Operation

WARNING

Loading a unit on a trailer or truck increases the possibility of backward tip-over. Backward tip-over could cause serious injury or death.

Use extreme caution when operating a unit on a ramp.

Use only a single, full width ramp; Do Not use individual ramps for each side of the unit.

If individual ramps must be used, use enough ramps to create an unbroken ramp surface wider than the unit.

Do Not exceed a 15° angle between ramp and ground or between ramp and trailer or truck.

Avoid sudden acceleration while driving unit up a ramp to avoid tipping backward.

Avoid sudden deceleration while backing unit down a ramp to avoid tipping backward.

WARNING

Loading the mower onto a trailer without strong enough or properly supported ramps could be dangerous. The ramps could collapse causing the unit to fall, which could cause injury.

Use proper ramps that are secured to the truck or trailer.

Keep feet and legs out from under the unit when loading and unloading.

If necessary, use assistance when loading.

Consult the NFPA 58: Liquefied Petroleum Gas Code for additional information regarding LPG transportation.

Be sure the fuel valve is closed on the tank(s).

Place spare LPG tank(s) in a DOT approved storage cage.

Transport tanks in an upright, vertical and secure position to minimize movement,

tipping, or physical damage relative to other tanks or to the storage cage while in transit.

Place tanks so that valves, fittings, or gauges are protected from physical damage during transport.

Place tank(s) in a well-ventilated trailer.

Do Not store the tank(s) or machine with tank(s) in an area where the temperature can rise above 120°F (49°C). If the temperature exceeds approximately 160°F (71°C), the tank will release highly flammable propane vapor. See Preparation in the Safety Section.

Do Not transport LPG tank(s) in the passenger space of a vehicle.

Do Not transport leaking fuel tanks.

Trailers must have appropriate markings to transport LPG.

Follow NFPA 58 and state and local regulations for transporting LPG.

Loading a Unit

Use extreme caution when loading units on trailers or trucks. One full width ramp that is wide enough to extend beyond the rear tires is recommended instead of individual ramps for each side of the unit. The lower rear section of the tractor frame extends back between the rear wheels and serves as a stop for tipping backward. Having a full width ramp provides a surface for the frame members to contact if the unit starts to tip backward. If it is not possible to use one full width ramp, use enough individual ramps to simulate a full width continuous ramp.

Ramp should be long enough so that the angles between the ramp and the ground and the ramp and the trailer or truck do not exceed 15°. A steeper angle may cause mower deck components to get caught as the unit moves from ramp to trailer or truck. Steeper angles may also cause the unit to tip backward. If loading on or near a slope, position the trailer or truck so it is on the down side of the slope and the ramp extends up the slope. This will minimize the ramp angle. The trailer or truck should be as level as possible.

Important: Do Not attempt to turn the unit while on the ramp, you may lose control and drive off the side.
