Spreader Constant (under Meter Cal): __________ 7
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.
Meter Cal shows 0 on Dry when console has not been set.
Hold Meter Cal key down until it shows SPREADER CONSTANT

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.
