6.17 HEADER OPERATION

Satisfactory function of the windrower in all
situations requires making proper adjustments to
suit various crops and conditions.
Correct operation reduces crop loss and allows
cutting of more
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 windrower. You will quickly become adept at
adjusting the machine to give you the desired
results.

IMPORTANT
To prevent structural damage to the
header, do not operate with lean bar
removed.
Use the lean bar adjustment to accommodate
different crop heights.
The lean bar should strike the upper portion of
the crop, leaning it away from the header and
exposing the stalks to the sickle.

6.17.2 Auger Speed
The auger speed must be high enough to carry
the crop into the conditioner and yet not throw it
out. In light crops, a lower throttle setting on the
will
tractor will slow down the windrower operating
speed and help to prevent carryover.

6.17.2.1 Auger Speed, A30-S and A30-D

The A30 auger speed is fixed to the engine rpm
and an optional 19 tooth drive sprocket provides
lower auger speeds.
Refer to Section 5 SPECIFICATIONS for
available auger speeds at rated tractor RPM.
