MAINTENANCE/SERVICE
DRAPERS AND DRAPER DRIVE
Draper Care
IMPORTANT: The investment in time to be sure
drapers are properly adjusted and running true will
greatly increase draper life. Be sure that:
1. Draper tension is released after the day's
operation.
2. Draper tension is set just high enough to
prevent slipping.
3. Draper rollers are adjusted so draper edge runs
parallel to, and just touches cutterbar at cutting
height
Draper Tracking
IMPORTANT: When first checking draper tracking,
operate PTO with tractor engine at idle. Drapers
can then be stopped quickly to prevent damage
caused by excessive misalignment.
To align drapers:
1. If draper edge is further from cutterbar (B) at
idler roller than at drive roller (C), move front of
drive roller (C) away from draper (A).
2. If draper edge is closer to cutterbar (B) at idler
roller than at drive roller (C), move front of drive
roller (C) toward draper (A).
