Injectors - 22” Row Spacing
NOTES:
•
The values highlighted in green indicate pressures that are in the optimal pressure range of 20 - 50 psi. The row spacing is 22 inches.
•
Density or viscosity of the liquid can effect operating range.
•
A displayed pressure higher than the calculated pressure may be due to a pressure drop in the fertilizer hoses.
•
With #10 on the center, use #15 for one and a half rate outside, (35 knife).
•
With #15 on the center, use #8 for half rate outside, (37 knife), and #20 for one and a half rate outside, (35 knife).
•
With #20 on the center, use #10 for half rate outside, (37 knife), and #30 for one and a half rate outside, (35 knife).
•
With #30 on the center, use #15 for half rate outside, (37 knife), and #40 for
one and a third
rate outside, (35 knife).
•
With #40 on the center, use #20 for half rate outside, (37 knife), and #60 for one and a half rate outside, (35 knife).
For replacement injectors, see “Coulter Injector Assembly” in the Parts Manual.
