CUTTING EDIBLE BEANS: TROUBLESHOOTING
SYMPTOM PROBLEM SOLUTION
Cutterbar pushing too much
trash and dirt (continued). Improper support for
header. Install center skid shoes on header. This
reduces the ground pressure and reduces the
possibility of pushing excessive amounts of dirt.
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.
