Maintenance; Periodic Maintenance - Exmark Ultra Vac Operator's & Parts Manual

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.
DO NOT attempt to turn the unit while on the ramp, you may lose control and drive off
the side.
Avoid sudden acceleration when driving up a ramp and sudden deceleration when
backing down a ramp. Both maneuvers can cause the unit to tip backward.
