Variable Rate Kit
The variable rate actuator kit places the material rate
under the control of the seed monitor. This allows conve-
nient rate setting and adjustment from the tractor cab, as
well as GPS control of rates. The manual adjuster crank
is de-coupled, and left in place.
Installation is described in the 166-263M manual
included with the kit.
See “Variable Rate (Servo) Calibration” on page 78.

High Rate Flute Sets
The standard NTA607/2007HD Drill meter has two fluted
wheels (“stars”) and two filler rings in each meter com-
partment.
If your seeding rates need to be higher than those listed
in the Seed Rate manual, these accessories replace the
existing shaft assembly with one having more stars. See
“Changing Meter Flutes” on page 163 for installation
instructions.
Replacing the standard 2-star shafts with 3-star
shafts increases the seeding rate by approximately
50% (150% of standard rate). Replacing standard 2-star
shafts with 4-star shafts
increases the seeding rate by
approximately double (200% of standard rate).
The kit required depends on the number of stars desired.
Order one kit per meter (two per drill if changing both
meters)
