MAINTENANCE/SERVICE
AUGER AND AUGER DRIVE
Auger Position
The auger position has been factory set and
should not normally require adjustment. For nearly
all conditions, the auger performs best when set
as close as possible to the stripper bars without
rubbing. This is especially important in grass and
other crops which have a tendency to wrap.
Component wear may cause clearances to
become excessive, resulting in feeding problems
and uneven windrows.
NOTE: In heavier crops it may be necessary to
remove the front stripper for smoother crop flow
across the auger.
Should adjustment be required:
1. Loosen nut (A), left side, securing auger drive
chain idler sprocket.
2. Loosen reel drive belt and chain. See page 52
for adjustment details
3. Loosen bolts (B), four per side.
4. To adjust auger fore-aft:
a. Loosen jam nut on bolt (C), both sides.
b. Turn adjuster nuts to move auger fore or aft to
desired position.
c. Tighten jam nut on bolt (C).
5. To adjust auger vertical position:
a. Loosen jam nuts (D), two per side.
b. Turn push bolts (E), two per side, to lower or
raise auger.
c. Tighten jam nuts (D).
NOTE: The auger should clear the stripper bars on the
auger pan by approximately 1/32” – 5/32” (1 - 4 mm).
See next page for stripper adjustment.
6. Tighten bolts (B) to secure the position.
7. Adjust tension of auger drive chain, reel drive
belt, and reel drive chain. Tighten hardware.
