Unfolding the 7822 HSL

WARNING
Always unfold the 7822 on a level surface and
away from overhead power lines. Keep
bystanders and pets clear of the area.
1. Lift the 7822 with the two large transport tires by
extending the front gauge wheel cylinders (blue
circuit).
• Failure to do so may cause the wing frames to
interfere with the transport tires.
2. Tip the top of the center section rearward far enough
to lift the wing frames several inches above the wing
rest saddles located on the hitch. The center section
is tilted backward by extending the large cylinder
located over the hitch (red circuit).

CAUTION
Do not lift the wing assemblies more than a few
inches above the wing rest saddles when the
wing assemblies are folded forward.
3. With the wing frames above the wing rest saddles,
open the wing assemblies up until they are flat
across and aligned with each other.
• The wing assemblies are opened (unfolded) by
extending the wing fold cylinders (yellow circuit).
4. When the wing assemblies are aligned with each
other and flat across, extend the large tilt cylinder
located above the hitch, until the center and wing
assemblies are at rest on the ground.
The 7822 is equipped with a urethane draft cushion. This
creates a semi rigit hitch and allowes the machine to
adjust to undulations as the 7822 is pulled across the
field.
Folding the 7822 HSL

WARNING
Always fold the 7822 on a level surface and away
from overhead power lines. Keep bystanders and
pets clear of the area.

TABLE OF CONTENTS
2. Tilt the center section and wing assemblies up by
raising the rear of the HSL upward until it is near
completely upright.
• The center section is tilted upright by retracting
the large tilt cylinder located over the hitch (red
circuit).
3. Fold the wing assemblies forward by retracting the
wing fold cylinders (yellow circuit).
4. Tip the center section top rearward far enough to lift
the wing frames several inches above the wing rest
saddles located on the hitch. The center section is
tilted backward by extending the large cylinder
located over the hitch (red circuit).
5. With the wing assemblies just above the wing rest
saddles, further retract the wing fold cylinders to
position the wing assemblies over the wing rest
saddles (yellow circuit).
6. With the wing assemblies over the wing rest saddles,
lower the wing assemblies into the wing rest saddles
by further retracting the large tilt cylinder over the
hitch. Retract the large tilt cylinder until the wings are
at rest in the wing rest saddles (red circuit).
Synchronizing and Leveling
Front Gauge Points
The front gauge is comprised of the main wheels and
tires on the hitch frame and the gauge wheels and tires
on the wing frames.
NOTE
The 7822-15 wings unfold into a rigid configuration from
side to side.
The 7822-15 does not have gauge wheels and tires on
the wing assemblies.
IMPORTANT
Make sure the front gauges are synchronized and
leveled to enable the HSL to work the soil to uniform
depth of cut, across the entire machine.
The HSL has been adjusted prior to being shipped, but it
is appropriate to re-check it. Please consult the following
instructions and diagrams to check, or to re-set the
levelness of the front gauges should that become
necessary
NOTE
You will need the open end 2-5/8" wrench stored inside
the left wing frame, should adjustment be necessary.
Follow the steps below when setting the front gauges.
1. Unfold the 78252 on a relatively flat surface.
