JDOffice 1.2
The boxes start and end at the location of the combine
position receiver - not at the header as the operator
assumed. The recorded flags are off approximately 12-14
feet from where the operator thought he was flagging.
You can compensate for this offset while driving the
combine. Instead of turning the flag on and off when the
header reaches the designated area, you can turn the flags
on and off when the position receiver on the equipment cab
is “on top” of the area.
Reasons to Use Flags
Reason 1 - Identify a Condition: As the operator is driving the combine through the field,
large areas of Canadian Thistle are present. Using the GreenStar Display and the flags
pick list, the operator can easily flag the affected areas.
After unloading the PC Card to JDOffice, the summary reports and maps will clearly show
the effects of the Canadian Thistle on the yield compared to the rest of the field. Some
quick math will then tell you if the cost of treating the condition will be less than the loss of
revenues from reduced yield.
Reason 2 - Preplanned Test: You may have a test plot and want to compare two different
test rates. For example, you want to apply 150 pounds of nitrogen per acre and 180
pounds of nitrogen per acre to a different part of the field. At harvest time, you want to
compare the final yield results between the two areas.
After unloading the PC Card to JDOffice, the summary reports and maps will compare the
yield results in the two test areas. This will allow you to quantify the impact of reducing the
nitrogen application rate from 180 to 150 pounds per acre.
