OPERATION BREAK-IN PERIOD 1. After attaching header to windrower tractor for the first time, operate the machine 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 park brake and remove key. 2. Check all belts after 5 hours operation for initial stretch. Tighten as necessary. (See Maintenance/Service section.
OPERATION PRE-STARTING CHECKS Do the following at the start of each operating season. CAUTION: 1. Review the Operator’s Manual to refresh your memory on safety and operating recommendations. 2. Review all safety signs and other decals on the machine and note hazard areas. 3. Be sure all shields and guards are properly installed and secured. Never alter or remove safety equipment. 4. Reaquaint yourself with the controls before beginning operation. Also: 5. Adjust tension on all belts and chains.
OPERATION PRE-STARTING CHECKS Do the following each day before start-up: 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. 2. Remove foreign objects from the machine and surrounding area. 3. Wear close fitting clothing and protective shoes with slip resistant soles. As well, carry with you any protective clothing and personal safety devices that COULD be necessary through the day.
OPERATION HEADER CONTROLS CAUTION: Be sure all bystanders are clear of machine before starting windrower or engaging any header drives. See the Windrower Tractor Operator's Manual for identification of in-cab controls for: • Header Drive Clutch • Header Height • Ground Speed • Reel Speed • Hydraulic Conditioner Roll Opener (Option) A 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 Satisfactory function of the header and hay conditioner in all situations requires making proper adjustments to suit various crops and conditions. AUGER HEADER 1. 2. 3. 4. 5. 6. 7. 8. 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 GROUND SPEED Ground speed of windrower should be such that sickle can cut crop smoothly and cleanly. See Windrower Tractor Operator's Manual for identification and instructions for use of ground speed control. The chart below indicates the relationship between ground speed and area cut for the three auger header sizes. Example shown: At a ground speed of 6 miles per hour (9.7 km/h) with a 14 ft. header*, the area cut per hour would be 10-1/2 to 11 acres (4-1/4 to 4-1/2 hectares). * A 14 ft.
OPERATION REEL SPEED For best feeding of crop into the sickle and auger, reel speed should be just faster than ground speed. This gently sweeps crop across sickle into auger. Excessive reel speed causes undue wear of reel components and unnecessary load on reel drive, resulting in uneven reel motion. 922 and 933 Headers See Windrower Tractor Operator's Manual for identification and instructions for use of reel speed control in cab.
OPERATION REEL PICK-UP FINGER PITCH Another factor in effective feeding of crop into the sickle and auger is finger pitch angle (the angle the fingers operate at in relation to the ground). NOTE: In the illustration at right, pitch angle (A) is more aggressive than pitch angle (B). Generally it should not be necessary to adjust the finger pitch angle, however in certain crop types and conditions adjustment of the finger pitch may be required to achieve best results.
OPERATION CUTTING HEIGHT Your header will be equipped with either: • wide adjustable outer skid shoes, or • gauge rollers plus narrower skid shoes. Vary the cutting height by adjusting either skid shoe or gauge roller position. The operator can then lower the header to the ground, allowing the shoes or rollers to provide a consistent cutting height. NOTE: Lowering the skid shoes or gauge rollers raises the cutting height. (Gauge rollers allow higher settings than skid shoes.
OPERATION HEADER ANGLE The header (or guard) angle is adjustable in the following range depending on tractor model (measured with cutterbar on ground): Tractor models: XX40/XX50 8° to 16° below horizontal XX52/XX52i c/w shallow angle kit 8° to 16° below horizontal XX52/XX52i w/o shallow angle kit 11° to 18° below horizontal Header angle is adjusted by lengthening or shortening the tractor lift linkage center link. Choose an angle that maximizes performance for your crop and field conditions.
OPERATION AUGER MOUNTED CROP DEFLECTORS/STRIPPERS & STRIPPER BAR EXTENSIONS: 912 & 922 HEADERS Four rubber finger assemblies are mounted to the auger to direct crop rearward to the hay conditioner such that material is evenly distributed across the full width of the conditioner. If too much “end feeding” of conditioner rolls is occurring, remove two outboard rubber finger assemblies (A). If too much “Center Feeding” of conditioner rolls is occurring, the following may be necessary: 1.
OPERATION HAY CONDITIONER ROLL INTERMESH The intermeshing steel rolls of the hay conditioner crimp the plant stems in several places, allowing moisture release and faster drying. The degree to which the stems are conditioned (crimped) depends on the amount of roll intermesh. ROLL INTERMESH ADJUSTMENT Correct conditioning of alfalfa, clover and other legumes is usually indicated when 90% of the stems show crimping but no more than 5% of the leaves are damaged.
OPERATION HAY CONDITIONER ROLL TENSION SPRINGS The conditioner roll intermesh is maintained by two tension springs to provide roll pressure for correct conditioning of the crop. These springs also allow the rolls to open to allow passage of small solid objects without damage to the rolls. The roll tension has been factory set for normal operating conditions and generally does not require adjustment.
OPERATION HAY CONDITIONER FORMING SHIELDS CAUTION: Keep forming shields installed at all times conditioner is in use. Do not allow anyone to stand behind the machine while operating. Stones or other foreign objects may be ejected from the conditioner with considerable force. The side and rear deflectors, and deflector fins are adjustable to shape the windrow to your preference.
OPERATION HAY CONDITIONER FORMING SHIELDS (continued) Forming Shield Height Depending on the amount of crop material, the rear of the forming shield assembly can be raised or lowered to properly deflect the crop. For heavier crops use the higher settings: • XX40 & XX50 series tractors use 4th or 5th hole from the bottom on the rubber strap. • XX52/XX52i tractors use 1st or 2nd hole from the bottom of rubber strap. For lighter crops, lower forming shield as required to form the most uniform windrows.
OPERATION HAYING TIPS There is one certainty when making hay - a fast cure will maintain top quality. It is critical to have the cured hay baled as quickly as possible, for two reasons: 1. Every day hay lies on the ground, 5% of the protein is lost. 2. The sooner the cut hay is off, the earlier the start for next growth. Generally, leaving the windrow as wide and thin as possible makes for the quickest curing, however there are other factors that affect curing time: 1.
OPERATION "GRASS SEED SPECIAL" HEADER J The grass seed auger header has several features to adapt it to this special application. These features include: G Stub Guards and Hold-downs: The cutterbar is equipped with stub guards for effective cutting in tough grass crops. See "Sickle and Sickle Drive" in Maintenance/Service section for maintenance of these components. H Special Auger Design: The center beaters and beater supports have been removed to reduce auger wrapping.
UNPLUGGING THE HEADER OPERATION A WARNING: Stop engine and remove key from ignition before removing plugged material from header. If the sickle plugs: 1. Stop forward movement of the windrower and disengage header drive clutch. 2. With header on ground, back up several feet and engage header drive clutch. 3. If plug does not clear, disengage header drive clutch and raise header fully. 4. Shut off engine, remove key and engage park brake. 5. Engage header lift cylinder stops.
OPERATION TRANSPORTING THE HEADER See "Transporting the Windrower" in Windrower Tractor Operator's Manual for recommended procedures for: · Driving the Windrower on Roads · Towing the Windrower on a Trailer · Towing the Windrower without a Trailer NOTE: For headers with divider rods, when transporting on a side-mount trailer, remove divider rods to narrow the transport width.
OPERATION STORAGE PROCEDURE Do the following at the end of each operating season: CAUTION: 1. Clean the windrower thoroughly. Never use gasoline, naphtha or any volatile material for cleaning purposes. These materials may be toxic and/or flammable. 2. Store machine in a dry, protected place if possible. 3. Cover cutterbar and sickle guards to prevent injury from accidental contact. Also: 4. Repaint all worn or chipped painted surfaces to prevent rust. 5. Loosen all drive belts. 6.
MAINTENANCE/SERVICE SERVICE PROCEDURES CAUTION: To avoid personal injury, before servicing machine or opening drive covers: 1. Fully lower header.
