Final Inspection Check off
Paint touch ups complete
No hydraulic leaks
Transport circuit with sequence valve is functioning properly. During
fold-up, transport cylinders fully retract before boom wheels turn.
During unfold, boom wheels turn completely before transport cylinders
extend. (Sequence valve may need to be adjusted for different tractors)
Tine angle circuit is functioning properly. Cylinders on all sections
extend and retract evenly.
Operators manual is with machine.
Cable wing stop assembly is installed so that the cable is tight
diagonally across the sections and all the slack is between sections
behind the knuckle.
Ensure safety lights function correctly - Left & Right signals work correctly
locking arms lock when unfolding the unit
Preform fold/unfold. (see Sequence valve adjustment on following
pages or Operators manual if adjustment is needed)
CHECKED BY:
IMPORTANT: Initial hydraulic pressure of the tractor will need to be
2900 psi or higher for sequencing to occur properly. IF harrows do not
fully raise make sure tractor has at least 2900 psi before adjusting the
sequence valve.

5.2 Transport Sequence Valve
This harrow bar is equipped with rotatable wing
boom wheels that are used for both field and
transport orientations. The rotation also provides
the operator with a method to steer the wings
outward during unfolding for easier, quicker, and
more compact unfolding.
The wing boom wheel cylinders and transport
lift cylinders are on the same hydraulic circuit,
controlled by a sequence valve. The sequence
valve ensures the correct order when folding or
unfolding the unit:
1. During fold, the transport lift cylinders must
retract fully (lift the bar) before the wing boom
wheels can turn into transport position.
2. During unfold the wing boom wheels must
turn fully into field position before the
transport lift cylinders can extend to lower the
bar.

5.2.1 Adjusting the sequence valves
In the scenario that the transport circuit is not
sequenced properly, the valves can be adjusted
to correct the problem. The transport hydraulic
manifold is located on the harrow cart and contains
2 sequence valves, one for folding and one for
unfolding. Use the table below to determine the
required adjustment.
To adjust the sequence valves:
1. Locate the correct valve as per the table .
2. Remove the plastic cap from the end of the
valve to expose the adjustment screw.
3. Loosen the 9/16” locking nut on the valve.
4. Turn the 5/32” hex socket screw clockwise
(in) to increase the valve pressure or counter-
clockwise (out) to decrease the valve pressure.
Turn only ½ of a revolution at a time.
5. Re-check the function of the valves after every
½ turn.
6. Once properly adjusted, tighten locking nut and
return plastic cap to protect threads.
Operation Problem Solution
Fold Wing boom wheels turn before bar is fully raised Increase pressure of SCCA valve
Wing boom wheels don’t turn or turn excessively slow Decrease pressure of SCCA valve
Unfold Bar lowers before wing boom wheels are fully turned Increase pressure of SCEA valve
Bar won’t lower or lowers excessively slow Decrease pressure of SCEA valve

Symptom Probable Cause Solution
Cannot adjust tine angle to a more
aggressive position Too much draft force on the tines
Temporarily reduce ADF pressure or
stop harrowing. Adjust as required.
Return to previous settings.
Tine angle is uneven from section
to section Tine angle hydraulics are out of phase
Rephase tine angle hydraulics by
extending tine angle cylinders and hold
remote for several seconds before
readjusting.
Boom wheel lock valve is closed Open boom wheel lock valve.
Sequence valve is not adjusted properly See section 5.2.1 for adjustment
instructions
Transport lock pins are still in place Remove transport lock pins
Sequence valve is not adjusted properly See section 5.2.1 for adjustment
instructions
Wing booms are too far forward
compared to the cart.
Drive forward until boom will begin to
fold down. If auto-fold arms come out
of latches, tip boom down only slightly
then drive backward before continuing
to unfold.
Auto-fold lataches do not engage
over the auto-fold arms when
putting unit into field position
Auto-fold arm is set at improper angle
Adjust the angle by adding or removing
shim plate behind the arm pivot
mounting plate.
Auto-fold arms become
disengaged when adjusting the
main transport lift
The transport latches will disengage auto-
fold arms when wings are lifted.
Move the transport latch cable from the
bottom hole to the top hole on the
center boom prior to operaton. Refer to
section 4.10.3.
Cable in windrow position. Move cable position. Refer to section
4.10.3.
Excessive stretch in cable. Adjust cable length.
Transport fold or unfold happens
out of sequence
Boom will not fold down out of
transport position
Auto-fold arms do not disengage
when put into transport position

9.2 Transport Sequence Manifold
The transport sequence manifold combines the
functions of the transport lift cylinders and the
wing boom wheel cylinders and forces the two
functions to occur in the correct order during fold
or unfold. This eliminates the chance for incorrect
order that would cause damage to the machine.
The valves within this manifold can be adjusted
as per Section 5.2.1, or changed out if they are
malfunctioning.
9.2.1 Fold Sequence Cartridge
The cartridge labeled SCCA is necessary for
machine fold. It forces the transport lift cylinders
to retract fully before the boom wheels can be
turned into field position.
9.2.2 Unfold Sequence Cartridge
The cartridge labeled SCEA is necessary for
machine unfold. It forces the wing boom wheels
to turn fully into field position before the transport
lift cylinders can lower the bar.
9.2.3 Check Valve Cartridge
The CKEB pilot operated check valve is an added
measure to ensure proper sequencing during
unfolds. The machine can sometimes be oriented
such that there is a tensile load on the transport
lift cylinders. The check valve locks oil to the rod
side until the SCEA sequence valve opens allowing
the check valve to pilot open as well.
