PRELIMINARY SETTINGS
Proper preliminary and field settings will require
the use of a measuring device. Once the unit has
been properly assembled and hitched to the trac-
tor, make certain the hydraulic system as been
charged.
Position the unit on a level area of ground and
unfold the wings, checking to ensure that there
are no people or obstruction in the path of the
wings.
NOTE: Cycle the main lift hydraulic sys-
tem a number of times to remove air from
the circuit. Holding the hydraulic lever in
the "RAISE" position for a 1-2 minute pe-
riod should remove unwanted air.
Remove the stop collars from all cylinders and
turn the screw stop collars up to the clevis end of
the cylinders. Lower the unit so that the main
frame front shovels are 1"–2" above the ground.
Measure the frame height from the ground to the
top of the front main frame tube. Compare this to
the distance from the ground to the top of the rear
tube on the rear bar of the main frame. See Fig
11.

Level Main Frame - Front to Rear
Front to rear main frame level is adjusted by chang-
ing the setting of the clevis adjust rod above the main
lift cylinder. See Fig 7. Loosen the jam nut and turn
the threaded clevis adjust rod out of the main mast
tube. By increasing the length of the mast tube you
will lower the rear of the main frame. To raise the rear
of the main frame the main mast tube will need to be
shortened, turn the clevis adjust rod into the mast tube.
NOTE: If the clevis adjust rod is difficult to turn,
FRAME
lower the unit to the ground to remove the weight
HEIGHT
from the linkage.
Repeat this procedure on both sides of the main frame,
checking to ensure that the main adjust tubes are the
same relative length. Retighten the jam nuts on the
clevis adjust rods when the final settings are reached.
Level Wing Frame – Front to Rear
& Side to Side
Depending on the size of the main wing and type or
weight of any rear attachments you will need to ad-
just the front to rear level of the wings. In some situa-
tions either the front gauge wheel or rear axle can hold
the wing at a set depth. For setting purposes, loosen
the nuts at the gage tube adjust bracket at the front of
the wing tube and the jam nut on the adjuster rod. See
Fig 8. Measure the distance from the ground to top of
the rear tube at the outer rear corner of the wing. Com-
pare this to the distance set at the rear of the main
frame. If the rear of the wing needs to be raised, turn
the adjust rod (9.5) into the wing tube. If the rear of
the wing needs to be lowered, turn the adjust rod out.
When the rear distance on the wing matches the main
frame you can tighten the adjuster rod nut.
Measure the distance from the ground to the top of
the front tube at the outer front corner of the wing.
Again compare this to the distance measurement of
the front tube of the main frame. To raise the front of
the wing, lengthen the adjust rod at the gage tube ad-
just bracket. This will increase the length of the wing
tube/adjust bracket assembly and raise the front cor-
ner of the wing. Conversely, shorten or decrease the
adjust rod setting to lower the front corner of the wing.
Follow the same process to adjust the other wing. This
procedure should set both the front to rear and side to
side level of the unit.
