CUTTING EDIBLE BEANS: TROUBLESHOOTING
SYMPTOM PROBLEM SOLUTION
Header stripping plants-
Complete or partial plants
left behind (continued). Reel too slow. Adjust reel speed to be marginally faster than
ground speed
Tip: Look at perimeter of reel discs. they
should appear to be being driven by the
ground
- If they look like they are skidding relative to
ground, the reel is turning too slow
- If they look like they are spinning
excessively relative to ground, reel speed may
be too fast and create shattering.
Ground speed too fast. Lower ground seed
Start at 3.0 - 3.5 mph and adjust as required.
Tips:
-When cutting very light crop ground speed
may have to be reduced to allow reel to pull in
small and short plants.
-Reel speed may be increased if it does not
create excessive shattering.
Header skid shoes
adjusted too low.
Raise skid shoes to max. up position
Dirt packs on bottom of
cutterbar and raises
cutterbar off the ground.
Install plastic wear strips on bottom of
cutterbar and skid shoes.
Dirt still packing on
bottom of cutterbar with
poly wear strips on
cutterbar and raises
cutterbar off the ground.
Ground too wet. Wait until top of ground starts
to turn grey or manually clean the bottom of
cutterbar when accumulation gets
unacceptable.
Plastic wear strip for
cutterbar has been
installed over top of steel
wear plates.
Remove steel cutterbar wear plates when
installing the plastic wear strips for cutterbar.
Header not level. Level Header – see Tractor Operator’s
Manual.
Dirt builds up between
plastic cutterbar wear
strips and causes header
to cut higher off the
ground.
Reduce spacing between clips.
Knife sections worn out
and have no serrations
left causing plants to slip
out of guards and
sections.
Replace sections or complete knife.
Tip:
-Coarse serrated sections last longer when
operating in dirty conditions.
-Fine serrated sections loose their serrations
faster and will leave behind uncut plants.
Knife sections have
edges broken off.
Replace sections or complete knife if required.
