Reel Frown; Adjusting Reel Frown - MacDon D65 Operator's Manual

2. For Double Reel Only: Adjust center arm lift cylinder
stop (A) to change clearance at inboard ends of reels
as follows:
NOTE:
Instructions apply to double-reel headers only
and are performed from the underside of the arm.
a. Loosen nut (B).
b. Turn nut (C) counterclockwise to raise reel and
increase clearance to cutterbar, or clockwise to
lower reel and decrease clearance.
c. Tighten nut (B).

5.8.2 Reel Frown

The reel is factory-set to provide more clearance at the center of the reel than at the ends ('frown') to compensate
for reel flexing.

Adjusting Reel Frown

The frown is adjusted by repositioning the hardware connecting the reel tube arms to the reel discs.
NOTE:
Measure the frown profile before disassembling the reel for servicing so the profile can be maintained
during reassembly.
1. Position the reel over the cutterbar (between '4' and '5'
on the fore-aft position decal). This position provides
adequate clearance at all reel fore-aft positions.
2. Record the measurement at each reel disc location for
each reel tube.
