MAINTENANCE/SERVICE
DRAPERS AND DRAPER DRIVE (continued)
Draper Tension
Draper tension is adjusted with spring assemblies
at each end of the idler roller. Tension should be
adjusted just tight enough to prevent slippage.
Also, by varying the front and rear spring settings
with respect to each other, the draper can be
adjusted to track closer to, or further from the
cutterbar. See "Draper Tracking" in this section.
To adjust:
1. Release draper tension by using hand or foot to
move lever (A) over-center, toward end of
header.
CAUTION: Spring loaded over-center
action causes handle to kick back
when tension is released. To avoid
possible injury, do not hold lever when
releasing tension.
2. Springs are located at each end of idler roller.
3. To increase tension, slide U-shaped channel
(B) to compress spring (C). Repeat on opposite
end of roller
4. To decrease tension, push washer (D) against
channel spring (E) to release grip on rod, then
slide channel (B) away from spring (C). Repeat
on opposite end of roller.
5. Apply draper tension by rotating lever (A)
toward center of draper.
NOTE:
If drapers must be excessively tightened to
prevent slippage, a drive roller lagging kit is
available from your dealer.
