HARVEST HEADERS

OPERATOR’S MANUAL

Form 147277 Issue 10/04 Sugg. Retail: $15.00

INTRODUCTION

Your new 963 Harvest Header is designed to serve a dual function in your grain and specialty crop harvesting operation:

1. Teamed with your self-propelled windrower power unit, the header will cut and lay crop into uniform fluffy windrows. Windrowing allows starting the harvest earlier, protects the crop from wind damage, and gives you more flexibility in scheduling combine time. (The left deck of the 963 Header can be manually shifted over the center opening to deliver crop to the end of the header, which allows using your combine as the power unit when windrowing.)

2. When conditions are right for straight cutting, the header can quickly be attached directly to your combine with the addition of an adapter. When weather is not a critical factor, straight cutting eliminates the windrowing operation.

NOTE: This manual contains information on the Harvest Header. It must be used in conjunction with your Windrower, Tractor and/or Combine Operator's Manual. As well, a separate manual is provided for the adapter that is required to allow attachment of the header to the various makes and models of combines and tractors.

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 Harvest 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 familiarize yourself with how the material is organized.

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 operators position, facing forward.

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 ear muffs (A) or ear plugs (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.

HEADER OPERATION

Operating Variables

Satisfactory function of the header requires making the 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 at right will affect the performance of the header. You will quickly become adept at adjusting the machine to give you the desired results.

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. See "Windrowing" for affects of ground speed on windrow formation.

• 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 two header sizes.

Example shown approximately 22 acres (9 hectares) per hour.

: At a ground speed of 5 miles per hour (8 km/h) with a 36 ft. header, the area cut would be

1. Ground Speed

2. Cutting Height

3. Header Flotation

4. Header Angle

5. Draper Speed

6. Delivery Opening Width

7. Reel Speed

8. Reel Height

9. Reel Fore-Aft Position

10. Divider Angle

Operating Variables (continued)

CUTTING HEIGHT

Cutting height will vary, depending on whether windrowing or straight-cutting, type of crop, etc. See "Windrowing" for stubble height recommendations.

Gauge Wheel Field Positions:

For headers equipped with gauge wheels or the gauge wheel/transport package, choose Field Position 1 or 2 to maintain proper gauge wheel spring force at desired cutting height.

Field Position 1

ground (4 to 12 in. [100 to 300 mm] cutting height.

Field Position 2

(0 to 4 in. [100 mm] cutting height).

NOTE: When changing gauge wheel field position, readjust header flotation. See "Header Flotation" in Windrower Tractor or Combine Adapter Operator's Manual.

NOTE: Gauge wheel field position should also be related to Header Angle. Use Position 2 for flatter header angles and Position 1 for steeper header angles.

2. Reduce scooping of dirt onto cutterbar.

3. Provide a method of setting a minimum cutting

height.

To adjust skid shoes:

1. Raise header and engage lift cylinder stops.

2. Remove one of the guard bolts securing

support (S).

3. Remove rods from supports and position shoe

at desired setting. Adjust both shoes to the same position to provide an even cutting height. NOTE: When using the "flattest" setting, (Position 1), ensure angle (A) is removed to prevent draper damage.

4. Replace rods in supports and replace guard

bolt.

NOTE: The skid shoe kit includes two shoes. Additional skid shoes may be installed if required.

DANGER: To avoid bodily injury or

death from fall of raised header,

always engage cylinder stops before

going under header.

Operating Variables (continued)

HEADER FLOTATION

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

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

Under normal conditions, adjust float spring tension so 50 to 70 lbs. force (220 to 310 N) is required to lift cutterbar off ground at each end.

See "Header Flotation" in Windrower or Combine Adapter Operator's Manual for adjustment details.

HEADER ANGLE

The header (or guard) angle can be set between 9° and 13° below horizontal on the windrower.

The header (or guard) angle can be set between 13° and 16° below horizontal on the combine. (Actual range may vary with combine set-up.)

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.

See "Windrowing" for the effects of header angle on windrow formation. See "Header Angle" in Windrower or Combine Adapter Operator's Manual for adjustment details.

For headers with gauge wheels, see "Gauge Wheel Field Positions", page 18 for proper relationship between gauge wheel setting and header angle.

DRAPER SPEED

Draper speed affects the orientation of stalks in the delivered crop. See "W indrowing", page 26 for the affect of draper speed on windrow formation. See W indrower or Combine Adapter Operator's Manual for adjustment details.

DELIVERY OPENING WIDTH

For windrower, the width and position of the delivery opening affects the width and configuration of the windrow. See "Windrowing", page 26 for more information.

For straight cutting, the side draper opening must be set to properly overlap feeder draper.

The center delivery opening can be adjusted to widths between 32.3" (820 mm) and 65.8" (1670 mm) measured between rollers.

NOTE: End delivery opening size is limited by windrower drive tires and/or deck contacting header frame. When shifting deck to end delivery, ensure center mm) or narrower.

delivery opening size is 61" (1549

To adjust delivery opening width:

1. Release draper tension as follows:

• Loosen bolt (A) and nut (B).

• Slide bracket (C) towards

3. continued) Bolt opening adjustment bars to deck at the hole corresponding to the draper row. For example if drapers are to be connected at row E (from chart on previous page), move roller until hole (E) aligns with deck mounting slot. Use a carpenter’s square to ensure roller is square to deck and tighten hardware.

NOTE: For access to bolt securing the adjustment bar at cutterbar on L/H (moveable) deck, remove retainer clips (G) and, if installed, the front edge draper seals and clips (see page

48). Raise front of deck for access to bolt.

4. 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 21. 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.

5. NOTE: Place connector tube so holes closest to end of tube are at the cutterbar. Connect draper with screw heads facing center opening.

NOTE: To reduce the opening size after it has been enlarged, a short section of draper (available from your dealer) can be added to increase draper length.

6. Slide bracket (C) away far as hand force allows. Check that draper Vguide (E) is properly engaged in grooves at rear of both rollers.

7. Tighten nut (B) to secure the position of bracket (C).

8. Apply draper tension by turning bolt (A) clockwise until gap between idler spring coils is 1/16 inch (1.5 mm). IMPORTANT: Do not collapse spring. The spring maintains draper tension and prevents over-tension. If spring is collapsed, damage to draper and rollers may result from excessive draper tension.

Operating Variables

END DELIVERY: The left deck of the 963 header

can be manually shifted to close off the center opening and deliver crop to the left end of the header. This provides the capability of windrowing with a combine or non-windrower tractor as the power unit.

To shift left deck:

1. Reverse draper travel by disconnecting hydraulic hoses at (B) and connect to opposite lines.

2. Remove deck retainer clips at cutterbar, item (G) on previous page. (If front edge draper seals are installed at cutterbar, remove these seals and clips as well.)

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.

5. Lengthen center link between header and

adapter to steepest header angle to increase clearance to header back sheet

6. Loosen bolts (C) at both clamps on left deck. Attach a "Come-Along" from a sickle guard to the deck cross member (A) as shown. Move deck to the right 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.

7. Tighten bolts (C) at both clamps.

8. Readjust center link to achieve desired header

operating angle.

9. Reinstall deck retainer clips (and front edge draper seals, if required).

10. 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 (2 or 3 tines, depending on drum size).

11. Adjust header flotation to compensate for the

shift in weight. See "Header Flotation" in Windrower or Combine Adapter Operator's Manual.

12. For rotary combines with narrow feeder opening,

increase delivery opening width to be suitable for windrowing. See "Delivery Opening Width", beginning on page 20.

Operating Variables (continued)

REEL SPEED

• Reel speed affects 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.

• A faster reel speed may be necessary in leaning or down crop.

• Excessive shattering of grain heads or crop loss over the header back tube may be indications that reel

speed is too fast.

REEL HEIGHT

• In standing crop, adjust reel height so bat contacts the plants just below the head, and carries material

through the sickle onto the drapers.

• Down crop may 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 bats.

• For reel clearance to cutterbar adjustment, see Maintenance/Service section, page 49.

REEL POSITION - FORE & AFT

Reel fore-aft position can be adjusted to suit various crop conditions:

• For straight standing crop, the reel position is

normally centered above the cutterbar.

• For crops that are down, tangled, or leaning,

move reel ahead of cutterbar.

• Disturbance of crop on the drapers by the reel

bats may be an indication that the reel is too far back.

To adjust reel fore-aft position:

1. Lower reel so support arms are horizontal.

2. Back off jam nut on positioning screw (A) at each arm.

3. Loosen screw (A) and slide reel mounting channel (B). Pry bar may be used at hole (C).

4. Tighten screw into selected hole position and secure with jam nut.

5. Be sure screw is in the same hole at each arm.

6. Check reel clearance to cutterbar. See Maintenance/Service section.

NOTE: If reel fore-aft position is changed by more than two holes, check and adjust header flotation.

NOTE: For 36' center arm, positioning screw is on top of mounting channel. (There is no jam nut on positioning screw at center arm.)

Operating Variables

DIVIDER ANGLE

The dividers can be angled in or out to provide proper separation and clean entry in a variety of crops. Divider gather is factory set at approximately 1.5 inches (40 mm). In tangled crops like canola, it may be necessary to reduce gather.

To adjust angle, loosen hardware (A), position divider and tighten hardware.

NOTE: On left side, ensure that front hinge pin of side shield remains covered.

DIVIDER ANGLE ADJUSTMENT

Shut Down Procedure

CAUTION: Before leaving operator's seat for any reason:

1. Park on level ground if possible.

2. Lower the header and reel fully.

3. Place all controls in NEUTRAL or PARK.

4. Disengage header drive.

5. Engage the park brake.

6. Stop engine and remove key from ignition.

7. Wait for all movement to stop.

HEADER OPERATION

Windrowing

The factors listed below will all affect the formation of the windrow. You will quickly become adept at adjusting these variables to achieve the desired results.

NOTE: Crop condition is a major factor in forming a good windrow. While standing or uniformly leaning crops can generally be easily formed into an acceptable windrow, such is not the case when stalks are tangled or leaning in several directions.

GROUND SPEED

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

Ground speed affects the orientation of stalks in the windrow. Increasing ground speed will cause the configuration of the windrow to go from parallel formation to herringbone or dovetail. See "Windrow Characteristics" in this section.

CUTTING HEIGHT

For grain crops the windrow should normally be laid on stubble from 6 to 8 inches high (150 - 200 mm).

Benefits of a stubble of this height:

• Allows free circulation of air under the windrow for more even drying.

• Supports the windrow without bending.

• Keeps grain heads from contacting ground. Heads that touch the ground are difficult to pick up and will

sprout in damp weather.

HEADER ANGLE

Steeper draper angles tend to form herringbone or dovetail configurations, while flatter draper angles form parallel or fantail windrows. See "Windrow Characteristics" in this section.

DRAPER SPEED

Draper speed affects the orientation of stalks in the windrow. Faster draper speeds will tend to form herringbone or dovetail configurations. See "Windrow Characteristics" in this section.

REEL SPEED

Reel speed affects the smoothness and evenness of the windrow. Operating the reel too fast or too slow relative to ground speed will cause bunching.
