CUTTING EDIBLE BEANS: TROUBLESHOOTING
SYMPTOM PROBLEM SOLUTION
CUTTING EDIBLE BEANS
Header stripping plants-
Complete or partial plants
left behind
Header being carried off
ground
Lower header to ground and run on skid shoes
and/or cutterbar
Float set too light - rides
on high spots and does
not get back down soon
enough
Set float for: 100-150 lbs. - dry ground
50-100 lbs. - wet ground
Float should be lighter for light soils and
heavier for hard heavy soil areas
Reel being operated too
high
Fully retract reel cylinders
Operate reel at max. down position in all
conditions unless excessive wrapping occurs
in a green matted viney crop.
Reel too high with
cylinders fully retracted
Adjust reel height with cylinders fully retracted
to obtain minimum clearance to knife.
Important - maintain adequate clearance to
prevent finger from getting in knife.
Finger pitch not
aggressive enough
Adjust finger pitch:
Start with 1-2 notches more aggressive than
mid-position
-readjust reel fore and aft if necessary
-readjust reel clearance with cylinders fully
retracted
Reel too far back on reel
support arms
Move reel forward until the fingertips skim the
soil surface with header on ground and center
link properly adjusted.
Start in hole #6 to #8 from front of support arm
Re-adjust reel height with cylinders retracted if
necessary
Check finger clearance to ground
- Adjusting reel forward gets reel closer to
ground and back will move reel away from
ground
Header angle too shallow Lengthen center link to max. length to start
with. Decrease center link length if header
pushes too much dirt.
Tip: Use variable header angle feature at
bottom end of header lift stroke to vary header
angle on the go.
-Once header touches the ground the header
angle will be increased if the header lift
cylinders are further retracted.
-With header on the ground the header will get
shallower as the lift function is actuated until
the header is lifted off ground.
- Header angle can be varied up to 4
degrees by fully retracting lift cylinders
from when header touches the ground.
Note: If frequent adjustment of the center link
is necessary, a hydraulic center link is
available.
