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.

SAFETY

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.

PROTECT YOURSELF

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.

PROTECT AGAINST NOISE

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.

BE PREPARED FOR EMERGENCIES

SAFETY

GENERAL SAFETY (continued)

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.

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.

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.

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).

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.

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.

LONG DIVIDER RODS	SHORT DIVIDER	A

NOTE: A floating divider kit is available to extend the separation of crop to a point in front of the reel. This can be beneficial in short (up to 75 cm [30 in.]) lodged or standing crop. The floating dividers are also effective in tall standing crop. This attachment is not recommended for tall lodged crops. See Options and Attachments section.

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: At a ground speed of 6 miles per hour (10 km/h) with a 21 ft. header, the area cut in one hour would be approximately 15-½ acres (6 hectares).

Form # 147083	21	Issue 01/07
	21

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.

USE GAUGE WHEEL SPRINGS TO ASSIST FLOTATION

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 midrange 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”.

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. 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.

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.

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.

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.
