Losses
Where are the losses coming from?
To work out what is coming from the
rotors engage the chaff spreader and
carry out a check behind the combine,
count the grains on the floor.
To check the losses from the sieves
disengage the chaff spreader and
engage the chopper and spread this
as wide as possible and then count the
grains.
Take into account what the grains look
like, unthreshed heads etc. Now make
the corresponding adjustments.
After adjusting the combine make
sure that the monitors also reflect
what you will accept as a loss.
Adjust monitor setting so that the
blue area is approaching the limit
lines, the black line.
TIP. The easiest way to check
for losses is in the swath with
the chaff spreader and chopper
disengaged.
TIP. Count the number of grains
within your hand print. 1 grain
per foot of cutterbar is close to
1% loss.
