Preparation and Setup
This section helps you prepare your tractor and 21122335SC seedbed conditioner for use, and covers tasks
that need to be done seasonally, or when the tractor/
Seedbed Conditioner configuration changes.
Before using the Seedbed Conditioner in the field, you
must hitch it to a suitable tractor, inspect systems and
level the Seedbed Conditioner. Before using the Seedbed
Conditioner for the first time, and periodically thereafter,
certain adjustments and calibrations are required.
Prior to Going to the Field Checklist
Complete this checklist before routine setup:
❑ Read and understand “Important Safety Informa-
tion” on page 1.
❑ Check that all working parts are moving freely, bolts
are tight, and cotter pins are spread.
❑ Make sure your tractor horsepower matches the
implement you are pulling. This is important so the
implement can do the best possible job.
❑ Clean all hydraulic couplings and connect to tractor
as shown on page 13 and 14.
❑ If machine is folded, remove the transport pins from
wing stops. (DO NOT remove pins if the wing is leaning against the pins or putting pressure on the pins.
Use the hydraulics to pull the wings in completely
before unpinning them.) Once the pins are removed,
slowly untold the unit. Make sure no one is under the
wings during the unfolding process.
❑ Check again for hydraulic leaks and watch that
hoses do not get pinched in hinges, wing stops, etc.
❑ After the machine is completely unfolded, raise and
lower the seedbed conditioner several times to purge
air from the hydraulic system. Again check for
hydraulic leaks and tighten or replace if necessary.
❑ Check safety chain hookup. Make sure all warning
lights are hooked up and functioning correctly.
❑ Check that all grease fittings are in place and lubri-
cated. See “Lubrication” on page 18. The hubs will
come pre-greased and will not need greased at this
time.
❑ Check that all safety decals and reflectors are cor-
rectly located and legible. Replace if damaged. See
“Safety Decals” on page 5.
❑ Inflate tires to pressure recommended and tighten
wheel bolts as specified. See “Tire Inflation Chart”
on page 21.
Spring Pre-load Adjustment
Refer to Figure 3
Note: Be sure shipping block is removed from each spring
assembly.
1. Loosen jam nut and set spring pre-load to 8 3/8” by
adjusting nut . Re-tighten jam nut .
2. Put transport locks in place and refold the machine
slowly. Put wing stop pins in place. Always use the transport pins when moving from field to field. You are now
ready to go to the field.

Hitching Tractor to Seedbed Conditioner
Crushing Hazard:
Do not stand or place any body part between Seedbed Conditioner and moving tractor. You may be severely injured or
killed by being crushed between the tractor and Seedbed
Conditioner. Stop tractor engine and set parking brake
before attaching cables and hoses.
To prevent soil compaction on rows, set tractor wheels
between rows. For hillsides and steep slopes, set tractor wheels as wide as possible for maximum stability.
1. Raise tractor three-point arms (if equipped) clear
up to clear Seedbed Conditioner.
2. For TWO-WHEEL DEIVE and MFWD tractors, pin
drawbar in fixed center position for field and transport. For FOUR-WHEEL DRIVE and TRAC-DRIVE
tractors, leave one hole clearance on each side of
drawbar for field position, hitch damage may occur
if pinned solid. Pin in center position for transport to
maintain maximum steering control.
Refer to Figure 4
3. Use jack to raise and lower Seedbed Conditioner
tongue.
4. Back tractor draw bar into alignment with hitch .
5. Secure with locking hitch pin.
6. Secure safety chain to an anchor on the tractor
or pulling implement.
Refer to Figure 5
7. After hitching tractor to Seedbed Conditioner, store
jack on storage tube on top of Seedbed Conditioner hitch frame.

Transporting
See “Hitching Tractor to Seedbed Conditioner” on
page 13 before transporting the Seedbed Conditioner.
Check Tractor Capacity and Configuration
• Know the weight of your Seedbed Conditioner (see
table on speciation page).
• Consult your tractor manual for 3-point limitations.
• Add weights to tractor as required.
When determining the weight of your Seedbed Conditioner, be sure to include the weight of any options.
Transport Checklist
❑ Plan the route. Avoid steep hills. Keep Clearances in
mind.
❑ Make all electrical and hydraulic connections. See
“Hitching Tractor to Seedbed Conditioner” on
page 13.
❑ Raise Seedbed Conditioner.
❑ Be sure all transport locks are installed.
❑ Always have lights on for highway operation.
❑ Comply with all federal, state and local safety laws
when traveling on public roads.
Travel with caution. Allow safe clearance.
Remember that the Seedbed Conditioner is wider than the
tractor.
Loss of Control Hazard:
Use a tractor rated for the load. Add tractor ballast as needed.
Do not exceed 20 mph. Towing the Seedbed Conditioner with a
vehicle that is not adequate, or at high speeds, could lead to
loss of vehicle control. Loss of vehicle can result in a serious
road accident, severe injury or death. Check that your tractor
has enough to handle the weight of the Seedbed Conditioner.
Refer to your tractor’s operator manual for capacities and ballast requirements.
General Operation and In-Field Adjustments
1. Remove the transport pins and unfold machine. Make
sure the fold cylinders are fully extended to allow the
wings to fully flex in the field.
2. If machine has the optional hydraulic down pressure
option, you will need a dedicated closed-center circuit
to the seedbed conditioner. Adjust the tractor flow rate
to the low side and engage the hydraulic lever for constant flow. For seedbed conditioners with Ser#
1001HH-1030HH, adjust the pressure reducing valve
to your conditions with a gauge reading of 600 to
900psi. The higher the pressure the more down pressure on the wing sections. For Serial#1031HH and
higher, See “Hydraulic Down Pressure (S/N
1031HH+)” on page 17 for setup instructions.
3. When turning around on end rows, it is ok to leave the
seedbed conditioner on the ground. The hitch pole
should be extended far enough to prevent the seedbed conditioner from contacting the host machine during turns.
540-072M 10/08/2013
Page 21
Great Plains Manufacturing, Inc. Operating Instructions 17
Hydraulic Down Pressure (S/N 1031HH+)
Refer to Figure 8
Note: Note: This setup procedure is for tractors with
closed-center or pressure compensated flow
hydraulic systems. Open center hydraulics not
supported.
4. Adjust the bypass/pressure reducing valve by turning
knob , Figure1, clockwise all the way in and then
1
backing out 1 full turn.
5. On tractor, adjust flow-control valve to low side of
flow rate.
Note: The faster the flow of oil through the system the
greater potential for oil heating, premature wear or
tractor damage.
6. Lock the fold hydraulic lever for continuous downward oil flow.
7. Adjust bypass/pressure reducing valve knob on
2
implement so the pressure gauge reads 1200 psi.
Never exceed 1400 psi.
8. While watching pressure gauge, slowly open valve
knob until gauge reads 1100 psi. Pressure might
1
rise and then fall off as knob is opened. If pressure
exceeds 1400 psi during this step, the tractor flow is
too high, reduce tractor flow. Lock valve knob at
1
1100 psi.
9. Finally adjust valve to the desired wing down pres-
2
sure setting of 300 to 400 psi. Never exceed 700 psi.
10. In field operation, Lock the fold hydraulic lever for
continuous downward oil flow. If wings are running
too high, increase pressure setting, knob , to level
2
machine. If center is too high, decrease pressure
setting with knob on valve.Never leave tractor
2
valve centered when unfolded with machine in
motion. Machine damage may occur when wings flex
up or down.
Never leave tractor valve centered when unfolded with

Maintenance and Lubrication
Maintenance
1. Always use the transport lock when working on or
doing maintenance to the seedbed conditioner. If
folded, be sure your wing stop pins are in place.
Read and understand all safety decals on your
equipment.
2. During the first season of operation check your bolts
for tightness.
3. Replace or rotate worn parts as needed -- hinge
bolts, clevis pins, bearings, etc.
4. Check and tighten or replace any hydraulic leaks.
Check hoses for any leaks. It is important that there
are no leaks on the equipment.
5. Check wheel bearings occasionally for excessive
endplay.
6. Grease wheel bearings sparingly. Over greasing
may cause damage to seals and reduce the life of
the bearing. Grease hinge points periodically. Reel
Bearings are maintanance free & do not require
greasing.
7. If machine is stored outdoors over the winter months,
it is a good idea to fold the machine then set it down
on the ground so all the cylinders are retracted to
protect the cylinder rods. This will extend the life of
the cylinder seals and reduce internal and external
leaks.
By following and maintaining a routine service and lubrication program, your tillage equipment will give you
many years of service.

Hydraulic Connectors and Torque
Refer to Figure 9 (a hypothetical fitting)
Leave any protective caps in place until immediately prior
to making a connection.
1
NPT - National Pipe Thread
Note tapered threads, no cone/flare, and no O-ring.
Apply liquid pipe sealant for hydraulic applications.
Do not use tape sealant, which can clog a filter and/or
plug an orifice.
2
JIC - Joint Industry Conference (SAE J514)
Note straight threads and the 37° cone on
“M” fittings (or 37° flare on “F” fittings).
Use no sealants (tape or liquid) on JIC fittings.
3
ORB - O-Ring Boss (SAE J514)
Note straight threads and elastomer O-Ring .
Prior to installation, to prevent abrasion during tightening, lubricate O-Ring with clean hydraulic fluid.
Use no sealants (tape or liquid) on ORB fittings.
ORB fittings that need orientation, such as the ell
depicted, also have a washer and jam nut
(“adjustable thread port stud”). Back jam nut away
from washer. Thread fitting into receptacle until
O-Ring contacts seat. Unscrew fitting to desired
orientation. Tighten jam nut to torque specification.
