4010 ATD LT ASSY/OPER/PARTS MANUAL (74303) 12/08
After the unit has been charged and levelled
it can be winged up to the transport position.
Make certain that the unit is hitched to a
tractor and setting on a level surface when
folding the wings. If possible, move the unit to
an area where the ground is not as hard but
has a loose composition. Move all personnel
away from the path of the wings but pay
attention to the components when folding.
Before folding the wings, raise the unit to full
height with the main lift circuit. Activate the
rear transport lift circuit and fully extend the
lift cylinders. Place the channel locks into
position on these rear transport cylinders.
With the front main lift wheel cylinders fully
extended manually remove the hair pin from
the latch rod (18) and rotate the main lift lock
down and latch to the extended lower pivot
pin. Place the latch rod into position to retain,
securing the front lift wheels into the transport
position.
NOTE: Channel locks must be locked
in position on the two rear transport lift
cylinders and the front main lift cylinders
must be secured before attempting to fold
the wings or transporting.
Once channel locks are in position, activate
the wing fold circuit and the wings should
began to fold. When folding for the fi rst time
pay attention to the movement of hydraulic
or feed hoses, it may require that hoses be
moved to prevent kinking or pinching. As the
inner wings began to fold the packer wheels
at the hinge point may skid. This should not
be a problem when folding the unit in loose
ground conditions. Skidding can be reduced
by slowly moving forward with the unit as
the wings are folded. Forward movement is
only required when the wing packer wheels
are skidding.
WING FOLDING/UNFOLDING
Continue to fold the inner wings, these wings
should fold to a slight over center position.
Once the wing have come to rest in the wing
rest clevis active the main lift circuit and pull
the packer wheels up. This is necessary to
allow clearance in the center of the unit and
reduce the transport width.
The front wing rest has provisions to lock
or pin the wing for transport. Insert the lock
pin into the rest clevis and secure with the
provided spring pins.
NOTE: The wings on this unit must be
locked before transporting or storing.
Insert the locking pin in the clevis on
the front wing lock. Make certain that
the wing is unlocked before attempting
to unfold the wings. Approach the wings
from the front when locking or unlocking
the wings, never go into the wing fold
path to lock or unlock the wings.
To unfold the wings reverse the process.
Fully extend the main fold cylinders after
unpinning the wings. Unfold the wings,
moving slowly forward as the packers on
the inner wing contact the ground. The main
frame and wing lift wheels and rear packer
wheels must be on the ground to support
the wings when they touch down.
Remove the transport channels from the
rear lift wheel cylinders and store. Unlock the
front main lift wheels cylinders by rotating the
latch arms up and pinning to hold parallel to
the top link arm..
NOTE: Do not allow personnel to walk
under a wing at any time while it is folding
or unfolding. Front gage wheels on the
wings can abruptly rotate as the wings
are folded.
