Setting the Rolling Harrow and Reel
Refer to Figure 31
27. 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.
28. The reel down pressure may be adjusted by removing
the pin and then either pushing the handle forward
to increase the spring pressure or by pulling the handle
backwards to decrease the spring pressure
. When the
desired amount of spring pressure is set, re-insert the
pin
. Note: It is recommended to run little or no down
pressure in wet or sticky field conditions.
Refer to Figure 32
29. 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.
