OPERATING THE MOWER CONDITIONER
7.4 Roll Timing
For proper conditioning, the rolls must be properly timed
with each steel bar on one roll centered between two
bars (B) of the other roll. The factory setting should be
suitable for most crop conditions.
IMPORTANT
Roll timing is critical when the roll gap is
decreased because:
• Conditioning is affected
• The bars may contact each other
