OPERATION YOUR RESPONSIBILITIES AS AN OWNER/OPERATOR CAUTION: 1. It is your responsibility to read and understand this manual plus the Adapter and Combine Operator's Manual completely before operating the header. Contact your dealer if an instruction is not clear to you. 2. Follow all safety messages in the manuals and on safety signs on the machine. 3. Remember that YOU are the key to safety. Good safety practices protect you and the people around you. 4.
OPERATION BREAK-IN PERIOD 1. After attaching header to combine or windrower tractor for the first time, operate the machine with reel drapers and sickle running slowly for 5 minutes, watching and listening FROM THE OPERATOR'S SEAT for binding or interfering parts. CAUTION: Before investigating an unusual sound or attempting to correct a problem, shut off engine, engage parking brake and remove key. NOTE: Reel and side drapers will not operate until oil flow fills the lines. 2.
OPERATION PRE-STARTING CHECKS: ANNUAL PRE-STARTING CHECKS: DAILY Do the following at the start of each operating season. Do the following each day before start-up: CAUTION: CAUTION: 1. Clear the area of other persons, pets etc. Keep children away from machinery. Walk around the header to be sure no one is under, on or close to it. 1. Review the Operator's Manuals to refresh your memory on safety and operating recommendations. 2. Remove foreign objects from the machine and surrounding area. 2.
OPERATION OPERATE CORRECTLY CAUTION: 1. Follow all safety and operational instructions given in your Operator's Manuals. If you do not have a combine manual, get one from your dealer and read it thoroughly. 2. Never attempt to start the engine or operate the machine except from the operator's seat. 3. Check the operation of all controls in a safe clear area before starting work. 4. Do not allow riders on combine. DO NOT ALLOW RIDERS 5.
OPERATION HEADER CONTROLS CAUTION: Be sure all bystanders are clear of machine before starting engine or engaging any header drives. See your Combine Operator's Manual for identification of in-cab controls for: • Header Drive Clutch • Header Height • Ground Speed • Reel Speed • Reel Height • Reel Fore Aft / Header Tilt HEADER LIFT CYLINDER STOPS DANGER: To avoid bodily injury or death from fall of raised header, always engage cylinder stops before going under header for any reason.
OPERATION OPERATING VARIABLES OPERATING VARIABLES Satisfactory function of the header (and hay conditioner) in all situations requires making proper adjustments to suit various crops and conditions. HEADER 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 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.
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.
OPERATION DIVIDER ROD LENGTH Divider rods are removable and two lengths are provided as standard equipment. The longer rods (A) are suitable when crop requires running down, while the shorter pointed rods (B) are better in standing crops. See the chart below for recommended rod length for various crops.
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.
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.
OPERATION HEADER FLOTATION ADJUSTMENT – 974 FLEX HEADERS Cutting on the Ground (Operating Tips continued) 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.
OPERATION HEADER FLOTATION ADJUSTMENT – 974 FLEX HEADERS 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.
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.
OPERATION DELIVERY OPENING WIDTH 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.
OPERATION To adjust delivery opening width: (continued) H G STANDARD DEFLECTOR NARROW DEFLECTOR 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. X DELIVERY OPENING 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.
OPERATION 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. C To shift deck: 1. Install bar (C) onto lugs across center opening at cutterbar.
OPERATION END DELIVERY: WINDROWING WITH THE COMBINE (continued) 10. Adjust header flotation to compensate for the shift in weight. See "Header Flotation”. 11. NOTE: For 974 Headers, engage the wing float lock out pins to avoid interference at cutterbar hinge when end delivering. See page 23. 12. For rotary combines with narrow feeder opening, increase delivery opening width to be suitable for windrowing. See "Delivery Opening Width", beginning on page 26. 13.
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.
OPERATION REEL POSITION (continued) To adjust pick-up reel finger pitch: If adjusting the reel fore-aft position does not provide proper feeding, the finger pitch can be adjusted by repositioning bolt (B). Slot 1: least aggressive (standing crop) Slot 5: recommended starting position Slot 9: most aggressive (down, tangled crop) TIP: In bushy crop that sits high on drapers, try a more aggressive finger pitch to reduce carryover. The Trouble Shooting section includes other tips to improve performance. 1.
OPERATION UPPER CROSS AUGER (Optional) For tall or bulky crops, the optional upper cross auger will aid crop flow across the header and through the delivery opening. The vertical position of the upper cross auger is adjustable for best feeding of the crop. Extremely tall crops will require a higher setting. B To adjust vertical position: A 21’ & 25’ Headers • Loosen two bolts (A) both sides. • Adjust vertical position with drawbolt (B). • Exposed thread on bolts (B) should be the same both sides.
OPERATION SHUT DOWN PROCEDURE CAUTION: Before leaving operator's seat for any reason: 1. 2. 3. 4. 5. 6. 7. Park on level ground if possible. Lower the header and reel fully. Place all controls in NEUTRAL or PARK. Disengage header drive. Engage the park brake. Stop engine and remove key from ignition. Wait for all movement to stop. UNPLUGGING THE HEADER WARNING: Stop engine and remove key from ignition before removing plugged material from header. If the sickle plugs: 1. 2. 3. 4. 5.
OPERATION 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.
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.
MAINTENANCE/SERVICE SERVICE PROCEDURES CAUTION: To avoid personal injury, before servicing machine or opening drive covers: 1. Fully lower header and reel. If it is necessary to service in the raised position, first engage header lift cylinder stops and reel props. 2. Disengage header drive clutch. 3. Stop engine and remove key. 4. Engage park brake. 5. Wait for all moving parts to stop. Park on level surface when possible. Block wheels securely.

CUTTING EDIBLE BEANS: TROUBLESHOOTING SYMPTOM PROBLEM SOLUTION Header being carried off ground Lower header to ground and run on skid shoes and/or cutterbar Float set too light - rides on high spots and does not get back down soon enough Set float for: 100-150 lbs. - dry ground 50-100 lbs. - wet ground Float should be lighter for light soils and heavier for hard heavy soil areas Reel being operated too high Fully retract reel cylinders Operate reel at max.
CUTTING EDIBLE BEANS: TROUBLESHOOTING SYMPTOM PROBLEM SOLUTION Header stripping plantsComplete or partial plants left behind (continued) Reel too slow Adjust reel speed to be marginally faster than ground speed Tip: Look at perimeter of reel discs. they should appear to be being driven by the ground - If they look like they are skidding relative to ground, the reel is turning too slow - If they look like they are spinning excessively relative to ground, reel speed may be too fast and create shattering.
CUTTING EDIBLE BEANS: TROUBLESHOOTING SYMPTOM PROBLEM SOLUTION Header stripping plantsComplete or partial plants left behind (continued). Parts of vines get caught in regular guard tip while reel is trying to lift the vines above the knife and end up getting cut off. (This is more prevalent when cutting row-cropped beans that have been hilled due to cultivating. Install stub guard kit. Reel has a better chance of lifting the crop mat above the knife without any pods being cut by the knife.
CUTTING EDIBLE BEANS: TROUBLESHOOTING SYMPTOM PROBLEM SOLUTION Cutterbar pushing too much dirt in certain locations for length of field. Tire tracks or row crop ridges caused by seeding or spraying operations. 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.
