4010 ATD LT ASSY/OPER/PARTS MANUAL (74303) 12/08
Check the front to rear level of the main
wings. As noted below the measured distance
between the shank and the ground should
be the same as the main frame. To adjust
the level front to rear both the front lift wheel
and rear packer can be adjusted. Check the
distance at the front outside shank location on
the wing versus the height of the main frame.
If the front of the wing needs to be altered,
loosen the jam nuts on the front adjust screw
and adjust as required. Once the front of the
wing is at the same depth as the main frame,
lock the front into position. Measure the rear
shank height and adjust the rear packer
adjust anchor as required.
As with the main frame, lower the unit to
relieve the load on the various anchors to
allow easier adjustment,

Once the adjustments to the various anchors
have been completed there should be minimal
need to readjust these settings. When the unit
has been moved to the fi eld and dropped to
the seeding depth it is important to recheck the
front to rear level and depth of each section.
Variations in soil type and loading will effect
the operational depth and readjustments may
be required.
The adjustments noted above are to level
the unit.
To control the seeding depth the
stop collars on each lift cylinder must be
changed.
A full set of color coded stop collars
of varying thickness is provided for each lift
cylinder. Use these stop collars to set the
seeding depth of the unit. If the seeding depth
is too deep, stop collars need to be added
to each cylinder.
The cylinders have been
sized to allow the addition or removal of
the same thickness of stop collars from
each cylinder to control depth of seeding.
For example: if the unit is seeding deep all
cylinders would have a stop collar of the
same color added. As the unit is cycled it may
require that the lift system be re-sequenced.
Raise the unit and hold the cylinders in the
extended position until all cylinders have
