Transport Lock Braces
9.3 Operating the Mower Wings
Wings are positioned with hydraulic cylinders. It is recommended that the tractor be equipped with three hydraulic
ports or a 3-spool control valve be used so that each section can be controlled independently. Ensure the
hydraulic cylinders and lines are filled with oil by holding the valve control levers in the raised position until the
cylinders fully retract (wings) and extend (center). Only operate the mower with both wings fully lowered, NEVER
operate the mower with a raised wing. Wait until the blades are at a complete stop before raising wings.
Operating Position
To lower the wings, remove the transport lock braces
and secure braces on storage bracket. DO NOT drive
out transport brace pins. The wing cylinder may need
to be retracted to remove tension for brace removal.
After removing brace bars, extend wing hydraulic
cylinders and fully lower wings.
The valves operating wing cylinders should be placed
in the float position while mowing to allow the mower to
follow the contour of uneven terrain and to prevent the
wings from creeping up. When extending a wing over
a ditch for mowing, place the control valve lever detents
in the center position. This will give the mower more
stability and prevent the opposite wing from raising.
DO NOT operate the mower with the valves in the detent
position for extended periods of time to prevent deck
frame damage.
Transport Position
To raise mower wings, drive the unit to a level area and
retract the wing hydraulic cylinders. DO NOT raise
wings with the mower positioned on an embankment
or other inclined position to prevent overturning the
mower. After the wings are fully raised, install transport
lock braces to prevent wings from inadvertently falling.
NOTE: If the transport lock braces can not be easily
installed, lower the mower wings and remove rod end
of cylinder and adjust the rod clevis in or out to match
the transport brace length.
The center of gravity is raised and the mower more
prone to tipping when the wings are in the raised
position. When transporting, only raise the center
section high enough to clear ground obstacles.
DANGER!
When the Wings are folded for transport, the center of gravity is raised and the possibility of
overturn is increased. Drive slowly and use extreme caution when turning on hillsides.
Overturning the Implement could cause the Implement to overturn the Tractor and vice
versa resulting in serious injury or even death. Never fold wings on a hillside...the
Implement may overturn. (STI-2)
WARNING!
Use extreme care when lowering or unfolding the implement’s wings. Make sure no
bystanders are close by or underneath the wings. Allow ample clearance around the
implement when folding or unfolding the wings. Use extreme caution around buildings or
overhead power lines. (S3PT-5)
