CUTTING EDIBLE BEANS: TROUBLESHOOTING
SYMPTOM PROBLEM SOLUTION
Cutterbar pushing too much
dirt in certain locations for
length of field. Tire tracks or row crop
ridges caused by seeding
or spraying operations.
Rolling land along length
of field due to cultivating. Cut at angle to ridges or crop rows to allow
knife and guards to clean out better. When
cutting in line with tracks or ridges the same
guards and sections have to cut in dirt for the
whole length of the field. Cutting at an angle
shifts these ridges through all guards and
prevents pushing dirt.
Cut at 90° to undulations, provided knife floats
across without digging in.
Cutterbar fills up with dirt. Excessive gap between
top of front of draper and
cutterbar. Adjust front deck hooks to obtain proper
clearance between cutterbar and draper. If
cutterbar still fills up with dirt, raise header to
max. up position at each end of field or as
required and shift decks back and forth to help
clean out cutterbar. Most dirt will fall out
without manually having to clean drapers.
Plant vines pinched
between top of draper and
cutterbar. Cutterbar has filled up
with trash in excessively
dirty conditions with
draper to cutterbar gap
properly adjusted. Raise header to max up position at each end
of field or as required and shift decks back and
forth to help clean out cutterbar. Most dirt will
fall out without manually having to clean
drapers.
Shifting of decks with
header raised up does not
clean out cutterbar debris.
Dirt and trash is too wet to slide out of
cutterbar cavity on its own. Manually remove
debris from cutterbar cavity immediately when
noticing material between draper and cutterbar
or this will damage drapers.
Reel carries over odd plants
in same location. Reel fingers (steel) bent
and hook plants out of the
crop flow on drapers. Straighten fingers (steel).
Dirt accumulation on end
of fingers do not let plants
slide off fingers over
drapers.
Reel too low relative to the ground.
-Adjust reel fore and aft location to move
fingers out of the ground.
Reel carries over excessive
amounts of plants or wads. Too much accumulation
of crop on drapers (up to
height of reel center tube) Speed up drapers to thin out amount of
material on drapers. This is aggravated when
double swathing. Higher draper speeds have
to be used when double swathing.
Finger pitch too retarded. Increase finger pitch to move finger flip-over
point out of the crop flow. Reducing the finger
pitch takes the fingers that are starting to flip
over lower into crop flow.
Excessive amount of
vines and plants or weeds
cause reel to wrap up.
Raise reel a slight amount when getting into a
patch of viney weeds or green viney crop.
Excessive guard breakage Header float too heavy. Adjust float to make header lighter.
Excessive amount of
rocks in field.
Try using stub guards if using regular guards.
Tip: Experiment with a few guards on a section
of cutterbar to compare the performance of the
two different styles of guards.
