Satisfactory operation of the mower conditioner
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 mower conditioner. You will quickly become
adept at adjusting the machine to give you the
desired results.

6.13.1 Cutting Height
Cutting height is determined by the angle of the
cutterbar/header which can be adjusted with the
center link, either hydraulically or mechanically.
Optional adjustable gauge rollers or skid shoes
are available for 16 ft headers to also provide
different cutting heights. Refer to Section 8,
Options and Attachments.
Cutting height should be adjusted for optimum
cutting performance without allowing excessive
build-up of mud and soil inside the header which
can lead to poor crop flow and increased wear
on cutting components.
