Spreader System

Spreader Calibration/Layout
The Spreader Motor Control determines the speed
of the impeller in the front on the machine. Your
machine is capable of varying its spread pattern from
3 – 25 feet with this control. Being hydraulically
driven, the spread pattern is independent of the
ground speed.
The hopper control cable opens and closes the door
inside the base of the hopper. The maximum size of
the opening will be determined by the rate adjustment
on the Hopper Rate Dial. This will set your rate gate
linkage bar to limit and stop the rate the door can
open.

The Diffuser adjustment allows the user to adjust the
intensity of the spread pattern. A small pull shifts
the product placement on the impeller either to the
edge of the impeller or the middle of the impeller.
This in turn shifts the spread pattern heavier to the
left (placing product to the edge of the impeller) or

heavier to the right (placing product to the middle
of the impeller).
Your machine is equipped with a 120 lb. Spyker
model spreader. The hydraulic spreader motor with
the spreader motor control has the ability to vary
spread widths from 3 to 25 feet. This depends on
volume/density, particle size and rate of travel, and
weather conditions. The pattern can be increased or
decreased while spreading depending on needs. A
typical pattern is to overlap fertilizer pattern back to
the tire tracks and the spray pattern boom to boom.
This feathers material at the outer edges, eliminating
sharp "edge to spread" lines which cause stripes and
streaks.
Determine a dial setting on the low side. If setting
is too low, cover the area more than one time. A
higher setting can be used when a proven dial setting
is established. Travel at a constant speed.

Remember- Published dial settings are approximate
only. Open the hopper door after the spreader is
turned on at operating speed.
