MAINTENANCE AND SERVICING
Adjusting Reel Frown
The frown is adjusted by repositioning the hardware connecting the reel finger tube arms to the reel discs.
To adjust the reel frown, follow these steps:
NOTE:
The frown profile should be measured prior to reel disassembly for servicing so that the profile can be
maintained after reassembly.
1. Position the reel over the cutterbar (between ‘4’ and
‘5’ on the gauge).
This position provides adequate
clearance at all reel fore-aft positions.
2. Record a measurement at each reel disc location for
each reel tube.
Figure 6.196: Arm Decal
3. Adjust the profile as follows: Start with the reel disc set
closest to center of header and proceed to the ends.
a. Remove bolts (A).
b. Loosen bolt (B) and adjust arm (C) until desired
measurement is obtained between reel tube
and cutterbar.
NOTE:
Allow the reel tubes to find a natural
curve
and position the hardware
appropriately.
c. Reinstall bolts (A) in aligned holes and tighten.
