INTRODUCTION

Your new 973/974 Header is specially designed as a “straight cut” header, to be attached to your combine using a model 873 Adapter. These headers are equipped to work well in all straight cut conditions, whether cutting on or above the ground. When weather is not a critical factor, straight cutting eliminates the windrowing operation.

NOTE: This manual contains information on the Header only. It must be used in conjunction with your Adapter and Combine Operator's Manual.

CAREFULLY READ ALL MANUALS TO BECOME FAMILIAR WITH RECOMMENDED PROCEDURES BEFORE ATTEMPTING TO UNLOAD, ASSEMBLE OR USE THE MACHINE.

Use this manual as your first source of information about the header. If you follow the instructions given in this manual your Header will work well for many years.

This manual contains information on "Safety", "Operation" and "Maintenance/Service". In addition, "Unloading and Assembly" instruction is given towards the back of this book.

Use the Table of Contents and the Index to guide you to specific areas. Study the Table of Contents to familiarise yourself with how the material is organised.

Keep this manual handy for frequent reference and to pass on to new operators or owners. Call your dealer if you need assistance, information or additional copies of the manual.

NOTE: Right hand (R/H) and Left-hand (L/H) designations are determined from the operator’s position, facing forward.

NOTE: A storage case for this manual is located under the left endsheet.

GENERAL SAFETY

The following are general farm safety precautions that should be part of your operating procedure for all types of machinery.

1. Protect yourself.

When assembling, operating and servicing machinery wear all the protective clothing and personal safety devices that COULD be necessary for the job at hand. Don't take chances.

You may need:

• a hard hat.

• protective shoes with slip resistant soles.

• protective glasses or goggles.

• heavy gloves.

• wet weather gear.

• respirator or filter mask.

• hearing protection. Be aware that prolonged

exposure to loud noise can cause impairment or loss of hearing. Wearing a suitable hearing protective device such as earmuffs (A) or earplugs (B) protects against objectionable or loud noises.

2. Provide a first-aid kit for use in case of emergencies.

3. Keep a fire extinguisher on the machine. Be sure the extinguisher is properly maintained and be familiar with its proper use.

4. Keep young children away from machinery at all times.

5. Be aware that accidents often happen when

the operator is tired or in a hurry to get finished. Take the time to consider the safest way. Never ignore warning signs of fatigue.

GENERAL SAFETY

6. Wear close-fitting clothing and cover long hair. Never wear dangling items such as scarves or bracelets.

7. Keep hands, feet, clothing and hair away from moving parts. Never attempt to clear obstructions or objects from a machine while the engine is running.

8. Keep all shields in place. Never alter or remove safety equipment. Make sure driveline guards can rotate independently of the shaft and can telescope freely.

9. Use only service and repair parts made or approved by the equipment manufacturer. Substituted parts may not meet strength, design, or safety requirements.

10. Do not modify the machine. Unauthorised modifications may impair the function and/or safety and affect machine life.

11. Stop engine and remove key from ignition before leaving operator's seat for any reason. A child or even a pet could engage an idling machine.

12. Keep the area used for servicing machinery clean and dry. Wet or oily floors are slippery. Wet spots can be dangerous when working with electrical equipment. Be sure all electrical outlets and tools are properly grounded.

13. Use adequate light for the job at hand.

14. Keep machinery clean. Straw and chaff on a hot engine are a fire hazard. Do not allow oil or grease to accumulate on service platforms, ladders or controls. Clean machines before storage.

15. Never use gasoline, naphtha or any volatile material for cleaning purposes. These materials may be toxic and/or flammable.

16. When storing machinery, cover sharp or extending components to prevent injury from accidental contact.

OPERATION

OPERATING VARIABLES

Satisfactory function of the header (and hay conditioner) in all situations requires making proper adjustments to suit various crops and conditions.

Correct operation reduces crop loss and allows cutting of more acres. As well, proper adjustments and timely maintenance will increase the length of service you receive from the machine.

The variables listed here and detailed on the following pages will affect the performance of the header and conditioner. You will quickly become adept at adjusting the machine to give you the desired results.

CUTTING HEIGHT

Desired cutting height will vary depending on type of crop and other factors.

Gauge Wheels / Transport Option

For headers with gauge wheels or transport option choose appropriate pin position for stubble height.

OPERATION

CUTTING HEIGHT (continued)

Skid Shoes

In crops and conditions where it is desirable to cut close to the ground, use skid shoes to vary cutting height. The operator can then lower the header to the ground, allowing the shoes to provide a consistent cutting height.

NOTE: Lowering the skid shoes raises the cutting height. This may be desirable in stony conditions, to reduce damage to cutting components. Other benefits include reduced plugging due to mud or dirt build-up and longer stubble for faster drying.

Outer skid shoes have four settings to provide a coarse adjustment for cutting height. Height can then be fine-tuned with header angle adjustment.

Tip: With header angle in the steeper part of the range (center link more extended), lower skid shoes until cutterbar and shoes contact the ground at the same time when lowering header. Then when operating, flattening the header angle (retracting center link) will raise the cutterbar (guards) while the skid shoes stay on the ground. This may be useful to clear trash build-up on cutterbar, or in rocky conditions. See "Header Angle" in this section.

To change end skid shoe position:

1. Loosen front bolt, securing skid shoes at (A).

2. Remove hardware at shoe (B), both ends of header.

3. Position shoe at the desired setting, and install hardware (B).

4. Retighten front bolt.

NOTE: When end skid shoes are not required, shoes and bolt-on brackets (C) may be removed.

To change inner skid shoe position:

1. Remove hardware at (D) both sides of header leg.

2. Position shoe at desired height and install hardware (D).

3. Tighten hardware (D).

NOTE: Adjust all shoes to the same height to provide an even cutting height.

DANGER: To avoid bodily injury or death from unexpected start-up or fall of raised header; stop engine, remove key and engage header lift cylinder stops before going under header to adjust skid shoes (or for any reason).

OPERATION

GROUND SPEED

• Ground speed should be such that the sickle can cut crop smoothly and cleanly, while giving the desired

delivery of material to the opening. Excessive ground speed results in "ragged" cutting.

• In tough-to-cut crops like flax, reduce ground speed to reduce loads on cutting components and drives.

• Higher ground speeds require heavier float settings to prevent excessive bouncing. This will result in

increased cutting component damage.

• As ground speed is increased, draper and reel speed should be increased to handle the extra material.

The chart below indicates the relationship between ground speed and area cut for the four header sizes. Example shown would be approximately 15-½ acres (6 hectares).

Form # 147083

Issue 01/07

OPERATION

HEADER FLOTATION

IMPORTANT: To avoid frequent breakage of sickle components, scooping soil, or soil build-up at cutterbar in

wet conditions, header float should be set as light as possible without causing excessive bouncing.

Under normal conditions, when cutting above the ground, adjust float spring tension so 50 - 70 lbs. force (225 315 N) is required to lift divider at either end. Cutting on the ground requires lighter float, approximately 30 lbs. (135 N) at each divider point.

Setting float on headers with gauge wheels

Headers with gauge wheels use the springs in the gauge wheel package to assist in header floatation. As such, the float adjustment for these headers must be set to take advantage of the extra flotation. Proceed as follows:

1. Set gauge wheels to medium stubble height

position (E).

2. Set center link to approximately 21-1/2 in. (545

mm) pin to pin.

3. Adjust adapter float spring drawbolts such that

gauge wheel arm (F) contacts pin (E) when the header is lowered. If header floats away from the pin, reduce float. If arm (F) contacts pin but float is heavy, increase float.

For 973 Headers, see "Header Flotation" in Combine Adapter Operator's Manual for adjustment details.

FLOTATION ADJUSTMENT – 974 FLEX HEADERS

Initial setting of the wing float and adapter spring float is done at machine Set-Up. See “Assembly” section at back of this book. The following covers field adjustments that may be required from time to time.

Cutting on the Ground

For cutting on the ground, best operation will occur with minimum extra weight on the header. Consider removing gauge wheels or transport attachment, if equipped. If weight is added or removed from the header, both wing float and adapter spring float may require readjustment.

Operating tips:

1. Set top link between adapter and header to mid-

range position (19-1/4”) (490 mm).

2. Ensure adapter float lockout is disengaged.

Adjust adapter float springs as described in Combine Adapter Operator’s Manual so that gap at (A) between float arm and down stop is 1/2” (13 mm) when cutterbar is 6” (150 mm) above ground. Notch (B) is provided as an alignment mark for this setting. This will result in about 2” (50 mm) gap under normal “ground hugging” conditions and float optimizer function. Header

can flex to “full frown” only when gap at (A) is around 2”.

3. Disengage wing float lock pins (Position (B), two

per side) to allow wings to float.

4. Adjust float optimizer while watching float indicator

to set desired cutterbar down force (flotation).

5. Adjust header angle to achieve desired stubble

height. NOTE: Use steps 4 and 5 to fine tune the header to achieve the shortest stubble height without pushing dirt

6. In rocky fields, adjust skid shoes down. This raises

guards when operating at the flattest header angle to minimize scooping rocks.

7. If cutterbar begins to push dirt during operation,

adjust header height (with optimizer or feeder house height control) to minimize pushing.

8. Header angle and reel fore-aft position can be

changed without significantly effecting header flotation.

Adjust Wing Downforce To Correct Uneven Float:

1. If stubble at dividers is longer than at center, or if

cutterbar pushes dirt in the center section of the header, adjust to transfer weight from the center section to the wings as follows:

• Loosen bell crank clamp bolt (C), located inside bell crank housing.

• Loosen nut (D) and turn nut (E) to raise bell crank bolt (F).

• Tighten clamp bolt (C).

• NOTE: Make small adjustments in position of tee

bolt (one or two turns) followed by field test. If the tee bolt is adjusted more than 10 turns in total, perform the entire “Wing Float Set-Up” procedure detailed on page 87.

2. If stubble at center of header is longer than at dividers, or if cutterbar pushes dirt near the ends of the header, proceed as in Step 1, but lower the tee bolt to transfer weight from the wings to the center section.

3. When properly adjusted, the wing float indicators (G) will be moving continuously, indicating header wings are flexing between “smile” and “frown”. If not, readjust as required per steps 1 & 2.

NOTE: Functions of inner and outer wing float lock pins – Each wing of the Flex Header

has an inner and outer float lock-out pin as shown in top photo above. These pins can be engaged (as at (A) above) or disengaged (as at (B) above) with the following results:

• Both pins engaged – Wing float is fully locked out.

• Inner pin engaged, Outer pin disengaged – Wing can smile, not frown.

• Outer pin engaged, Inner pin disengaged – Wing can frown, not smile

• Both pins disengaged – Wing is free to flex to smile and frown positions.

Cutting above the Ground

When cutting above ground, for example in cereal grains, note the following:

1. The header can be operated with the wing float lock pins engaged or disengaged.

• Engaging the wing float lock pins will keep cutterbar straight at all times.

• Operating with wing float lock disengaged will reduce the force on guards in rocky conditions, and

allows the wings to flex when the header contacts the ground.

2. Gauge wheels can be used to stabilize the header.

Form # 147083

Issue 01/07

OPERATION

HEADER ANGLE

The header angle can be varied within these ranges: Measured at Guards: 3.5° to 9.1° (cutterbar on ground). Measured at Drapers: 14° to 19.6° (cutterbar on ground). Achievable angles may vary depending on combine face plate angle.

IMPORTANT: The flattest header angles are recommended for normal conditions. A flatter header angle reduces sickle section breakage and reduces soil scooping or build-up at the cutterbar in wet conditions. Use a steeper angle to cut very close to the ground, or in down crop for better lifting action.

Header angle is varied by adjusting the length of the top link (mechanical or hydraulic) between adapter and header. See "Header Angle" in Combine Adapter Operator's Manual for adjustment details.

DRAPER SPEED

Draper speed affects the orientation of stalks in the delivered crop. See Combine Adapter Operator's Manual for adjustment details.

Adjust delivery opening width:

Decks can be slid inwards to adjust opening size without cutting or extending the drapers All headers are supplied with a long draper which may be cut to provide a wider opening. By cutting both drapers, opening can be increased by 19” (480 mm). If reducing the opening size after it has been enlarged, a short section of draper (available from your dealer) can be added to increase draper length.

NOTE: To avoid damage to draper and/or draper tension mechanism, do not use drapers that are different in length from those specified.

For adjusting opening size without cutting drapers, go to step 8:

To cut or extend draper:

1. Release draper tension by turning bolt (D) counterclockwise until bolt begins to turn out of backsheet.

2. Remove screws from draper connector slat.

3. Use the following chart to determine which opening size and row of holes are required for the desired application.

NOTE: Recommended starting point is with decks shifted in, column (Y) for rows I and III. For row II start at 45.4” (1155 mm) for specialty crops and 42.1” (1070 mm) or less for cereal crops.

4. Verify that the idler roller assembly is

bolted into the deck in the correct position for the selected opening size. See "Idler Roller Positioning" in Maintenance/ Service section.

5. If increasing delivery opening width:

Cut excessive flap off of draper, leaving 3/8" (10 mm) extending above the connector. Trim the new ends at the front and rear corners as shown on previous page. This allows draper to fit properly under draper seals to prevent tearing of edges. Use the cut-offs as a guide for trimming. Keep the cut-offs for use as a splice.

6. NOTE: Place connector tube so holes closest to

end of tube are at cutterbar. Connect draper with screw heads facing center opening.

7. Apply draper tension as follows:

• Check that draper V-guide is properly engaged in grooves at rear of both rollers.

• Tighten bolt (D) until white indicator bar is partially hidden behind the roller support arm at (F). IMPORTANT: To avoid premature failure of draper, draper rolls and/or tightener components, do not operate with tension set so that white bar is fully hidden.

8. Slide decks to desired opening width:

• Loosen clamp (E) at top of deck. (For 36’ & 39’ Headers, there are two clamps.)

• Slide deck to achieve desired header opening (see chart on previous page). The recommended starting position is with decks shifted in.

• Tighten nut at clamp (E).

END DELIVERY: WINDROWING WITH THE COMBINE

The left or right deck of the header can be moved to close off the center opening and deliver crop to either end of the header. This provides the capability of windrowing with the combine.

NOTE: For 36’ & 39’ Headers, a kit is available to split the R/H deck to deliver crop next to the combine tire. See Options and Attachments section.

To shift deck:

1. Install bar (C) onto lugs across center opening at cutterbar. This prevents draper damage when end delivering. (Bar is stored on right deck backsheet.) NOTE: Insert the flange nuts into slots in cutterbar lugs (engage from underside.)

2. Reverse draper travel on the deck being moved by disconnecting hydraulic hoses at draper motor (A) and install in opposite ports.

3. For Model 873 Adapters, re-route hydraulic hoses from pump to stop hydraulic flow to the feed draper and drum. See “Windrowing with the Combine” in the 873 Adapter Op. Manual

4. Lower the header to the ground and continue until adapter lowers to clear deck shift lug.

5. Lengthen center link between header and adapter to steepest header angle to clear hose clamps on header back sheet

6. Loosen nut at clamp (B) and slide deck across center opening until there is approximately 2 inches (50 mm) clearance between the rollers of the two decks. IMPORTANT: This clearance is required to prevent contact between draper connectors or slats as they pass between decks. NOTE: If there is interference between deck backsheet and combine adapter retracting tine drum, move drum back to provide clearance (if clearance to combine feed drum allows). See “Drum Fore-Aft Adjustment” in 873 Adapter Operator’s Manual. NOTE: For 974 Headers, disassembly of inboard front deck support will be necessary to allow deck to slide past cutterbar hinge.

7. Tighten nut at clamp (B).

8. Readjust center link to achieve desired header operating angle.

9. With header and combine feed chain drum floated up, check clearances: There should be 1 to 2 inches (25 to 50 mm) clearance between adapter drum and combine feed chain drum, while still providing adequate clearance to header backsheet. If repositioning adapter drum does not provide enough clearance both fore and aft, remove one row of tines from drum.

REEL SPEED

• Reel speed affects feeding of crop into the sickle and onto the drapers, as well as the smoothness and evenness of the delivered crop. Operating the reel too fast or too slow relative to ground speed will cause bunching.

• In standing crop, reel speed should be just faster than ground speed, sweeping crop across the sickle.

• The more "down" the crop, the faster the reel speed should be in relation to ground speed. This can be achieved by increasing reel speed, decreasing ground speed, or both.

• Excessive shattering of grain heads or crop loss over the header back tube may be indications that reel speed is too fast. Excessive reel speed causes undue wear of reel components and unnecessary load on reel drive, resulting in uneven reel motion.

• A high torque reel drive sprocket (11 teeth) (A) is standard on the Header. The high torque is required for many conditions such as rice and other heavy crops. An optional high speed reel drive sprocket (17 teeth) is recommended when operating at speeds over 6 mph (10 km/h). Two links of chain need to be added when converting from high torque to high speed. See your Dealer Parts Department to order the optional sprocket and chain.

REEL HEIGHT

• Depending on crop height, adjust reel height to carry material through the sickle onto the drapers.

• Down crop will require a lower reel height to wipe crop off the sickle.

• Bushy crop may require raising the reel to prevent unevenness in delivery.

• Indications that reel may be too low are crop loss over the header back tube, or disturbance of crop on the

drapers by the reel fingers.

Issue 01/07

OPERATION

REEL POSITION

IMPORTANT: When difficulty is encountered picking up down crop, start by adjusting header angle to a

steeper position. This tilts the entire reel/sickle/draper combination and is often all that is required. See "Header Angle" in Combine Adapter Operator's Manual for adjustment details. Adjust reel position only if header angle adjustments are not satisfactory.

Reel fore-aft position can be adjusted mechanically (973) or hydraulically (974) to suit various crop conditions. A gauge decal is provided on the left reel support arm for identifying a preferred position. The back edge of the reel end shield is the gauge indicator (A). For units with hydraulic header tilt as well as hydraulic reel fore-aft, use the selector switch in the cab to choose the desired function.

• For straight standing crop, center the reel over the cutterbar (4 or 5 on gauge).

• For crops that are down, tangled, or leaning, it may be required to move reel ahead of cutterbar (to a higher number on the gauge).

After adjusting reel fore-aft position, check reel clearance to cutterbar. Minimum finger to

REEL FORE AFT POSITION INDICATOR

guard/cutterbar clearance is as follows: For 973 Headers: 5/8 inch (15 mm). For 30’ 974 Headers: 1-3/4” (45mm) at each end and 2-1/4” (58mm) at center. For 36’ 974 Headers: 1-3/4” (45mm) at left end, 1” (25mm) at right end and 2-3/8” (60mm) at center. NOTE: Reel clearance to cutterbar is factory set as above. Adjustment should not normally be required. If required, refer to Maintenance/Service section for adjustment procedure.

To adjust reel fore-aft position (mechanical):

1. Lower reel so support arms are horizontal.

2. Remove bolt (A) at each support arm.

3. Using a 15/16” wrench on sprocket inside

reel arm, slide reel to the desired position. If reel binds on arms from misalignment, move in smaller increments (two holes at a time).

4. Install and tighten bolt (A). Be sure the

same hole is used at each arm.

5. Check reel clearance to cutterbar. See

measurements above.

TRANSPORTING THE HEADER ON COMBINE

WARNING: Do not drive combine with header attached on a road or highway at night, or in conditions which reduce visibility, such as fog or rain. The width of the header may not be apparent under these conditions.

CAUTION:

1. Check local laws for width regulations and lighting or marking requirements before transporting on roads.

2. Follow all recommended procedures in your Combine Operator's Manual for transporting, towing etc.

3. Disengage header drive clutch when travelling to and from the field.

4. Before driving combine on a roadway, be sure flashing amber lamps, red tail lamps and head lamps are clean and working properly. Pivot amber lamps for best visibility by approaching traffic. Always use these lamps on roads to provide adequate warning to other vehicles.

5. Do not use field lamps on roads, they may confuse other drivers.

6. Before driving on a roadway, clean slow moving vehicle emblem and reflectors. Adjust rear view mirror and clean windows.

7. Lower the reel fully and raise header unless transporting in hills. (See point #8.) Maintain adequate visibility and be alert for roadside obstructions, oncoming traffic and bridges.

8. When travelling down hill, reduce speed and keep header at a minimum height. This provides maximum stability if forward motion is stopped for any reason. Raise header completely at bottom of grade to avoid contacting ground.

9. Travel speed should be such that complete control and machine stability are maintained at all times.

10. Engage adapter spring float lockout and wing float lockout pins (974 Headers) to reduce bouncing.

NOTE: If transporting the header in field position on a flat bed trailer, take care when positioning

tie down straps to avoid damage to safety decals and reflectors on main tube.

OPERATION

STORAGE PROCEDURE

Do the following at the end of each operating season

1. Clean the header thoroughly.

CAUTION: Never use gasoline, naphtha or any volatile material for cleaning purposes. These materials may be toxic and/or flammable.

2. Cover cutterbar and sickle guards to prevent injury from accidental contact.

Also:

3. Store machine in a dry protected place if possible. If machine is stored outside, cover with a waterproof canvas or other protective material.

4. If machine is stored outside, remove drapers and store in a dark, dry place.

NOTE: If drapers are not removed, store header with cutterbar lowered so water/snow will not accumulate

on drapers. This accumulation of weight puts excessive stress on drapers and header.

5. Lower header onto blocks to keep cutterbar off the ground.

6. Lower reel completely. If stored outside, tie reel to frame to prevent rotation caused by wind.

7. Repaint all worn or chipped painted surfaces to prevent rust.

8. Lubricate the machine thoroughly, leaving excess grease on fittings to keep moisture out of bearings. Oil cutterbar and apply grease to exposed threads and sliding surfaces of components.

9. Check for worn or broken components and repair or order replacements from your dealer. Attention to these items right away will save time and effort at beginning of next season.

10. Replace or tighten any missing or loose hardware. See Specifications section for torque charts.

If more than one person is servicing the machine at the same time, be aware that rotating the driveline by hand (for example to access a lube fitting) will cause other drive components (belts, pulleys and sickle) to move. Stay clear of driven components at all times.

Be prepared if an accident should occur. Know where the first aid kit and fire extinguisher are located and how to use them.

Keep the service area clean and dry. Wet or oily floors are slippery. Wet spots can be dangerous when working with electrical equipment. Be sure all electrical outlets and tools are properly grounded.

Use adequate light for the job at hand.

Replace all shields removed or opened for service.

Use only service and repair parts made or approved by the equipment manufacturer. Substituted parts may not meet strength, design or safety requirements.

Keep the header clean. Never use gasoline, naphtha or any volatile material for cleaning purposes. These materials may be toxic and/or flammable.

RECOMMENDED LUBRICANTS

GREASE

Use an SAE Multi-Purpose High Temperature Grease with Extreme Pressure (EP2) Performance and containing a maximum of 1% moly (molybdenum disulphide).

For driveline slip-joints only, increased moly content (up to 10%) is recommended. IMPORTANT: Do not use this higher moly content grease on bearings, as it may cause excessive wear in high speed applications.

WOBBLE BOX LUBRICANT In sickle drive wobble box, use SAE 85W-140 gear lubricant. (API Service Classification GL-5)

Capacity: 2.2 litres (2.3 U.S. quarts)

STORING AND HANDLING LUBRICANTS

Your machine can operate at top efficiency only if clean lubricants are used. Contaminant in lubricants is the most likely cause of bearing and hydraulic system failure. Use clean containers to handle all lubricants. Store lubricants in an area protected from dust, moisture and other contaminants. Keep hydraulic couplers and connectors clean.

SEALED BEARING INSTALLATION

1. Clean shaft and coat with rust preventative.

2. Install flangette, bearing, flangette and lock collar.

The locking cam is only on one side of the bearing.

3. Install and tighten the flangette bolts.

4. When the shaft is located correctly, lock the lock

collar with a punch. The collar should be locked in the same direction the shaft rotates. Tighten the setscrew in the collar.

5. Loosen the flangette bolts on the mating bearing

one turn and re-tighten. This will allow the bearing to line up.

MAINTENANCE/SERVICE

DRAPERS (continued)

Draper Tracking Adjustment:

spring-loaded roller is located at the same end of the deck as the draper tensioner, and is self-aligning. Adjustments are not required to this roller. The fixed roller is aligned by re-positioning hardware in the slotted holes in the rear support arm. NOTE: For combine headers, the idler roller is always the fixed roller and the drive roller is always the springloaded roller.

To ensure square alignment for proper draper tracking, measure dimensions (A) and (B) from roller to channel at front and rear as shown. Align roller by loosening two bolts in rear support (C) and adjusting in slots until dimensions (A) and (B) are: 21’ & 25’ Headers – equal. 30’, 36’ & 39’ Headers – Dimension (B) 3 mm (1/8”) less than Dimension (A).

If drapers still do not track properly with the settings above, it may be necessary to bias the fixed roller alignment to correct the problem: NOTE: When adjusting the fixed roller, move in 2 to 3 mm increments. Before loosening hardware, scribe a mark on the rear arm and the backsheet to measure the amount the roller moves.

• If the draper is tracking back (towards backsheet) at the end of the deck with the fixed roller, increase dimension (B).

• If the draper is tracking ahead (towards cutterbar) at the end of the deck with the fixed roller, decrease dimension (B).

• If the draper is tracking back (towards backsheet) at the end of the deck with the spring-loaded roller, decrease dimension (B).

• If the draper is tracking ahead (towards cutterbar) at the end of the deck with the spring-loaded roller, increase dimension (B).

NOTE: If the fixed roller is positioned too far off of square in an attempt to correct a tracking problem on the spring-loaded roller, tracking at the fixed roller will be adversely affected. In this case, check the draper for squareness and re-punch draper connecting holes if necessary.

Idler Roller Maintenance

NOTE: When tightening nuts at ends of idler roller,

torque to 30 - 45 ft.lbs. (40 - 60 N·m). Overtightening may cause thread to fail.

When reassembling idler roller, install both seals (K) with flat face (with writing) out and install bearing (L) with shielded side facing out.

6. Clean inside of roller tube and stub shaft (D). Check tube and stub shaft for wear or damage. Replace if necessary.

7. Place retaining ring (E) onto stub shaft (D) and hang it loosely over stub shaft mounting face. IMPORTANT: Retaining ring must be in position on stub shaft before installing bearing into tube.

8. Sub-assemble seal (F), bearing (G) and washer (H) onto stub shaft and secure with lockwasher (J) and bolt (C). IMPORTANT: Install seal (F) with flat face (with writing) out, and install bearing (G) with shielded side out.

9. Remove grease fitting (K) and press on end of stub shaft to install bearing sub-assembly into roller tube. Press in until retaining ring (E) can be installed in groove inside tube. To prevent damage to bearing, do not press the assembly deeper than necessary.

10. Reinstall fitting (K) into stub shaft and grease until grease appears past seal.

11. Reassemble drive roller into deck, re-couple and tighten draper.

NOTE: At drive roller to motor connection, there is a short "through-bore" setscrew (L) on top of setscrew (M). When removing, be sure to engage Allan wrench only far enough to remove setscrew (L) first, then setscrew (M).

Deck Height

To prevent material from entering drapers and cutterbar, maintain deck height so that draper runs just below cutterbar with maximum 1/32” (1 mm) gap, or with draper deflected down slightly [up to 1/16” (1.5 mm)] to create a seal.

Adjust as follows:

1. Loosen tension on drapers.

2. Lift draper up at front edge and loosen two nuts on deck support (N), two or three per deck, depending on header size.

3. Tap deck up or down relative to supports to achieve setting recommended above.

Reel Clearance To Cutterbar

Minimum finger to guard/cutterbar clearance is as follows:

• For 973 Headers: 5/8 inch (15 mm) at both ends of cutterbar.

• For 30’ 974 Headers: 1-3/4” (45mm) at each end and 2-1/4” (58mm) at center.

• For 36’ 974 Headers: 1-3/4” (45mm) at left end, 1” (25mm) at right end and 2-3/8” (60mm) at center.

NOTE: Reel clearance to cutterbar is factory set as above. Adjustment should not normally be required.

NOTE: For 974 Flex Header, place cutterbar in full frown position to take measurements: Lower cutterbar onto two 6” (150 mm) blocks placed just inboard of wing flex points. Minimum clearance will occur at the hinge areas.

Check all possible points of contact between points (X). Depending on reel fore-aft position, minimum clearance can occur at guard tine, hold-down or cutterbar.

Check reel clearance whenever the reel fore-aft position or finger pitch is changed.

When operating reel with an aggressive finger pitch, be sure that fingers will not contact sickle when flexed back by crop, as at (R).

To adjust reel clearance to cutterbar:

1. Raise header and engage header lift cylinder stops. Lower header onto stops. Lower the reel fully.

2. Loosen and back off nut (A).

3. Turn nut (B) clockwise to increase clearance to cutterbar, or counter-clockwise to decrease.

4. Tighten nut (A) against nut (B) to secure the position.

5. Repeat at opposite side.

Reel "Frown" Adjustment

The reel has been factory adjusted to give more clearance at the center of the cutterbar than at the ends. This compensates for flexing of the reel and header over rough ground. For 974 Flex Header, use the adjustment to provide adequate reel clearance at dividers

The "frown" is adjusted by repositioning the hardware connecting reel finger tube arms to reel discs. If reel is disassembled for service, adjust positioning of hardware in holes (C) to maintain the proper profile. NOTE: Take these measurements with the reel centered over the cutterbar (see "Reel Position" in Operation section). This will provide adequate clearance at all reel fore-aft positions.

NOTE: This adjustment can also be used to compensate for reel tube and cutterbar tolerances.

When adjusting, start with the reel arm set closest to the center of the header, and work your way out to the ends, allowing the reel arms to find a natural curve, and positioning the hardware appropriately.

NOTE: In some locations, top and bottom bolts in the same reel arm may not be in the same hole position. (See photo.)

Tire Inflation

Check tire pressure daily kPa) for gauge wheels with Transport option. Maintain 60 psi (414 kPa) for non-transport gauge wheels.

increase air pressure beyond 35 psi (241 kPa) to seat the bead on the rim. Replace the tire if it has a defect. Replace a wheel rim which has cracks, wear or severe rust. Never weld a wheel rim. Make sure all the air is removed from a tire before removing the tire from a rim. Never use force on an inflated or partially inflated tire. Make sure the tire is correctly seated before inflating to operating pressure.

Do not remove, install or make repairs to a tire on a rim unless you have the proper equipment and experience to perform the job. Take the tire and rim to a qualified tire repair shop. If the tire is not in correct position on the rim, or is too full of air, the tire bead can loosen on one side, causing air to leak at high speed and with great force. An air leak of this nature can thrust the tire in any direction, endangering anyone in the area.

(A) - Use a safety cage if available.

(B) - Do not stand over tire. Use a clip-on chuck

and extension hose.

MAINTENANCE/SERVICE

MAINTENANCE SCHEDULE

The following maintenance schedule is a listing of periodic maintenance procedures, organized by service intervals. For detailed instruction, see the specific headings in Maintenance/Service section. Use "Recommended Lubricants" as specified under that heading.

SERVICE INTERVALS The recommended service intervals are in hours of operation. Use the hour meter in the combine cab to indicate when the next service interval has been reached.

IMPORTANT: Recommended intervals are for average conditions. Service header more often if operated under adverse conditions (severe dust, extra heavy loads, etc.) Regular maintenance is the best insurance against early wear and untimely breakdowns. Following this schedule will increase machine life. Where a service interval is given in more than one time frame, e.g. "100 Hours or Annually", service the header at whichever interval is reached first.

CAUTION: Carefully follow safety messages given under "Service Procedures".

Cutterbar has filled up with trash in excessively dirty conditions with draper to cutterbar gap properly adjusted.

Shifting of decks with

header raised up does not clean out cutterbar debris.

Cut at angle to ridges or crop rows to allow knife and guards to clean out better. When cutting in line with tracks or ridges the same guards and sections have to cut in dirt for the whole length of the field. Cutting at an angle shifts these ridges through all guards and prevents pushing dirt.

Cut at 90° to undulations, provided knife floats across without digging in.

Adjust front deck hooks to obtain proper clearance between cutterbar and draper. If cutterbar still fills up with dirt, raise header to max. up position at each end of field or as required and shift decks back and forth to help clean out cutterbar. Most dirt will fall out without manually having to clean drapers.

Raise header to max up position at each end of field or as required and shift decks back and forth to help clean out cutterbar. Most dirt will fall out without manually having to clean drapers.

3. Connect draper with screw heads (S) facing

center opening. NOTE: Place connector tube so holes closest to end of tube are at the cutterbar.

4. Ensure V-guide on underside of draper

engages grooves at rear of both rollers.

5. Check draper to cutterbar clearance. Maximum gap is 1 mm. If adjustment is required, see “Deck Height” on page 55.

6. Apply draper tension until white indicator bar is

partially hidden behind roller support arm. See "Draper Tension Adjustment" in Maintenance /Service section of Operator's Manual.

7. Position decks to dimension (X) (see chart on

previous page) for desired opening width. The recommended starting position is with decks shifted in. See "-Delivery Opening Width" in Operation section of Operator's Manual.

8. Align idler rollers for proper draper tracking. Align roller by loosening two bolts in rear support (C) and adjusting in slots until dimensions (A) and (B) are:

21’ & 25’ Headers – equal front and rear. 30’, 36’ & 39’ Headers – Dimension (B) 3 mm (1/8”) less than Dimension (A).

See page 54 for details.

9. Cut excessive flap off of draper, leaving 3/8" (10 mm) extending above the connector. Trim the new ends at the front corners as shown on page 82. This allows draper to fit properly under front draper seal to prevent tearing of front edge. Use the cut-offs as a guide for trimming. Keep the cut-offs for use as a splice.

BLEED HYDRAULIC SYSTEM

Header Lift Cylinders

Raise and lower header a few times to allow trapped air to pass back to the reservoir.

Reel Lift Cylinders

CAUTION: Take care during this procedure as air in the system can cause the reel to raise and lower erratically. Keep body and hands out from under reel and reel support arms.

1. Fully lower header and reel.

CAUTION: Bleed screw (A) may be forced from hole by hydraulic pressure. Do not loosen screw too quickly or too far.

2. SLOWLY loosen bleed screw (A) at top of slave reel lift cylinder.

NOTE: For 21’, 30’, 36’ & 39’ headers, slave

cylinder is at right end of header. For 25’ Header, slave cylinder is at left end.

3. Start engine and activate reel lift. Left-hand

cylinder will reach full extension first, then oil will pass to right hand cylinder.

4. Continue to activate reel lift until oil comes out

around bleed screw.

5. Tighten bleed screw.

Reel Fore-Aft Cylinders (if equipped):

To prevent damage to fore-aft components and/or reel, before moving reel with fore-aft kit:

1. Remove cylinder pins at rod ends and support cylinders to allow unobstructed movement of cylinder rods.

2. Activate hydraulics, extending and retracting cylinders several times to fill system with oil and ensure cylinders are in phase.

2. Install adapter in header. Leave the adapter spring float lockout engaged. See Adapter Operator’s Manual.

IMPORTANT: For units with gauge wheels, pin the gauge wheels up off the ground so their flotation effect does not interfere with the wing float setting.

3. Ensure wing float lock pins (2 per side) are in engaged position (A) as shown. Pins are spring loaded to the engaged position. If pins are disengaged:

• Rotate pin handles to release the roll pins

from the notch.

• Lower cutterbar onto two 6” (150 mm) blocks

at dividers until inner pins snap into engaged position.

• Remove blocks and place them just inboard

of cutterbar flex points

• Lower header onto blocks until outer pins

snap into place.

WING FLOAT LOCKOUT ENGAGED

4. Pick up header with combine and raise cutterbar approximately 6” (150 mm) off ground. (Remove blocks if they were required for Step 3.)

5. The smile/frown, fore-aft straightness and vertical alignment of the wing frames is controlled at the factory. Adjustment should not be required. Procedures for checking and adjustment are included in the Header Technical Manual.

6. Set top link to a mid-range header angle position (approximately 490 mm [19-1/4”] pin to pin).

7. Disengage adapter float spring lockout, both sides. Ensure gap at (C) is 1/2” (13 mm) with cutterbar 6” (150 mm) off ground. NOTE: Notch (D) is provided as an alignment
