Roll Timing
For proper conditioning, the rolls must be properly timed with the bar on one roll centered between two bars on the other
roll. The factory setting should be suitable for most crop conditions.
Figure 3.62: Properly Timed Rolls
IMPORTANT:
Roll timing is critical when the roll gap is decreased because
conditioning is affected and the bars may contact each other.
Checking Roll Timing
Check roll timing if excessive noise is coming from the conditioner rolls.

Roll timing is factory-set and should not require adjustment; however, if there is excessive noise coming from the
