10.13.3 Header Draper Alignment
Each draper deck has one fixed roller and one
spring-loaded roller. The spring-loaded roller is
located at the same end of the deck as the draper
tensioner.
Both rollers can be aligned by adjuster rods so
that the draper tracks properly on the rollers.
CAUTION
To avoid personal injury, before servicing
machine or opening drive covers, follow
procedures in Section 10.1 PREPARATION
FOR SERVICING.
If the draper is tracking incorrectly, make the
following adjustments to the rollers:
