MANDATORY SAFETY SHUTDOWNPROCEDURE

BEFORE unclogging, cleaning, adjusting,lubricating or servicing the unit:

ADDITIONAL SAFETY REMINDERSIt is recommended that the towing tractor be equippedwith an enclosed operator’s cab.

Some photographs, used in this manual, may showDoors, Guards and Shields open or removed for illustra-tion purposes ONLY. BE SURE that all Doors, Guardsand Shields are in their proper operating positions andsecurely attached BEFORE operating unit.

BE SURE the Hitchjack Locking Pin is completelyengaged and that the machine is properly blocked andprevented from rolling BEFORE disconnecting the unitfrom the tractor!

ALWAYS follow state and local regulations regardinguse of a safety chain and transport lighting when towingfarm equipment on public highways. Restrict highwaytowing speeds to 20 mph (32 kmh) maximum. BESURE to check with local law enforcement agencies foryour own particular regulations. Unless otherwiseprohibited, use a Slow-moving Vehicle Emblem.

Only a safety chain (NOT an elastic or nylon/plastic towstrap) should be used to retain the connection betweenthe towing and towed machines, in the event ofseparation of the primary attaching system.


SAFETY(Continued)

ALWAYS wear safety glasses with side shields whenstriking metal against metal. It is further recommendedthat a softer (non-chipable) material be used to cushionthe blow. Failure to heed could lead to serious injury tothe eye(s) or other parts of the body.

Good safety practice dictates that you NEVER tow animplement (without brakes), unless towing vehicleweighs at least one-and-one half (1-1/2) times theweight of the towed implement and its load. For anypublic highway travel and to be in compliance with thisrule, BE SURE that your tractor is heavy enough tocounterbalance the weight of the Disc Conditioner.

Our Company does NOT sell replacement tires. Inaddition, tire mounting, service or inflation can bedangerous. Whenever possible, trained personnelshould be called to service and/or mount tires, followingthe tire manufacturer’s instruction. If you do NOT havesuch instructions, contact your tire dealer or ourCompany. In any event, to avoid possible fatal or seriousinjury, follow the specific directive given in thePreparing for Field Operation chapter of this manual.

Fields to be mowed must be free of foreign objects.Keep people 100 feet (30 m) or more away from unitduring operation. Do not engage PTO unless unit is inoperating position.

BE SURE to alsoswing the Drawbar to the Transport position and placethe Transport Lock Valve in “closed” Position.

NOTE: DO NOT operate the PTO when theDisc Mower Conditioner’s Drawbar (Tongue) is inthe Transport Position. This position puts anexcessive load angle on the Rear Drive Joint. Thisexcessive load angle will cause prematurecomponent wear.


CHAPTER 6OPERATION

CAUTIONBEFORE starting the tractor engine andrunning the Disc Mower Conditioner for thefirst time, review and comply with ALLSAFETY recommendations set forth in theSAFETY chapter of this manual.

EMERGENCY SHUTDOWNIn an emergency or in case a foreign object enters theHeader area, STOP cutting material IMMEDIATELYby disengaging the tractor PTO. Then, exercise theMANDATORY SAFETY SHUTDOWN PROCE-DURE (page 8) BEFORE leaving the tractor seat toremedy the problem.

START-UP

CAUTIONBE SURE ALL factory installed Guards andShields are properly secured in placeBEFORE starting the tractor engine. Becertain that NO people are within 50 feet of theunit when engaging the PTO.

To avoid unnecessary strain on the Disc MowerConditioner Drive Line components, ALWAYS engagethe tractor PTO slowly with the tractor engine at lessthan half throttle. Bring the unit to PTO speed BEFOREstarting to cut. Always operate at PTO speed!Attempting to operate at higher than PTO speed couldcause excessive vibration, wear and early componentfailure. In addition, operating the unit at slower thanPTO speed will cause poor windrow formation andincrease the chances of plugging.

STARTING THE FIELDNOTE: BEFORE proceeding to cut, raise andlower the Header a couple of times to insure that itis operating properly.After the field has been checked and is known to be freeof obstructions, it can be opened by cutting the firstswath in a counterclockwise direction. However, it isrecommended to make two or three clockwise roundsfirst to expose any potential hazards around the edge ofthe field. Then, proceed to cut and condition thebackswaths by operating in a counter-clockwise

direction around the field. The field can then be dividedinto sections, as desired.

GROUND SPEEDThe Disc Mower Conditioner can be operated in a widerange of ground speeds depending on crop conditionsand/or terrain. Any change in ground speed should bemade by changing tractor gears and NOT by increasingor decreasing tractor engine RPM.

UNPLUGGINGIt is possible for the Disc Mower Conditioner to plug intwo different areas. It can become plugged in the Discarea slipping the Drive Line Clutch, or the unit canbecome plugged in the Conditioning Rolls causingBandbelt to slip.

Plugged DiscsTo clear a plugging condition in the area of the Discs:1. Shut off the PTO.

2. Raise the Header all the way up.

3. Exercise the MANDATORY SAFETY SHUT-DOWN PROCEDURE (page 8) and lock thetractor parking brake.

4. Engage both Header Transport Locks.

5. Carefully clear the plug from the Cutterbar area.

6. If the plugging occurs frequently, refer to theTroubleshooting chapter for additional directives.

Plugged Conditioning RollsTo clear plugging from the Conditioning Rolls, proceedas follows:NOTE: If either the Conditioner Drive Belt orSlip Clutch starts to slip, stop forward travel anddisengage the PTO IMMEDIATELY!1. Stop forward movement of the tractor and

disengage the PTO.2. Raise the unit up fully.3. Exercise the MANDATORY SAFETY SHUT-

DOWN PROCEDURE (page 8) and lock thetractor parking brake.

4. Engage both Header Transport Locks.5. Open Front Cover on Header and remove excess

material. Turn Cutterbar Disc in a reverse direc-tion to back out the plug from between the Rollers.

6. If the plugging occurs frequently, refer to Trouble-shooting chapter for additional information.

HILLY CONDITIONSUnder hilly conditions, it is necessary to add a 95%calcium chloride solution to the left tire for additionalstability.


CHAPTER 7ADJUSTMENTS

CAUTIONBEFORE proceeding to perform any adjust-ments on this unit, exercise the MANDATORYSAFETY SHUTDOWN PROCEDURE (page 8).

The DC2340 and DC2360 Disc Mower Conditionershave been designed and factory adjusted to functionproperly under most field operating conditions.However, due to the wide range of operating conditionsencountered, some additional readjustments may berequired.

CAUTIONBEFORE proceeding to adjust the cuttingheight, exercise the MANDATORY SAFETYSHUTDOWN PROCEDURE (page 8).

HEADER FLOTATION(Figs. 6 & 7)

NOTE: BE SURE to place the Header in theoperating position before proceeding to adjust theflotation. In addition, when operating the DiscMower Conditioner with a high PTO horsepowertractor, the flotation may have to be set heavier onthe left side of the Header to counteract the higherrotational torque’s tendency to lift the Header offthe ground.

The Header flotation is adjusted by varying the settingof the Flotation Springs on each end of the Header.Lower the Header to the operating position, loosen theJam Nuts and tighten or loosen the Spring Bolts toachieve the desired flotation. For normal conditions, theflotation should be set with enough force to just lift eachend of the Header off the ground. In rocky or roughconditions, the flotation should be set lighter to protectthe Cutterbar. At higher mowing speeds, heaviersettings follow terrain better.

NOTE: Any change of cutting height or Drawbarheight will change the Header flotation. BE SUREto readjust the flotation, if necessary, to avoiddamaging the Cutterbar Knives. Also, whenmaking a flotation adjustment to the left side of theHeader, BE SURE to adjust both Springs evenly, toavoid damaging the U-bolt Anchor on the bottomend of the Springs.

DISC ANGLE (Fig. 8)The Disc angle is infinitely adjustable from 3° down (4″,102mm cutting height) to 10° down (1-1/2″, 38mmcutting height). In rocky or rough conditions, use aflatter or 3° Disc angle to protect the Disc Blades. Indown, tangled and lodged crops, use a steeper or 10°Disc angle to obtain a clean cut.

CAUTIONRaise the Header, exercise the MANDATORYSAFETY SHUTDOWN PROCEDURE (page 8)and install the Transport Locks BEFOREproceeding to adjust the Disc angle.

To change the Disc angle, it is necessary to move the rearpivot of the third Link forward (10°) or backward (3°).To adjust the Disc angle, loosen the Crossbolt and usethe Adjustment Nuts to make the desired change.

NOTE: A Disc angle change will change theHeader flotation. To avoid damage to the Discs orBlades, BE SURE to readjust the Header flotationafter changing the Disc angle.

SKID SHOES (Fig. 9)The Skid Shoes are located on the underside of theCutterbar Frame and are NOT adjustable.

CONDITIONER ROLL PRESSURE(See Fig. 10)

The Conditioner Roll pressure determines the amount ofconditioning done to the crop (assuming the Roll gap isproperly adjusted) and should be used accordingly.

For crops like alfalfa and clover (legumes), use onlyenough Roll pressure to crack and kink the stems. If theleaves show dark spots and/or the tops of the plants arebeing clipped off, too much Roll pressure is being used.

In grass-type crops, more Roll pressure is required thanfor legume-type crops.

NOTE: If the Conditioner Rolls are separatedtoo far, there is NO amount of Roll pressure that willdo a satisfactory job, in most crop conditions.


Adjust Conditioner Roll Pressure Spring by adjustingthe threaded Turnbuckle and Rod system. Springpressure is normally adjusted from the factory at 48″(1220mm) overall Spring length including hooks. MoveTurnbuckle Ends together to increase Roll pressure. DONOT overtighten! Prevent Spring Rods from rotating asTurnbuckle is tightened. Lubricate threads to easeadjustment.

Once Spring pressure is set, change amount of cropconditioning by varying Roll spacing. Greater Rollspacing results in less crop conditioning while less Rollspacing results in greater crop conditioning.

NOTE: Do NOT reduce the Roll pressure to thepoint where there is NO Spring force on the Rolls.Damage can occur to the Roll Pressure Chain, ifthe Roll pressure is too low, allowing the Rolls toopen and close freely.

CONDITIONER ROLL GAP(See Fig. 11)

The Conditioner Roll gap is the distance between the topof the lug on one Roll and the root of the lug of themating Roll. The Roll gap should be set from 1/16 to1/8″ (1.6 to 3.2mm), for most crops. However, it may bedesirable to increase the Roll gap, when cuttingthick-stemmed cane-type crops.

NOTE: Always check the Roll gap at severalpoints along the entire length of the Rolls and atevery 90° of rotation. The gap must always bemaintained at a minimum of 1/16″ (1.6mm).Operating at closer than this minimum gap or withRolls touching will result in damage to theConditioner Rolls, Bearings and Frame.

The Conditioner Roll gap can be changed by adjustingthe Stop Bolt at each end of the Header. First loosen theLocking Jam Nut. Turning the Stop Bolt into the Headerwill open the Rolls increasing the gap. Turning the StopBolt out will close the Rolls decreasing the gap. BESURE to retighten the Locking Jam Nuts after thedesired gap has been set.

NOTE: If the Conditioner Rolls are separatedtoo far, there is NO amount of Roll pressure that willdo a satisfactory job of conditioning, in most crops.

TOP ROLL CHAIN DRIVE TENSION(Fig. 11)

The Roll Drive Chain is tensioned by a Spring on theRoll Chain Idler. This Spring tension is NOT adjustable.

NOTE: When the Spring no longer puts tensionon the Idler, replace the Roll Drive Chain.

CHAPTER 8LUBRICATION

GENERAL INFORMATION

CAUTIONNEVER attempt to lubricate the machine whenany part of the unit is in motion. ALWAYS, BESURE to exercise the MANDATORY SAFETYSHUTDOWN PROCEDURE (page 8), BEFOREproceeding to lubricate the machine.

It is well to remember that a sufficient amount of oil orgrease will prevent excessive part wear and earlyfailure.

CUTTERBAR

NOTE: The oil in the Cutterbar MUST bechanged after the first 10 hours of operation.

It is difficult to accurately check the oil in the Cutterbar.If in doubt as to the amount of oil contained in Cutterbar,do NOT add oil. Drain and refill the Cutterbar. The oilshould be changed every 200 hours or at least annually(more often if operated under heavy loads). TheCutterbar MUST be drained completely so that the exactvolume of oil required can be put back into theCutterbar. The following procedure MUST befollowed:

1. Operate the Disc Conditioner for 10 minutes sothat the Cutterbar reaches operating temperature.

2. Raise the Disc Conditioner to the transportposition and engage the Transport Locks.

3. Park the Disc Conditioner so that the left rearcorner of the Cutterbar is the lowest point on theCutterbar.

4. Exercise the MANDATORY SAFETY SHUT-DOWN PROCEDURE (page 8).

5. Remove the Skid Shoe from the left end of theCutterbar. Remove the Overflow Plug from thebottom of the Cutterbar and the Filler Plug locatedbetween the second and third Disc on top of theCutterbar. Allow the oil to drain completely. Waitfor the dripping to stop.

6. Reinstall the Overflow Plug and the Skid Shoe.Refill the Cutterbar with SAE 80 GL 4 oil(DC2340, 7 Disc Cutterbar, 4 pt, 1.9 L) (DC2360,8 Disc Cutterbar, 4–1/2 pt, 2.13 L).

NOTE: In some areas SAE 80 GL 4 oil maynot be available. A GL 4 or GL 5 grade SAE#80W90EP Gear Lube is an acceptable substitute.

The Cutterbar should be checked daily for oil drips anddust accumulation around the Seals. Oil drips or dustaccumulation indicate that the Seals are leaking. Oilwhich is tan in color and foams excessively indicatesthat it has water present.

NOTE: There will be signs of oil at the OverflowPlug. A small amount of oil in this location shouldbe considered normal.

GEARBOX (CHECK DAILY)A Dipstick is provided for checking the oil level in theGearbox. The correct oil level range is between thebottom line and top line on the Dipstick when theCutterbar angle is less than 5° or cutting height 3 to 4″(76 to 102mm). For cutting angles of from 5° to 10°, thecorrect oil level range is between the bottom line andNOT MORE than 3/4″ (19mm) above the top line on theDipstick. The oil should be changed every 200 hours ofoperation or annually (more often if operated underheavy loads). The gearbox holds 4.8 qts (4.5 L) of SAE#80W90EP Gear Lube.

The Gearbox should be checked occasionally for oildrips and dust accumulation around the Seals. Oil dripsor dust accumulation indicate that the Seals are leaking.Oil which is tan in color and foams excessively indicatesthat it has water present.

NOTE: The oil in the Gearbox MUST bechanged after the first 10 hours of operation.


OILING (CHECK DAILY)(See Fig. 13)NOTE: When checking Roller Chain Oil Bath oillevel, MAKE SURE to remove all debris from thewater drain holes in the Conditioner Roll Springcompartment.The Roller Chains are enclosed and oiled in a sealed OilBath on the right side of the Disc Conditioner. The oilshould be changed every 100 hours of operation orbi-annually (more often if operated under heavy loads).The Oil Bath holds 3 qts (2.84 L) of SAE #80W90EPGear Lube. Check oil level as shown in Figure 13.

The Oil Bath should be checked occasionally for oildrips and dust accumulation around the Seals. Oil dripsor dust accumulation indicate that the Seals are leaking.Oil which is tan in color and foams excessively indicatesthat it has water present. To change the oil, observe thefollowing steps:

1. Remove the Top Right Cover.

2. Remove Lower Right Cover to allow oil to drain.

3. With a rag, wipe out the lower areas of the Frame.

4. Clean and apply silicone sealer to the LowerCover. Clean Cover mating surface of Frame andinstall Lower Cover.

5. Refill Oil Bath with 3 qts (2.84 L) of SAE#80W90EP Gear Lube.

6. Clean and apply silicone sealer to the top area ofLower Cover where Top Cover seats. Clean TopCover and mating surface of Frame and install TopCover.

Apply a good grade of foaming aerosol lubricant, suchas NAPA Chain and Cable Lubricant, to the Front andRear Telescoping PTO Drive Shields.

WARNINGDo NOT remove Hydraulic Tongue ControlCylinder with Conditioner Header off theground. Failure to heed can result in death orserious injury.

HYDRAULIC LIFT CYLINDERS(Fig. 23)The Disc Conditioner Lift System consists of a “master-slave” cylinder arrangement, as shown. With a “master-slave” setup, the hydraulic oil, from the rod end of themaster cylinder, goes into the base end of the slave


cylinder. Because of this arrangement, both cylinderswill extend equally, under any load.

With a “master-slave” arrangement, the cylinders canbecome un-phased such that the machine will raiseunevenly (left end higher or lower than the right end).Use the following steps to re-phase the lift cylinders:

1. Completely raise and lower the unit several times,keeping the tractor hydraulic lever engaged, untilNO cylinder movement is observed.

NOTE: The cylinders will move very slowly,while equalizing.

2. If the unit is still unequal, proceed to step 3 or 4,depending on the problem.

WARNINGBE SURE there is NO pressure in the lines,when loosening the fittings. Hydraulic fluid,under pressure, can penetrate the skin. Ifinjured by escaping fluid, see a doctor atonce. Injected fluid MUST BE surgicallyremoved by a doctor familiar with this type ofinjury or gangrene may result.

3. If the slave cylinder (right) will NOT raise fully,when the master cylinder (left) is fully raised,loosen the fitting into the slave cylinder (bleedpoint as shown). With the fitting loose, raise theunit, until oil appears at the fitting. Then,re-tighten the fitting and repeat step 1.

4. If the master cylinder (left) will NOT raise fully,when the slave cylinder (right) is fully raised,loosen the fitting that goes into the slave cylinder(bleed point as shown). With the fitting loose,remove approximately 1/2 cup (4 oz) of oil forevery one inch of cylinder length difference.Then, re-tighten the fitting and repeat step 1.

If the hydraulic cylinders become un-phased frequently,during use, it will be necessary to replace the piston sealsin the master cylinder. Only replace the slave piston sealif it is leaking externally.

NOTE: A leaking tractor valve may cause one orboth hydraulic cylinders to raise slowly whilecutting.

TELESCOPING DRIVES

NOTE: For safety reasons, service on theTelescoping PTO Drives should ONLY beperformed by (or under the direction of) anauthorized GEHL equipment dealer.

Over time, the Telescoping Drive Universal Joints maybecome worn and noisy and require service. Asnecessary, remove the Drive(s) from the DiscConditioner and take them to your dealer.


TIRES & WHEELSThe Tires should be inflated to different pressures.Inflate the right side to 36 PSIG (252 kPa) and the leftside to 18 PSIG (126 kPa). The Wheel lug nuts shouldbe torqued to 90 ft-lb. The Wheel Bearings should betorqued to 55 ft-lb, while oscillating the Wheel at least90°, then, the slotted nuts should be backed-off between1 and 2 cotter pin slots.

NOTE: Under hilly conditions, it is necessary toadd a 95% calcium chloride solution to the left tirefor additional stability.

Check the Conditioner tire pressures after every 50hours of operation. Tires should be inflated to 36 PSIG(252 kPa) on the right side and to 18 PSIG (126 kPa) onthe left side. Wheel Lug torque should be checked afterevery 50 hours of operation and tightened to 90 ft lb (124Nm) torque.

CAUTIONOur Company does NOT sell replacementTires. In addition, Tire mounting, repair andreplacements should ONLY be attempted by aqualified tire manufacturer’s representativeor by properly trained personnel following thetire manufacturer’s instruction. If you do NOThave such instructions, contact your tire deal-er or our Company.

WARNINGInflating or servicing tires can be dangerous.Whenever possible, trained personnel shouldbe called to service and/or mount tires. Inaddition, do NOT place your fingers on the tirebead or rim during inflation; serious injury oramputation could result. In any event, toavoid possible death or serious injury, followthe safety precautions below:

• BE SURE the Rim is clean and free ofrust.

• Lubricate both the tire beads and rimflanges with a soap solution. Do NOT useoil or grease.

• Use a clip-on tire chuck with a remotehose and gauge which allows you tostand clear of the tire while inflating it.

• NEVER inflate beyond 35 PSI (240 kPa) toseat the beads. If the beads have NOTseated by the time the pressure reaches35 PSI, deflate the assembly, repositionthe tire on the rim, relubricate both partsand re-inflate it. Inflation pressure be-yond 35 PSI with unseated beads maybreak the bead or rim with explosiveforce sufficient to cause death or seriousinjury.

• After seating the beads, adjust the infla-tion pressure to the recommended oper-ating pressure listed.

• Do NOT weld, braze, or otherwise attemptto repair and use a damaged rim.

CHAPTER 14SET-UP & ASSEMBLY

HANDLING CRATED UNIT

The DC2340 and DC2360 Disc Conditioners areshipped from the factory in three separate shippingbundles consisting of the Main Frame package, theDrawbar package and the Completing Parts box. TheMain Frame is packaged at the factory in such a way thatthe front of the Header is next to the ground andWindrow-forming Chamber is pointed upwards.Discardable shipping crate is secured to the front of theHeader for additional stability during warehousing.

Depending on facilities, the unit can either be handledwith a forklift truck (capable of carrying at least 4000 lb)or, with a 2 ton overhead hoist, using lifting points oneach Spring Tower or on each Axle. In either case,handle the machine carefully, so as NOT to damage it.If a forklift is going to be used, BE SURE to spread theforks as far apart as possible and insert them under theshipping frame.

WARNINGBEFORE attempting to lift the unit witha forklift, securely attach chains fromthe shipping mounts to the forklift, onboth ends of the unit, to prevent theunit from swinging away, when the unitis picked up. Also, BE SURE that nobodyis close to the unit while unit is beingtransported in the shipping position.

UNCRATING UNIT (Fig. 34)

After the machine is placed on a solid level surface in itsuncrating location, use the following steps and thedrawing provided to properly uncrate it:

1. Remove all items that are banded to the unit.

2. Securely attach a long heavy chain to the WheelAxles. Then, securely attach the chain, with aspreader bar, to the forklift carriage or hoist.MAKE SURE to leave the Shipping Wires fromthe Axles to the Spring Towers installed whileletting the unit down from the shipping position.

NOTE: The chain(s) being used MUST beequipped with safety lock clevises to assure thatthe chain does NOT disconnect as the Conditioneris being lowered. A spreader bar, capable of liftingat least 4000 lb (1820 kg) and that is at least aswide as the distance between the Disc Conditionerlegs, MUST be used. The spreader bar used MUSThave a reach of 95″ (242 cm) for the DC2340 and110″ (280 cm) for the DC2360. The bar will keepthe chain apart and prevent the chain from crushingthe sides of the Windrow Forming Chamber. Inaddition, BE SURE that the chain is long enoughso that the Forming Chamber will clear thespreader bar as unit is being pivoted down.

DANGERDo NOT allow anyone near the unit, whileit is being lowered. Also, BE SURE that thechains are long enough and strongenough to do the job.

3. Keeping tension on the chain at all times, raise theforklift carriage to a point approximately 2 feethigher than the end of the Windrow FormingChamber. Then, as shown in the drawing provided(Figure 34), slowly pull and lift on the MowerConditioner to rotate it around and rest it on thefloor.
