configuration is used primarily for towing. A
machine configured to free-wheel without operator
knowledge could result in death or serious injury
and property damage.

that is firm and level.

machine must be towed, do not
exceed 2 mph / 3.2 km/h.

between the non-steer wheels.

under the drive chassis for support.
4 Disengage the drive hubs by turning over the
