Number must match correct gate setting. This # is based
on bed chain width, gate height, and pulses per revolution
of the rear roller for the spreader being used. There are
many choices. Chart below shows a few options.

Never exceed 6 inches
in gate height for best fertilizer spread
pattern. (Spreader constant for various gate heights on a Newton Crouch Spreader should
be verified with a catch test, with verified data entered [density, swath, LBS/AC, etc.]). The
above LBS/AC varies with SPEED, DENSITY, SWATH, etc.
The gate height settings should be checked reading from
the floor of unit
to bottom of gate.
You CANNOT enter a decimal
place in this number
If setting already entered and you are moving from a different setting to METER CAL, screen shows PRODUCT
