Roll Conditioner
Rolls condition the crop by crimping and crushing the stem in several places, allowing the release of moisture resulting in
faster drying times.
3.14.1
Conditioner Roll Gap
The roll gap is the distance between the two conditioner rolls. The roll gap controls the degree to which crop is conditioned
as it passes through the rolls. The roll gap is factory-set at approximately 6 mm (1/4 in.).
Steel rolls can be operated over a larger range of roll gap settings, since they are able to intermesh, and are therefore
suited to a wider range of crops, from alfalfa to thicker-stemmed cane-type crops. They are capable of a roll gap of up to
25 mm (1 in.); however, too large a gap may cause crop feeding problems.
Grass-type crops may require a smaller gap for the proper feeding and conditioning of cut crop.
Checking Roll Gap
To prevent equipment damage, check the size of the roll gap when you are using a roll gap setting smaller than that set at
the factory.
IMPORTANT:
Choose the roll gap setting that is suitable for your crop conditions. Refer to
3.14.1 Conditioner Roll Gap, page 55
for
factory and custom roll gap settings.
DANGER
To prevent injury or death from the unexpected start-up of the machine, always stop the engine and remove the key
from the ignition before leaving the operator
’
s seat for any reason.

Steel rolls:
The length of thread (A) extending above the
jam nut on the adjustment rods can be used as an
approximation of the roll gap. However, this method does
NOT
provide consistent roll gap measurements. The roll gap
factory setting for steel rolls is 6 mm (1/4 in.). If
adjustments are required, refer to
for adjustment instructions.
