• 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 wh en working with electrical
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, or controls.
Clean machines before storage.

• Never use gasoline, naphtha, or any volatile material
for cleaning purposes. These materials may be toxic
and/or flammable.

6 Operating the Header

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 receive f rom the machine.

The variables listed below and detailed on the following pages will affect the performance of the header. You will
quickly become familiar with adju sting the machine to give you the desired results. Most o f the adjustments have
been set at the factory, but if desired, the settings can be changed to suit crop conditions.

6.1 Header Float

Header float springs are normally set so 95–105 lbf (426–471 N) is required to lift either end of the header just off
the ground.

In rough or stony conditions, it may be desirable to maintain a lighter setting to protect cutting components.

When float setting is light, it may be necessary to use a slower ground speed to avoid excessive bouncing resulting
in a ragged cut. Faster ground speeds may require additional ground pressure.

OPERATING THE HEADER

6.1.1 Adjusting Header Float

Set the Float Fine Adjustment to MID-RANGE with the windrower float adjustment system in the cab. Refer to your
windrower operator’s manual.

DANGER

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.

Check the float by grasping the front corner of header and lifting. The force to lift should be 95–105 lbf (426–471 N),
and should be approximately the same at both ends.

If it is necessary to adjust the float, perform the following steps:

1. Raise the header fully, shut down the engine, and
remove the key.

2. Turn drawbolt (A):

a. Clockwise to INCRE ASE float (m ak es

6.3 Roll Tension

The roll tension (the force holding the rolls together) is achieved with a spring type adjustable linkage that is preset
to maximum at the factory.

Heavy crops or tough forage that tend to separate the rolls require the maximum roll tension to ensure that material
is sufficiently crimped.

Light alfalfa and short grasses would require less roll tension to minimize over-conditioning.

The position of the forming shields controls the width and placement of the windrow. The decision on forming shield
position should be based on the following factors:

• weather conditions (rain, sun, humidity, wind)

• type and yield of crop

• drying time available

• method of processing (green-feed, bales, silage)

A wider windrow will generally dry faster and more evenly resulting in less protein loss. Fast drying is especially
important in areas where the weather allows only a few days to cut and bale. R efer to Section 6.14 Haying Tips,

A narrower windrow may be preferred for ease of pickup and when drying is not critical (for example, when cutting
for silage or green-feed).

deflector (A) by pushing down on one side of the
deflector and then on the other side.

NOTE: Locking handles (B) are located at
