The most flexible way to determine rate setting is to use
the flow rate calculator on the CDS-John Blue web site:
www.cds-johnblue.com/flow-rate-calculator.shtml
It provides precise pump settings at arbitrary rates and in
all units of measure.
The four tables following provide supporting data needed
with the web calculator. This data is valid for both drill-
mounted pumps, and pumps on PFC1600 or PFC2000
carts. Both Great Plains systems use the same NGP-
6055K pump.
Some notes:
• The loaded radius values are the actual effective
radius of the ground drive or contact drive wheels,
based on field results.
• Swath width is slightly higher on standard down flex
models of NTA607/2007/HD.
• To ease data entry, the tables list the net effective ratio
(“As one stage”) of all ground drive stages.
