Setting the Rolling Harrow and Reel
Refer to Figure 16
35. The rolling harrow and reel attachment is a very ver-
satile leveling attachment and requires very little adjust-
ment. The rolling harrow sections come preset at 22
degrees and should not need to be modified. In some
severe conditions at high speeds, some windrowing may
occur and the gang angle may need to be reduced
slightly. When adjusting this, be careful to maintain ade-
quate clearance between sections in the field position as
to not cause damage to the units.
36. The reel down pressure may be adjusted by loosening
the jam nut and then either increasing or decreasing
the spring pressure . When the desired amount of
spring pressure is set, re-tighten the jam nut . Note: It
is recommended to run little or no down pressure in wet
or sticky field conditions.
Refer to Figure 18
37. The bars on the reels are angled forward
and should be
installed as such on the machine. In some conditions in
which a firming of the soil is more desirable than breaking
up clods then these reels can be mounted in reverse
.
This does however increase the chance of causing dam-
age to the bars in rocky soil.
Be sure reels are installed with twisted bars oriented forward as
shown. Mounting in reverse can damage reel in rocky soil.
