat is directed away from the operator.
Onboard maintenance chart
All ZTrak™ Mowers come with an onboard maintenance chart that is conveniently located inside the right-hand console. The service interval chart gives necessary service intervals.
The hourmeter shows the number of hours the machine is run when the key switch is in the on position. It only counts the hours the engine is actually running. Machine diagnostics are the first step of a monitoring system to help operators quickly diagnose common downtime issues. A trouble code light is included on the hourmeter.
Use of the hourmeter and service interval chart helps determine when the machine will need service.
Rollover protective structure (ROPS) enhances operator safety
The ZTrak™ Z900E, M, and R Series Mowers are equipped with a standard two-post folding ROPS and seat belt. The folding ROPS enhances operator safety and provides ample clearance when storing the mower in garages or sheds:
- ISO21299 certification
The ROPS system can be repositioned without the use of tools. Under normal operation, the ROPS should be in the up position. If operating in low clearance areas, they can be folded and secured out of the way. The ROPS can also be pinned halfway down to accommodate machines equipped with a material collection system.
