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 bars
and secure bars on storage bracket. DO NOT drive
out transport bar pins. The wing cylinder may need to
be retracted to remove tension for bar removal. After
removing bars, extend wing hydraulic cylinders and
fully lower wings.
Wings are equipped with a floating link that allows 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.
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 bars to prevent wings from
inadvertently falling. NOTE: If the transport lock bars
can not be easily installed, lower the mower wings
and adjust the rod clevis in or out to match the transport
bar 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)
