Important Safety Information

Look for Safety SymbolThe SAFETY ALERT SYMBOL indicates there is apotential hazard to personal safety involved and extrasafety precaution must be taken. When you see thissymbol, be alert and carefully read the message that fol-lows it. In addition to design and configuration of equip-ment, hazard control and accident prevention aredependent upon the awareness, concern, prudence andproper training of personnel involved in the operation,transport, maintenance and storage of equipment.

Be Aware of Signal WordsSignal words designate a degree or level of hazard seri-ousness.

DANGER indicates an imminently hazardous situationwhich, if not avoided, will result in death or serious injury.This signal word is limited to the most extreme situations,typically for machine components that, for functional pur-poses, cannot be guarded.

WARNING indicates a potentially hazardous situationwhich, if not avoided, could result in death or seriousinjury, and includes hazards that are exposed whenguards are removed. It may also be used to alert againstunsafe practices.

CAUTION indicates a potentially hazardous situationwhich, if not avoided, may result in minor or moderateinjury. It may also be used to alert against unsafe prac-tices.

Use Safety Chains▲ Use safety chains to help control drawn machinery should it

separate from tractor draw-bar or trailing nurse tank hitch.

▲ Use chain with a strength rating equal to or greater thanthe gross weight of towed machinery.

▲ Attach implement chain to tractor draw-bar support orspecified anchor location. Allow only enough slack in chainfor turns.

▲ Replace chain if any links or end fittings are broken,stretched or damaged.

▲ Do not use safety chain for towing.

Avoid High Pressure FluidsEscaping fluid under pressure can penetrate the skin,causing serious injury. This Turbo-Chopper requires aPower-Beyond port, which is always under pressurewhen the tractor is running.

▲ Avoid the hazard by relieving pressure at other remote, andshutting down tractor before connecting, disconnecting orinspecting hydraulic lines.

▲ Use a piece of paper or cardboard, NOT BODY PARTS, tocheck for suspected leaks.

▲ Wear protective gloves and safety glasses or goggles whenworking with hydraulic systems.

▲ If an accident occurs, seek immediate medical assistancefrom a physician familiar with this type of injury.

Keep Riders Off MachineryRiders obstruct the operator’s view. Riders could bestruck by foreign objects or thrown from the machine.

▲ Never allow children to operate equipment.

▲ Keep all bystanders away from machine during operation.

Use Safety Lights and DevicesSlow-moving tractors and towed implements can createa hazard when driven on public roads. They are difficultto see, especially at night.

▲ Use flashing warning lights and turn signals whenever driv-ing on public roads.

▲ Use lights and devices provided with implement.

Preparation and Setup

This section helps you prepare your tractor and 1200-4000TC Turbo-Chopper for use, and covers tasks thatneed to be done seasonally, or when the tractor/Turbo-Chopper configuration changes.

Before using the Turbo-Chopper in the field, you musthitch it to a suitable tractor, inspect systems and level theTurbo-Chopper. Before using the Turbo-Chopper for thefirst time, and periodically thereafter, certain adjustmentsand calibrations are required.

Prior to Going to the Field ChecklistComplete this checklist before routine setup:

❑ Read and understand “Important Safety Informa-tion” on page 1.

❑ Check that all working parts are moving freely, boltsare tight, and cotter pins are spread.

❑ Make sure your tractor horsepower matches theimplement you are pulling. This is important so theimplement can do the best possible job.

❑ Clean all hydraulic couplings and connect to tractoras shown on page 14-16.

❑ If machine is folded, remove the transport pins fromwing stops. (DO NOT remove pins if the wing is lean-ing against the pins or putting pressure on the pins.Use the hydraulics to pull the wings in completelybefore unpinning them.) Once the pins are removed,slowly untold the unit. Make sure no one is under thewings during the unfolding process.

❑ Check again for hydraulic leaks and watch thathoses do not get pinched in hinges, wing stops, etc.

❑ After the machine is completely unfolded, raise andlower the Turbo-Chopper several times to purge airfrom the hydraulic system. Again check for hydraulicleaks and tighten or replace if necessary.

❑ Check safety chain hookup. Make sure all warninglights are hooked up and functioning correctly.

❑ Check that all grease fittings are in place and lubri-cated. See “Lubrication” on page 26. The hubs willcome pre-greased and will not need greased at thistime.

❑ 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 tightenwheel bolts as specified. See “Tire Inflation & War-ranty” on page 30.

❑ Put transport locks in place and refold the machineslowly. Put wing stop pins in place. Always use thetransport pins when moving from field to field. Youare now ready to go to the field.



Hitching Turbo-Chopper to TractorHitch to a tractor for highway transport or field opera-tions. Hitch to a leading implement only for field opera-tions. Do not transport behind another implement.

Before hitching, check the compatibility and capability ofthe towing tractor or implement:

• The 1200-4000TC Turbo-Chopper is a pull-typeimplement equipped with a standard Category IV sin-gle tang hitch. It may be converted to a Category III orclevis hitch using supplied accessory parts, see “Cle-vis Hitch” on page 16.

To prevent soil compaction on rows, set tractor wheelsbetween rows. For hillsides and steep slopes, set tractorwheels as wide as possible for maximum stability.

1. Raise tractor three-point arms (if equipped) clear upto clear Turbo-Chopper.

2. For TWO-WHEEL DRIVE and MFWD tractors, pindrawbar in fixed center position for field and trans-port. For FOUR-WHEEL DRIVE and TRAC-DRIVEtractors, leave one hole clearance on each side ofdrawbar for field position, hitch damage may occur ifpinned solid. Pin in center position for transport tomaintain maximum steering control.

Refer to Figure 23. Use jack to raise and lower turbo-chopper tongue.

4. Back tractor draw bar into alignment with hitch .

5. Secure with a locking hitch pin.

Negative Tongue Weight Hazard:Make certain that turbo-chopper is securely hitched to thetractor or leading implement before unfolding. An unhitchedturbo-chopper can tip over backwards during folding andunfolding if the tongue is not secured.

6. Secure safety chain to an anchor on the tractor.

Refer to Figure 37. Retract jack foot. Re-orient jack to storage position.

8. After hitching tractor to turbo-chopper, store jack onstorage stob on Turbo-Chopper tongue.

Load Sway Hazard:

9. Lock drawbar swing to center position to minimize anyside-to-side sway to assure proper tracking in the field,and safe road travel. See “Transport” on page 18, forsafe transporting.

Electrical HookupRefer to Figure 4Your Turbo-Chopper is equipped with North AmericanLights.

Plug the lighting connector into the tractor outlet.

Test the lights and signalling prior to highway movement.

Hydraulic Hose HookupGreat Plains hydraulic hoses are color coded to help youhookup hoses to your tractor outlets. Hoses that go to thesame remote valve are marked with the same color.

Hydraulic Hose Hookup

High Pressure Fluid Hazard:Shut down tractor before making hydraulic connections.Only trained personnel should work with system hydraulics.

Escaping fluid under pressure can have sufficient pressure topenetrate the skin causing serious injury. If an accidentoccurs, seek immediate medical assistance from a physicianfamiliar with this type of injury.

Use paper or cardboard, NOT BODY PARTS, to check forleaks. Wear protective gloves and safety glasses or goggleswhen working with hydraulic systems.

Refer to Figure 5To distinguish hoses on the same hydraulic circuit, referto hose label.

• The hose with an extended-cylinder symbol feeds acylinder base end.

• The hose with a retracted-cylinder symbol feeds acylinder rod end.

Secure hoses and cables so that they have sufficientslack for hitch movements, but cannot get caughtbetween moving parts of tractor, turbo-chopper or hitch.Failure to safely route and secure hoses and cablescould result in damage requiring component repair/replacement, and lost field time.

To distinguish hoses on the same hydraulic circuit, referto, “Hydraulic Hose Hookup” on page 15. Clean allhydraulic couplings and hook hoses to tractor.

Clevis HitchRefer to Figure 6The base hitch must be upright (with the recessed notchon the bottom) for this configuration. This places thetongue weight on the base hitch, and not the clevis.

1. Select one each: 890-798C HITCH CLEVIS 802-487C HHCS 3/4-10X6 GR8 803-367C NUT HEX TOP LOCK 3/4-10 PLT

2. With the square-shouldered end of the clevis up,fully seat the clevis in the upright base hitch .Insert the Grade 8 bolt from below. Secure withlock nut .

Hitch Failure Hazard:Install the hitch base and assemble the clevis parts as shown.Incorrect installation or assembly may result in failure of theclevis bolt, leading to hitch failure. This could result in a seri-ous highway accident or severe machine damage.

Category III HitchThe base hitch must be inverted (with the recessednotch on the top) for this configuration. Set theV-block to allow some vertical articulation of the drawbar pin. Always use at least one cushion .

1. Select one each: PPI-302V TOP PLATE - CAT 3 PPI-203VR V-BLOCK 802-383C HHCS 3/4-10X3 GR5

and two: PPI-205H CUSHION

2. Set the cushions inside the hitch recess , just for-ward of the vertical bolt hole. Position the V-blockforward of the cushions and check the size of theresulting pinning hole. Remove a cushion if needed.

Operating Instructions

This section covers general operating procedures. Expe-rience, machine familiarity, and the following informationwill lead to efficient operation and good working habits.Always operate farm machinery with safety in mind.

Pre-Start ChecklistPerform the following steps before transporting the 1200-4000TC Turbo-Chopper to the field.

❑ Carefully read “Important Safety Information” onpage 1.

❑ Lubricate Turbo-Chopper as indicated under “Lubri-cation” on page 26.

❑ Check all tires for proper inflation, “Tire Inflation &Warranty” on page 30.

❑ Check all bolts, pins, and fasteners. Torque asshown in “Torque Values Chart” on page 32.

❑ Check Turbo-Chopper for worn or damaged parts.Repair or replace parts before going to the field.

Check hydraulic hoses, fittings, and cylinders for leaks.Repair or replace before going to the field.

High Pressure Fluid Hazard:Relieve pressure and shut down tractor before connecting, dis-connecting or checking hydraulic lines. Use a piece of paperor cardboard, NOT BODY PARTS, to check for leaks. Wearprotective gloves and safety glasses or goggles when workingwith hydraulic systems. Escaping fluid under pressure canhave sufficient pressure to penetrate the skin causing seriousinjury. If an accident occurs, seek immediate medical assis-tance from a physician familiar with this type of injury.



Transport

Loss of Control Hazard:Do not tow the turbo-chopper behind another implement onpublic roads. Tow the turbo-chopper to the field with a sepa-rate vehicle. The leading implement may not provide sufficientlateral control of a trailing implement at highway speeds. Thetotal weight of the train can also exceed the steering and/orbraking capability of the tractor. The resulting accident couldcause serious injury or death.

Loss of Control Hazard:Use an adequate towing vehicle. Never tow an implement thatweighs more than 150% of the towing vehicle (transport vehi-cle must weigh at least 67% of implement). Ensure that thetowing vehicle is adequate for the task. Using an inadequatetow vehicle is extremely unsafe, and can result in loss of con-trol, serious injury and death.

See tables below for harrow transport weights.

Braking and Loss of Control Hazard:Do not exceed 20 mph (32 kph). Slow down on rough roads.

Transport StepsKnow your implement weight. If tractor capabilities aremarginal, check actual weight of implement at a scale.

1. Check that implement is securely hitched to a suffi-cient tractor (page 14).

2. Always use a locking-style hitch pin sized to matchholes in hitch and draw-bar, and rated for the load.

3. Attach safety chain to tractor with enough slack topermit turning (page 14).

4. Verify correct operation of lights.

5. Instal transport locks (page 20).

6. Check that tires are properly inflated (page 30).

7. Plan the route. Avoid steep hills.

8. Always have lights on for highway operation.

9. Do not exceed 32 kph (20 mph). Comply with allnational, regional and local laws when traveling onpublic roads.

10. Remember that the implement may be wider thanthe towing vehicle. Allow safe clearance.


Great Plains Manufacturing, Inc. Table of Contents Index Operating Instructions 19

Field OperationThis implement is designed to be pulled in the field withthe turbo-chopper engaged (including wide turns).Liftingfor short distances to clear residue clogs is acceptable.Lifting for tight turns or reverse moves is required.

Equipment Damage Risk:Lift for tight turns and reverse moves. Tight turns can result ina section moving backward. Never back up with harrows onthe ground. If the inside tire stops or rolls backward, the turn istight and requires lift.

21. Coulter springs are preset at 10 inches, giving thecoulters an initial operating force of 400 pounds. Thissetting is adequate for many no-till conditions. Forlighter no-till conditions where rocks or other obstruc-tions are a problem, you can lengthen the springs toprotect the coulters from impact

Note: Setting the coulter spring length shorter than 9.75”may contribute to premature failure of parts and voidsthe warranty. If additional force is needed, add weightsto the implement

Detracker Height Adjustment (Optional)Refer to Figure 12Note: Adjust detracker coulter springs like shown above,

See “Coulter Spring Adjustment” on page 21.

22. The initial height of the detracker coulter assemblies is 11/2” - 2” deeper than the machine gangs. To adjust theheight, loosen the set screws on the clamp shanksand slide the shank up or down to the desired height,then re-tighten set screws.

Note: May need to adjust coulter height for different field con-ditions.

23. Be sure all bolts are tightened to specs, See “TorqueValues Chart” on page 32.

General Operation and In-Field Adjust-ments24. Remove the transport pins, see “Transport Locks” on

page 20 and unfold machine. Make sure the fold cylin-ders are fully extended to allow the wings to fully flex inthe field.

25. Set the hydraulic down pressure using the instructions,see “Bypass Valve Adjustments” on page 24.

Never leave tractor valve centered when unfolded with machine inmotion. Machine damage may occur when wings flex. The hydrau-lic down pressure cylinders have no wing flex capability and oilflow is required when the wings flex up or down. You must have thetractor fold hydraulic lever in continuous downward flow or“float” position before the wings can flex over terrain in the raisedor lower lift position.

26. If possible have someone observe the machine duringfirst time operation for levelness—front to rear and wingsto center frame. Adjust each as needed. For front torear, either extend or shorten the length of the turn-buckle on the self-leveling system. Never run themachine with the back lower (deeper) than the front. Toadjust the machine from side to side, use the lift turn-buckle on each wing

27. For best results, if at all possible, run the machine at aslight angle to the rows. This will improve trash flow andhelp spread the residue more evenly throughout thefield.

Depth StopRefer to Figure 13

28. When you have machine level and set to the desiredworking depth, set the depth stop on the depth stoptube . This is located at the front of the machine. Thiswill maintain a constant depth each time after raisingand lowering machine.One full turn of the handle willchange the depth approximately 1/4”.

Note: Slight tire to ground pressure should be maintainedto prevent cylinder pin and clevis wear. If after settingthe depth stop, the detent on the tractor kicks out be-fore the stop contacts the button on the depth stop,slow the hydraulic flow speed down. If this problemexists, contact the factory service representative forother possible adjustments. On tractors with a timeddetent setting, set the detent so when you raise themachine, the pump will run for 1/2 to 1 full second af-ter full raise. If it runs longer than this, damage to theseals of the lift cylinders may result.

Spike DragRefer to Figure 14

29. Adjust the drag to leave the desired results while main-taining the trash flow through the drag.

30. On the spike drag, start with 5 links hanging from thechain in drag arm bottom slot. (This is the starting pointfor worst conditions.) The cleaner the ground, theshorter the pull chain may be pulled up. On the spikedrag, one of the links in the first row of angles is turnedover. This allows the trash to start flowing through thedrag easier by changing the angle of the first row ofteeth. Always make sure that the drag is never pulling offthe hang chains. If so, shorten pull chains.

ReelRefer to Figure 15

31. If a basket is added, adjust the amount of down pres-sure by either shortening the eyebolt for less pressureor lengthening the eyebolt for more pressure.

Be sure reels are installed with twisted bars oriented forward asshown. Mounting backward can damage reel in rocky soil.

Bypass Valve Adjustments

1800-3000 Hydraulic Down PressureRefer to Figure 16Note: Note: This setup procedure is for tractors with closed-

center or pressure compensated flow hydraulic sys-tems. Open center hydraulics not supported. Adjustdown pressure valve as shown on decal (locatedon front of left side of center frame) Refer to Figure 17.

Never leave tractor valve centered when unfolded with machinein motion. Machine damage may occur when wings flex up ordown

This machine is designed for continuos hydraulic flow to the wingfold cylinders during field operations. It is for use on tractorshaving CLOSED CENTER hydraulics only. If your tractor has anOPEN CENTER hydraulics, please consult your dealer for oper-ating instructions.

32. Adjust the bypass/pressure reducing valve by turningknob , clockwise all the way in and then backing out1 full turn.

33. On tractor, adjust flow-control valve to low side of flowrate.

Note: The faster the flow of oil through the system the great-er potential for oil heating, premature wear or tractordamage.

34. Lock the fold hydraulic lever for continuous downwardoil flow.

35. Adjust bypass/pressure reducing valve knob onimplement so the pressure gauge reads 1200 psi.Never exceed 1400 psi.

36. While watching pressure gauge, slowly open valveknob until gauge reads 1100 psi. Pressure mightrise and then fall off as knob is opened. If pressureexceeds 1400 psi during this step, the tractor flow istoo high, reduce tractor flow. Lock valve knob at1100 psi.

37. Finally adjust valve to the desired wing down pres-sure setting of 300 to 400 psi. Never exceed 700 psi.

38. In field operation, Lock the fold hydraulic lever for con-tinuous downward oil flow. If wings are running toohigh, increase pressure setting, knob , to levelmachine. If center is too high, decrease pressure set-ting with knob on valve.Never leave tractor valvecentered when unfolded with machine in motion.Machine damage may occur when wings flex up ordown.

Maintenance and Lubrication

Maintenance1. Always use the transport lock when working on or

doing maintenance to the Turbo-Chopper. If folded,be sure your wing stop pins are in place. Read andunderstand all safety decals on your equipment.

2. During the first season of operation, and periodicallyafter that, check your bolts for tightness. Checkshank pivot bolts for tightness. Check shank pivotbolts on the spring-loaded shank, these must remaintight to prevent excessive wear on the shank assem-bly.

3. Replace or rotate worn parts as needed -- hingebolts, clevis pins, bearings, coulters, etc.

4. Check and tighten or replace any hydraulic leaks.Check hoses for any leaks. It is important that thereare no leaks on the equipment.

5. Grease wheel bearings and walking beams spar-ingly. Over greasing may cause damage to seals andreduce the life of the bearing. Grease hinge pointsperiodically.

6. Check drag bolts for loosness or excessive wear.Replace broken or bent teeth. Your drag is an impor-tant part of the tillage operation.

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 toprotect the cylinder rods. This will extend the life ofthe cylinder seals and reduce internal and externalleaks.

By following and maintaining a routine service and lubri-cation program, your tillage equipment will give youmany years of service.
