6.10 HEADER OPERATION

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.
adjustments and
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 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.

6.10.1 Header Flotation
Header flotation springs are normally set so that
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.
will
When float setting is light, it may be
necessary to use a slower ground speed
to avoid excessive bouncing and leaving a
ragged cut.
a. Set the float fine adjustment to mid-range with
the windrower float adjustment system in the
cab. Refer to the M Series Self-Propelled
Windrower Operator's Manual, Form #169017.
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.
b. Check float by grasping the front corner of
header and lifting. The force to lift should be 95-
105 lbf
approximately the same at both ends.
c. Perform the following steps to adjust the float if
necessary:
1. Raise the header fully, shut down the
engine, and remove the key.
2. Loosen nut (A) on linkage spring drawbolt.
3. Turn drawbolt (B) clockwise to increase float
(makes header lighter) or counterclockwise
to decrease float (makes header heavier).
4. Tighten nut (A) to lock drawbolt.
5. Recheck the float.
