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 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 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 knife.
To extend or retract lean bar, re-position
hardware in adjustment holes as required. Refer
to illustration.
