6.7.1 Adjustable 3
rd
Drum (50 series): The purpose of the adjustable 3
rd
flail tube in the 50 series de-
foliator is to be able to run the 1
st
drum higher specifically designed for crops with poor emergence
where the highest beet and lowest beet vary greatly in height. In such a situation running the defolia-
tor level and low enough to clean all beets the 1
st
drum would cut the tops off many of the higher
beets. Typical conditions do not warrant adjustment of the 3
rd
drum. If they do, adjusting the 3
rd
drum should be done in ¼ ” (.6cm) increments and directions can be found in Adjustments section
7.0.
6.8 Leveling
Two things affect a defoliator ’ s field level machine setup and field
conditions
6.8.1 Machine Setup
The first thing that impacts the defoliator field level is the actual ma-
chine level setup from side to side. This is affected by tire pressure,
machine weight and rear strut adjustment. To ensure the machine
is level, a onetime level check/setup should be performed on a flat
and level floor following the guidelines laid out in section 7.0.
6.8.2 Field Conditions
The second thing that impacts the defoliator field level are the field level conditions. This is affected
by planter and sprayer tracks left in the field. It is best to adjust the defoliator wheel locations to
avoid running on the same rows as the planter or sprayer tracks. In cases where this cannot be
avoided, one tire should be run off the tracks from the planter or sprayer and the rear struts moved
out as wide as practical to lessen the impact on machine level.
6.9 Row Finder (option):
Amity defoliators with steerable struts have the option of a hydrau-
lic row finder. The row finder helps keep the defoliator flails directly
in line with crop rows. Row finder hydraulic flows should be set to
approximate 7 GPM constant and 10 GPM override. The override
circuit flow may be adjusted up or down to adjust to desired steer-
ing response time. The row finder should be lifted when the defoliator reaches the headland before
turning and only lowered once the defoliator is back into the beet rows so the row finder lands onto
a row. Lowering too soon may cause the defoliator to miss the row and push the machine off the row
instead of keeping it on. If the row finder gets off the row use the manual override to steer back onto
the row.
