7.9 HEADER OPERATING VARIABLES

Satisfactory function of the header 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 below and detailed on the following pages will affect the performance of the machine. You will quickly become adept at adjusting the machine to give you the desired results.

The proper setting requires ‘balancing’ the amount of header weight carried by the float and the stabilizer wheels.

Refer to Section 7.8.1 Header Settings for recommended use in specific crops and crop conditions.

CAUTION

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.

a. Raise the header so that the stabilizer wheels

are off the ground. Shut down engine, and remove the key.

b. Check that the float is working properly. See

Section 7.9.2 Header Float.

c. Set up the stabilizer wheels, if installed, as

follows: Otherwise, proceed to step d. on next page.

CAUTION

Handle may be under tension, especially when the wheels are on the ground. Raise header so that wheels are off the ground before making adjustments.

7.9.1 Cutting Height

Harvest Headers are designed to allow an Operator to cut the crop above the ground for a desired stubble height, or to cut the crop at ground level with the header on the ground.

Cutting height will vary, depending on factors including whether windrowing or straightcutting, type of crop, etc.

7.9.1.1 Cutting Off The Ground

Cutting height is controlled with a combination of header lift cylinder adjustment and a stabilizer wheel system, or a stabilizer/slow speed transport wheel system.

The stabilizing wheel system in both options is designed to minimize bouncing at the header ends, and may be used to float the headers to achieve an even cutting height when cutting above ground level in cereal grains.

The system can provide very even stubble height and greatly reduced operator fatigue.

Continuous operation with excessive spring compression (i.e. load indicator reading greater than #4) can result in damage to suspension system.

e. Adjust header angle to desired working angle

with the machine’s header angle controls. If angle is not critical, set it to mid-position.

f. Use the combine AHHC to automatically

maintain cutting height. Refer to your combine Operator’s Manual and AHHC instructions for details.

NOTE

Header angle adjustments or AHHC ground pressure control may be used for ’on-the-go’ cut height adjustments.

169593 64 Revision B

SECTION 7. OPERATION

7.9.1.2 Cutting On The Ground

Cutting on the ground is controlled with a combination of skid shoes, header angle, and float adjustment, and not with the header lift cylinders.

NOTE

Skid shoes are standard equipment on the D65 header.

Having the header ride on the skid shoes allows the float linkage to float the header over obstacles and follow ground contours, rather than supporting the header with the cylinders.

Lowering the skid shoes or decreasing the header angle increases the cutting height. This may be desirable in stony conditions, to reduce damage to cutting components. Also, a longer stubble length helps material dry faster.

Raising the skid shoes and increasing the header angle allows the crop to be shaved.

Refer to Section 7.8.1 Header Settings for recommended skid shoe positions in specific crops and crop conditions.

Set up the header as follows:

a. Fully raise the stabilizer wheels, or slow speed

transport wheels if installed. Refer to previous section.

1. Remove lynch pin (A) at each skid shoe (B).

2. Hold shoe, and remove pin (C) by disengaging frame, and then pulling away from shoe.

3. Raise or lower skid shoe to desired position using holes in support as a guide.

4. Re-install pin (C), engage in frame, and secure with lynch pin (A).

Inner Skid Shoes

1. Remove lynch pin (D).

2. Hold shoe (E), and remove pin (F) by pulling down to disengage frame, and then pulling away from shoe.

3. Raise or lower skid shoe (E) to desired position using holes in support (G) as a guide.

DANGER

To avoid bodily injury or death from unexpected start-up or fall of raised machine, stop engine, remove key, and engage lift cylinder stops before going under machine to adjust skid shoes or for any reason.

b. Fully raise header, engage lift cylinder stops,

shut off engine and remove key.

c. Adjust skid shoes to achieve desired cutting

height as follows:

Outer Skid Shoes

4. Re-insert pin (F), engage in frame, and secure with lynch pin (D).

d. Check that skid shoes are adjusted to the same

f. Check header float as described in the following

Section 7.9.2 Header Float.

169593 65 Revision B

SECTION 7. OPERATION

7.9.2 Header Float

D65 combine headers perform best with minimum extra weight on the header, under normal conditions.

The function of the header float locks is to lock and unlock the header float system. There are two locks - one on each side of the adapter.

IMPORTANT

The float locks must be engaged when the header is being transported with the adapter attached so there is no relative movement between the adapter and header during transport.

The float locks must also be locked during detachment from the combine to allow the feeder house to release the adapter.

n. To increase float (lighten header), turn bolts

(H) and (J) clockwise.

NOTE

Loosen jam nuts on adjuster bolts before adjusting, and re-tighten once complete.

o. To decrease float (increase header weight),

turn bolts (H) and (J) counterclockwise.

p. Use the following guidelines when adjusting

float:

1. For Single Knife Headers: Adjust the float

so the wrench reading is equal for both sides.

2. For 40 and 45 ft. Double Knife Headers:

Adjust the float so that torque settings are equal for both sides, and then loosen both right side spring bolts two turns.

3. Turn each bolt pair equal amounts. After

adjustment has been made, repeat torque wrench reading procedure.

4. 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.

5. With a light float setting, it may be

necessary to use a slower ground speed to avoid excessive bouncing and leaving a ragged cut.

6. The stabilizer wheels may be used in

conjunction with float to minimize bouncing at the header ends and control cut height when cutting off the ground. Refer to Section 7.9.1 Cutting Height for details.

7.9.2.3 Setting Feeder House Height and Header Angle

a. Adjust feeder house height while watching float

indicator (K) to set cutterbar down force (normally 2 on indicator). Lower feeder house height to increase ground pressure (decrease float). Indicator reading will increase.

NOTE

Installation of the auto header height controller attachment is recommended for cutting on the ground if the combine is equipped to interface with it.

b. When cutting on ground, adjust header angle to

achieve desired stubble height. Header angle indicator (L) indicates A for shallowest angle/higher stubble, and D for steepest angle/lower stubble.

c. Decrease header angle to minimize pushing

soil.

NOTE

Header angle and reel fore-aft position changes do not significantly affect header float (downforce).

169593 68 Revision B

169593 69 Revision B

7.9.4 Reel Speed

SECTION 7. OPERATION

7.9.4.1 Optional Reel Drive Sprockets

Reel speed affects feeding of crop into the sickle and onto the drapers, as well as the smoothness and evenness of the delivered crop.

Operating the reel too fast or too slow relative to ground speed will cause bunching. At the proper speed, the reel discs 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 the ground, reel speed may be too fast.

In standing crop, reel speed should be just faster than or equal to ground speed, sweeping crop across the sickle.

Flattened crop or a crop that is leaning away from the cutterbar requires a higher reel speed in relation to ground speed. This can be achieved by increasing reel speed, decreasing ground speed, or both.

Excessive shattering of grain heads or crop loss over the header back tube may be indications that reel speed is too fast. Excessive reel speed causes undue wear of reel components and unnecessary load on reel drive, resulting in uneven reel motion.

169593 70 Revision B

SECTION 7. OPERATION

7.9.5 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, reduce ground speed to reduce loads on cutting components and drives.

When cutting very light crops (e.g. short soybeans), ground speed may have to be reduced to allow reel to pull in small and short plants.

Start at 3.0–3.5 mph (4.8–5.8 km/h), and adjust as required.

Higher ground speeds require heavier float settings to prevent excessive bouncing that would result in increased cutting component damage. In most cases, 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 below: At a ground speed of 6 miles per hour (9.7 km/h) with a 45 ft. header, the area cut in one hour would be approximately 33 acres (13.4 hectares).

SECTION 7. OPERATION

7.9.10 Reel Tine Pitch

IMPORTANT

The following describes the concept and operational guidelines of the pickup reel. Please read carefully before operating the machine.

7.9.10.1 Concept

The pickup reel is designed to pick up flattened and severely lodged crops.

It is not always necessary to increase the tine pitch (higher cam setting) to pick up crops that are lodged, but rather, the cam settings are mainly used to determine how the crop will get delivered to the drapers.

The position of the fingers relative to ground (tine pitch) is not significantly affected by the cam setting. For example, the cam position range is 33 degrees, but the corresponding finger pitch range is only 5 degrees at the lowest point of reel rotation.

For best performance, use the minimum cam setting that will deliver the crop past the rear edge of the cutterbar and onto the drapers.

7.9.10.2 Operating Guidelines

The following outlines the function of each cam setting and includes guidelines for set-up in various crop conditions. The setting numbers are visible above the slots on the cam disc. Refer to Section 7.9.10.3 Cam Adjustment.

 Cam Position 1: Delivers the most even

crop flow onto the drapers without fluffing up or disturbing the material. The crop is released quite close to the cutterbar, and works best with the cutterbar on the ground. Some crops will not be delivered past the cutterbar when the cutterbar is raised off the ground, and the reel is pushed forward. Initially, have the reel speed set about equal to the ground speed.

 Cam Position 2: Recommended starting

position for most crops and conditions. This setting gives a fingertip speed approximately 20% faster than the reel speed.

o If crops tend to stall on the cutterbar

with the reel in a forward position, the cam setting should be increased to push the crop past the rear edge of the cutterbar.

o If the crop getting fluffed, or the flow

across the drapers is disrupted, the cam setting should be decreased.

 Cam Positions 3 and 4: Mainly used to

leave long stubble. Allows the reel to reach forward and lift the crop a onto the drapers. The further forward the reel, the higher the cam setting should be.

 Cam Position 4 would be used with the

reel being fully forward to leave maximum amount of stubble in lodged crops. This setting gives a finger tip speed approximately 30% faster than the reel speed.

 Cam Position 4, Header Angle At

Maximum, and Reel Fully Forward

provides maximum amount of reel reach below cutterbar to pick up lodged crops, and gives a finger tip speed approximately 35% faster than the reel speed.

Cutting height is set to approximately 8 inches (203 mm) to leave a significant amount of stubble. In damp materials such as rice, it is possible to double ground speed because the amount of material that is being cut is less.

NOTE

High cam settings with the reel fore-aft position at 4–5, severely decrease the draper capacity because the reel disrupts crop flow across the drapers. The fingers are still engaged in the crop that is moving on the drapers.

High cam settings are recommended only with the reel at or close to full forward settings.

IMPORTANT

The reel to cutterbar clearance should always be checked following adjustments to reel tine pitch and reel fore-aft position.

Refer to Section 8.12.1 Reel Clearance to Cutterbar.

Refer to Section 7.8.1 Header Settings for recommended reel tine pitch in specific crops and crop conditions.

169593 86 Revision B

SECTION 7. OPERATION

7.15 TRANSPORTING HEADER

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.

7.15.1 Combine

CAUTION

 Check local laws for width regulations

and lighting or marking requirements before transporting on roads.

 Follow all recommended procedures in

your Combine Operator's Manual for transporting, towing etc.

 Disengage header drive clutch when

travelling to and from the field.

 Before driving combine on a roadway,

be sure flashing amber lamps, red tail lamps and head lamps are clean and working properly. Pivot amber lamps for best visibility by approaching traffic. Always use these lamps on roads to provide adequate warning to other vehicles.

 Do NOT use field lamps on roads, they

may confuse other drivers.

 Before driving on a roadway, clean slow

moving vehicle emblem and reflectors. Adjust rear view mirror and clean windows.

 Lower the reel fully and raise header

unless transporting in hills. Maintain adequate visibility and be alert for roadside obstructions, oncoming traffic and bridges.

 When travelling downhill, reduce speed

and keep header at a minimum height. This provides maximum stability if forward motion is stopped for any reason. Raise header completely at bottom of grade to avoid contacting ground.

 Travel speed should be such that

complete control and machine stability are maintained at all times.

7.15.2 Towing

The header can be towed behind the combine or with the Slow Speed Transport/Stabilizer Wheel option, or on an approved header transporter. Refer to your Combine Operator’s Manual, or see your MacDon Dealer.

7.15.2.1 Attaching Header To Towing Vehicle

CAUTION

 To avoid bodily injury and/or machine

damage caused by loss of control:

 Weight of towing vehicle must exceed

header weight to ensure adequate braking performance and control.

 Do NOT tow with any highway capable

vehicle. Use only an agricultural tractor, agricultural combine, or properly configured MacDon windrower.

 Ensure that reel is down and fully back

on support arms to increase header stability in transport. For headers with hydraulic reel fore-aft, never connect the fore-aft couplers to each other. This would complete the circuit, and allow the reel to creep forward in transport, resulting in instability.

 Check that all pins are properly secured

in Transport position at wheel supports, hitch and cutterbar support.

 Check tire condition and pressure prior

to transporting.

 Connect hitch to towing vehicle with a

proper hitch pin with a spring locking pin or other suitable fastener.

 Attach safety hitch chain to towing

vehicle. Adjust safety chain length to remove all slack except what is needed for turns.

 Connect header wiring harness 7-pole

plug to mating receptacle on towing vehicle. (The 7-pole receptacle is available from your MacDon Dealer Parts Department).

 Ensure lights are functioning properly,

and clean the slow moving vehicle emblem and other reflectors. Use flashing warning lights unless prohibited by law.

SERVICING

The following instructions are provided to assist Operator in the use of header.

Detailed maintenance, service, and parts information are contained in the Technical Manual and the Parts Catalog which are available from your MacDon Dealer.

8.1 PREPARATION FOR SERVICING

CAUTION

To avoid personal injury, before servicing header or opening drive covers:

1. Fully lower the header. If necessary to service in the raised position, always engage lift cylinder stops.

2. Stop engine, and remove key.

 Be prepared if an accident should occur.

Know where the first aid kit and fire extinguishers are located and how to use them.

3. Engage park brake.

4. Wait for all moving parts to stop.

8.2 RECOMMENDED SAFETY PROCEDURES

 Park on level surface when possible.

Block wheels securely if combine is parked on an incline. Follow all recommendations in your Combine Operator's Manual.

 Wear close-fitting clothing, and cover

long hair. Never wear dangling items such as scarves or bracelets.

 Wear protective shoes with slip-

resistant soles, a hard hat, protective glasses or goggles and heavy gloves.

 If more than one person is servicing the

machine at the same time, be aware that rotating a driveline or other mechanically driven component by hand (for example, accessing a lube fitting) will cause drive components in other areas (belts, pulleys, and sickle) to move. Stay clear of driven components at all times.

 Keep the service area 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.

 Use adequate light for the job at hand.  Replace all shields removed or opened

for service.

 Use only service and repair parts made

or approved by the equipment manufacturer. Substituted parts may not meet strength, design or safety requirements.

 Keep the machine clean. Never use

gasoline, naphtha or any volatile material for cleaning purposes. These materials may be toxic and/or flammable.
