Great Plains Mfg., Inc. Section 1: Safety Rules
Safety Rules
Most accidents are the result of negligence and
carelessness, usually caused by failure of the
operator to follow simple but necessary safety
precautions. The following safety precautions are
suggested to help prevent such accidents. The
safe operation of any machinery is a big concern
to consumers and manufacturers. Your Finishing
Attachment has been designed with many built-in
safety features. However, no one should operate
this product before carefully reading this
Operators Manual.
General Operation & Repair
1. NEVER permit anyone near machinery while in
operation.
2. Excessive speed can cause machine damage.
3. NEVER allow anyone to be near the machine
when folding wings.
4. Reduce speed of the tractor when transporting
over uneven or rough terrain. Avoid all chuck
holes and washboard areas in roads.
5. Reduce speed of the tractor when transporting
over hills or steep slopes.
6. DO NOT lubricate, adjust or repair the machine
while it is in operation.
7. Use "Slow Moving Vehicle" emblem for warning
vehicles approaching from the rear.
8. DO NOT permit smoking, sparks, or an open
flame where combustible lubricants or liquids are
being used.
!
9.
! CAUTION! Escaping fluid under
pressure can have sufficient force to penetrate the
skin. Check all hydraulic lines and hoses
BEFORE applying pressure. Fluid escaping from
a very small hole can be almost invisible. Use
paper or cardboard, NOT BODY PARTS, to
check for suspected leaks. If injured, seek medical
assistance from a doctor that is familiar with this
type of injury. Foreign fluids in the tissue must be
surgically removed within a few hours or
gangrene will result.
Transporting
1. Use good judgement when transporting tractor
and implements on the highway. Always maintain
complete control of the machine.
2. Use warning flags or approved warning lights at
night and during other periods of poor visibility.
Do your best to prevent highway accidents.
3. When in transport, use accessory lights and
devices for adequate warning to operators of other
vehicles and use safety hitch chain. Comply with
all Federal, State and Local laws when traveling
on public roads.
4. Reduce speed of the tractor when transporting
over hills or steep slopes.
5. Reduce speed of the tractor when transporting
over uneven or rough terrain. Avoid all chuck
holes and washboard areas in roads.
Safety Decals
1. Your Finishing Attachment come equipped
with all safety decals in place. They were designed
to help you safely operate your Finishing
Attachment. Read and follow their directions.
2. Keep safety decals clean and legible.
3. Replace all damaged or missing safety decals. To
order new safety decals go to your Great Plains
Dealer and refer to the parts section for safety
decal package part number.

Section 2: Assembly & Set-Up Great Plains Mfg., Inc.
Assembly & Set-Up
This section covers the proper assembly of the finishing attachment. The reference numbers
on the figures give you an indication of the order of assembly. For a complete breakdown of any
part not shown in this assembly section, refer to Section 5 Parts, page 12, for proper location. Refer
to the Appendix, page 36, for proper bolt torque values.
Rolling Harrow Assembly
Your initial action is to bolt the drag
frame (1) to the rear drag plates located on the
rear of your Turbo Till as shown in Figure 1,
using 5/8 x 1 1/2 hex bolts (2) and secure with
lock washer and hex nut.
The rolling harrow gangs will come
pre- assembled. Mount the rolling harrow
mount brackets (3) to the under side of the drag
frames according to the dimensions in the
layout drawings starting on page 6, using 5/8 x
3 x 4 1/2 u-bolts (4) with a lock washer and
nut. You may tighten the u-bolts on all the
brackets. Attach the ball joint bracket (5) to the
rolling harrow assembly (6) using 5/8 x 3 x 4
1/2 u-bolts (7) with a lock washer and hex nut.
You may tighten the right bracket u-bolts, but
leave the left bracket u-bolts loose until the
rolling harrow assemblies are hung under the
frame. Now you may attach the rolling harrow
assembly (6) to the drag frame (1) using a 1x 4
hex bolt (8) using a nylon lock nut. Be careful
to put the proper gang in the proper location
and be sure that the assemblies are positioned
correctly as shown in the layout drawings
stating on page 16. When all gangs are hung
under the frame and positioned in the correct
location, tighten the remaining u-bolts.

Great Plains Mfg., Inc. Section 2: Assembly & Set-Up
Reel Following the Rolling Harrow Assembly
Mount the reel arm assemblies (1) to the
drag frames as shown in Figure 2, using the
dimensions in the layout drawings starting on
page 7, using a 5/8 x 3 x 4 1/2 u-bolt (2) with a
lock washer and hex nut. These bolts may be
tightened at this time.
Assemble the reel sub-assemblies (3) to
the reel arm assemblies (1) with 5/8 x 2 1/2 x 3
3/4 u-bolt (4), lock washer, and hex nut The
correct reel placement are shown in the
placement drawings, starting on page 16. If
you are assembling a 10’ or 12’ reel, you will
use 5/8 x 4 hex bolts (5), with lock washers and
hex nuts in center location as shown in figure 2.
If the reels between the center section and the
wing sections are closer than 5”, recheck the
reel arm dimensions and adjust accordingly.

Section 3: Operating Instructions 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 turbo-till is attached, raise and lower
the turbo-till 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 turbo-till.
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 turbo-till lift cylinders and remove
the transport locks.
2. For an initial starting point, set the pre-load on
the top nut on the reel arm assembly to 1/8”
from the top of the spring bolt to the top of the
3/4” lock nut.
3. Set the pre-load on the eye bolt to 1 1/2” from
the bottom of the eyebolt to the bottom of the
3/4 jam nut, this is also just an initial starting
point
4. You may need to adjust the eyebolt to change
the down pressure. Adjust the bottom 3/4 jam
nut closer to the bottom of the eyebolt for
more down pressure. You may need to adjust
the top lock nut spacing accordingly to raise
reel up for road clearance. Adjust the bottom
3/4 jam nut away from the bottom of the
eyebolt for less down pressure.

Great Plains Mfg., Inc. Section 4: Maintenamce & Lubrication
Maintenance & Lubrication
1. Always use the transport lock when
working or doing maintenance on the
turbo-till. 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.
7. Check the rubber spacers occasionally
located next to bearing flange and replace
if badly worn.
8. 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.
