1.3 General Safety
CAUTION
The following are general farm safety precautions
that should be part of your operating procedure for
all types of machinery.
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 footwear with slip resistant soles
Figure 1.2
– Protective glasses or goggles
– Heavy gloves
– Wet weather gear
– A respirator or filter mask
– Hearing protection
Be aware that exposure to loud noise can c ause
impairment or loss of hearing. Wearing suitable
hearing protection devices such as ear muffs or ear
plugs. These will help protect against objectionable
or loud noises.

SAFETY
•Wearclosefitting clothing and cover lo n g hair. Never
wear dangling items such as scarves or bracelets.
• 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.
• Use only service and repair parts, made, or approved by
the equipment manufacturer. Substituted parts may not
meet strength, design, or safety requirements.
• 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.
•Do NOT modify the machine. Non-authorized
modifications may impair machine function and/or safety.
It may also shorten the machine’s life.
Figure 1.5
• 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.
• Keep the area used for servicing machinery clean
and dry. Wet or oily floors are slippery. Wet spots
can be dangerous when working with e lectrical
equipment. Be sure all electrical outlets and tools are
properly grounded.
• Keep work area well lit.
• 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, o r controls.
Clean machines before storage.
• Never use gasoline, naphtha, or any volatile material
for cleaning purposes. These materials may be toxic
and/or flammable.
• When storing machinery, cover sharp or extending
components to prevent injury from accidental contact.

1.4 Maintenance Safety
To ensure your safety while maintaining the machine:
• Review the operator’s manual and all safety items before
operation and/or maintenance of the machine.
• Place all controls in Neutral, stop the engine, set the park
brake, remove the ignition key, and wait for all moving
parts to stop before servicing, adjusting, and/or repairing.
• Follow good shop practices:
– Keep service area clean and dry.
–Besureelectricaloutletsandtoolsareproperly
grounded.
– Use adequate light for the job at hand.
• Relieve pressure from hydraulic circuits before servicing
and/or disconnecting the machine.
• Before applying pressure to a hydraulic system, make
sure all components are tight and that steel lines, hoses,
and couplings are in good condition.
Figure 1.8: Slip on Puddle
• Keep hands, feet, clothing, and hair away from all moving
and/or rotating parts.
• Clear the area of bystanders espec ia lly children when
carrying out any maintenance and repairs or when
making any adjustments.
• Install transport lock or place safety stands under the
frame before working under the header.
• If more than one person is servicing the machine at the
sametime,beawarethatrotatingadrivelineorother
mechanically driven component by hand (for example,
accessing a lube fitting) will cause drive components in
other areas (belts, pulleys, and knife) to move. Stay clear
of driven components at all times.
• Wear protective gear when working on the machine.
• Wear heavy gloves when working on knife components.

1.5 Hydraulic Safety
• Always place all hydraulic controls in Neutral before
dismounting.
• Make sure that all components in the hydraulic system
are kept in good condition and clean.
• Replace any worn, cut, abraded, flattened, or crimped
hoses and steel lines.
• Do not attempt any makeshift repairs to the hydraulic
lines, fittings, or hoses by using tapes, clamps, cements,
or welding. The hydraulic system operates under
extremely high pressure. Such makeshift repairs will fail
suddenly and create a hazardous and unsafe condition.
• Wear proper hand and eye protection when searching for
a high-pressure hydraulic leak. Use a piece of cardboard
as a backstop instead of hands to isolate and identify
aleak.
Figure 1.11: Checking Hydraulic Leaks
• If injured by a concentrated high-pressure stream of
hydraulic fluid, seek medical attention immediately.
Serious infection or toxic reaction can develop from
hydraulic fluid piercing the skin.
• Before applying pressure to a hydraulic system, make
sure all components are tight and that steel lines, hoses,
and couplings are in good condition.

Satisfactory operation of the header in all situations requires making proper adjustments to suit various crops and
conditions.
Correct operation reduces crop loss and increases productivity. As well, proper adjustments and timely maintenance
will increase the length of service you rece ive from the machine.
The variables listed below and detailed on the following pages, will affect the performance of the header.
You will quickly become adept at adjusting the machine to give you the desired results. Most of the adjustments
have been set at the factory but if desired, the settings can be changed to suit crop conditions.

3.12.1 Operating Speed
Performance of the pick-up in va rious crop an d field conditions largely depends upon the speed at w hich the drapers
are turning, and the forward speed of the combine.
• If the swath is pushed ahead, the draper speed is too low, and some of the crop may remain unpicked.
• If the swath is torn apart and is pulled toward the combine header, the draper speed is too high, and uneven
combine feeding will occur.
Generally, optimum pick-up speed for most conditions shall be selected so that the swath is always pushed slightly
ahead.
Draper speed is adjusted from the combine cab by regulating oil flow to the pick-up hydraulic motors, typically usin g
the reel speed controls for the combine. The ratio of pick-up speed to combine ground speed can be set using the
combine header controls. See your combine operator’s manual.
IMPORTANT:
Do NOT over-speed pick-up. Over-speeding the pick-up causes premature wear of drive
components and adversely affects pick-up performance.
The following operating speeds are suggested:
Front and Rear Deck Aft Roller: 51 rpm per 1 mph (1.6 km/h) of combine ground speed.
Example: For combining at 5 mph (8 km/h), the rear roller shaft should run at 51 x 5 mph = 255 rpm
(51 x 8/1.6 = 255 rpm).

OPERATION
Adjusting Draper Speed
Draper speed is determined by measuring the rpm of the
aft roller on the rear pick-up deck.
1. Check the roller rpm (A) with a handheld tachometer,
and adjust with the reel speed control in the combine.
NOTE: Some combines are equipped with a speed
sensor (B) that indicates the roller rpm in the
combine cab.

plied with an auger drive sprocket to match your combine. The auger is driven by a direct
e feeder house, and auger speed depends on the feeder house speed. In certain crops, a higher
speed may be desired. Contact your Dealer for available sprocket options.
n: Auger Drive Sprockets, page 117 for instructions on changing the sprocket.
Auger Position
The auger position is c ritical for a smooth, high capacity flow of crop into the feeder house. It is factory set for normal
crop conditions but may require adjustment for different crops and conditions.
The auger must rotate freely without touching the auger pan or stripper bars, and the position should be checked
prior to operating the pick-up.
The clearance (A) between the auger flighting (B) and
pan (C) should be 3/16–7/16 in. (5–11 mm).

Stripper Plate Clearance
The header is equipped with a pair of stripper plates (A)
located on either side of the center opening, and are
designed to minimize crop carryover behind the auger
when properly adjusted.
Figure 3.72: Right End
• If the clearance between the flighting and stripper plate
is too large, crop will tend to wrap around the auger and
disrupt crop flow into the combine.
• If the clearance is too little, the auger flighting may
contact the stripper plates, and cause excessive wear
to the flighting and stripper plates.
Stripper plate clearance has been set to 1/8–1/4 in. (3–6
mm) at the factory.

The recommended pick-up height is 1 in. (25 mm), and
may need to be changed to suit field conditions.
Two general symptoms will indicate that an adjustment is
required:
• If the pick-up leaves material in the swath, the pick-up
height is too high.
• If the pick-up fingers are wearing quickly or are picking
up dirt and stones, the pick-up height is too low.
Adjusting Pick-Up Height
Adjust the pick-up height as follows:
1. Check that tire pressure is 35–45 psi (240–310 kPa).
2. Adjust the operating height (A) so that the rear roller
is 12 in. (300 mm) off the ground.

2. Apply hydraulic system oil to the O-ring (B).
3. Align the tube or hose assembly so that the flat face
of the sleeve (A) or (C) comes in full contact with
O-ring (B).
4. Thread tube or hose nut (D) until hand-tight. The nut
should turn freely until it is bottomed out.
5. Torque fitting further to the torque value in the table
shown in the opposite column.
NOTE: If applicable, hold the hex on the fitting body (E)
to prevent rotation of fitting body and hose when
tightening the fitting nut (D).
6. When assemb ling unions or two hoses together, three
wrenches will be required.
