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.
BE PREPARED FOR EMERGENCIES

SAFETY
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 independent 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. Unauthorized
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.

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.

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.

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.

Skid Shoes
Skid shoes are available as an attachment. The
primary benefits of skid shoes are:
1. Help prevent damage to cutting components.
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

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.

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.

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",

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.)

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.
