9.3 Operating the Mower Wings
Wings are positioned with hydraulic cylinders. 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 pins and secure pins at storage location. DO NOT drive out
transport pins that have tension on them. After removing pins, extend wing hydraulic cylinders and fully lower
wings.
Wing hydraulic control valves should be set in the float detent during operation 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 for greater stability.
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 pins to prevent the wings and center section from
inadvertently falling.
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.
