Section 3: Operating Instructions Table of Contents ► Great Plains Mfg., Inc.
Operating Instructions
Prior to Going to the Field
1. Both dealer and customer read and
thoroughly understand all safety
recommendations. (These are found in the
Safety Section of this operator manual.)
2. Make sure your tractor horsepower matches
the implement you are pulling. This is
important so the implement can do the best
possible job.
3. Clean all hydraulic couplings and connect to
tractor or host implement. Each hydraulic
coupling has a colored handle on it and is
marked with a cylinder, either extending or
retracting.
4. After the seedbed conditioner is attached,
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.
5. Check the tire pressure for proper inflation
and check the tightness of the lug bolts. Tire
pressure information can be found in the
Appendix of this manual.
6. Check for any bolts that may need tightened
or retightened. Grease all the hinge points.
The hubs come pre-greased and will not need
more grease at this time.
7. Prior to transporting, fully raise the seedbed
conditioner. Install the transport locks. Always
use the transport locks when moving from
field to field in case of a hydraulic hose failure.
You are now ready to go to the field.
General Operating Instructions and In-Field Adjustments
1. Extend the seedbed conditioner lift cylinders
and remove the transport locks.
2. Set the pre-load on the ridge splitter shanks to
12 1/4” spring length.
3. Check the pre-load on the seedbed
conditioner baskets to 8 3/4” spring length.
4. The seedbed conditioner should be raised
with the host implement when turning.

Great Plains Mfg., Inc. Table of Contents ► Section 4: Maintenamce & Lubrication
Maintenance & Lubrication
1. Always use the transport lock when
working or doing maintenance on the
seedbed conditioner. Read and
understand all safety decals on your
equipment.
2. During the first season of operation, and
periodically after that, check your bolts for
tightness.
3. Check wheel bearings occasionally for
excessive endplay.
4. Replace or rotate worn parts as needed—
bolts, clevis pins, bearings, chisel points
etc...
5. Check and tighten or replace any
hydraulic leaks. Check hoses for any
leaks. It is important that there are no
leaks on the equipment.
6. Grease reel bearings and wheel
bearings sparingly. Over greasing may
cause damage to seals and reduce the
life of the bearing. Grease hinge points
periodically.
Reel Bearings
Grease every 50 hours (sparingly).
7. If machine is stored outdoors over the winter
months it is a good idea to retract the
cylinders 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 attachment will
give you many years of service.
For more information on operating, adjusting
or maintaining your Great Plains Verti-Till
Attachment contact your local Great Plains
dealer or call
Great Plains Mfg. at (800) 255-9215
Wheel Bearings
Grease every 50 hours (sparingly) and
check for endplay.
Caster Wheels Pivots
Grease every 10 hours.
