Schulte FX-1800 Operator's Manual page 97

Never raise the mower entirely while the blades are
turning. If the mower must be raised higher than 12"
from ground level, disengage the tractor PTO and
wait for all mower rotation to come to a complete
stop before proceeding to raise the mower. NEVER
raise the mower wings while the blades are turning.
When turning, the angle between the tractor and
mower should not be so great that a clattering of
the U-joints occurs. Sharp turns can cause
premature failure of the joints and place pressure
on the tractor PTO shaft and could cause extensive
mechanical damage to the mower and tractor.
If the mower is operated in conditions that require
frequent sharp turning, the mower should be
equipped with a Constant Velocity driveline. CV
joints enable the tractor PTO shaft and mower
driveline to be angled safely up to 80 degrees with
no damage to the mower or driveline.
Do not let the Blades turn when the Mower Deck is raised for any
reason, including clearance or for turning. Raising the Mower deck
exposes the Cutting Blades which creates a potentially serious hazard
and could cause serious injury or even death from objects thrown from
the Blades.
Stay alert and watch for trees, power lines, posts,
signs, and all other
obstructions while you are mowing. Use extreme
care to avoid hitting these types of obstructions.
