3.10.3 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.
DANGER
To avoid bodily injury or death from unexpected startup of the machine, always stop the engine and remove the key
from the ignition before leaving the operator’s seat for any reason.
Roll timing is factory-set and should not require adjustment; however, if there is excessive noise coming from the
conditioner rolls, the timing will need to be adjusted. Refer to Adjusting Roll Timing, page 51.
