3.16 Operating the Mower Conditioner

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 increases productivity. As well, proper adjustments and timely maintenance
will increase the length of service you receive from your machine.
The variables listed in Table
pages will affect the performance of your mower conditioner. You will quickly become adept at adjusting your machine
to produce the desired results. Although most of the adjustments have been set at the factory, the settings can be
changed to suit your crop conditions.

3.16.1 Mower Conditioner Float
Mower conditioner float springs are normally set so a force of approximately 95–105 lbf (426–471 N) is required to
lift either end of the mower conditioner just off the ground when the hitch is centered.
In rough or stony conditions, however, it may be preferable to apply less force in order to protect cutting components.
NOTE:
When float setting is light, it may be necessary to reduce ground speed in order to prevent excessive bouncing
and leaving a ragged cut.

Adjusting Float

IMPORTANT:
Float setting (or lifting force) must be equal on both ends of the mower conditioner. Machines with roll
conditioners require the same spring tension on both sides. Machines with finger conditioners require slightly
more tension on the left side.
