FLOW REGULATOR: Determines the rate at which
the material flows from the hopper. The highest number
setting (7) on the regulator scale indicates the largest
opening, for maximum flow of material. The lowest
number setting (1) indicates the smallest opening, for a
minimum flow of material. At (0) the disc is closed.
Note the stop pin which is chained to the flow regulator:
a. If the spreader is not equipped with the flow control
kit, the stop pin is used to stop the flow regulator
handle in the setting of the desired rate of material
flow.
b. If the spreader is equipped with the flow control kit,
the stop pin is NOT USED. The rate of material
flow is controlled by the limit switches.
IF THE SPREADER IS NOT EQUIPPED WITH THE
FLOW CONTROL KIT, THE FLOW CONTROL HAN-
DLE SHOWN IN FIG. 3 IS USED AS DESCRIBED
BELOW.

2. Using the wrench furnished, loosen the two locking
nuts on each side of the arc adjuster.
3. Insert the opposite end of the wrench into the open-
ing and turn the adjuster to the desired spreading
width.
4. Re-tighten the locking nuts.
IMPORTANT: When spreading sand, the spout arc
must be at the "–" or MIN. setting.
The table below gives some suggested spread widths and
spout arc settings for a variety of materials.
MATERIAL SPREAD WIDTH SPOUT ARC
Granulated 40 ft. (12m) – (Min)
Prilled 40 ft. (12m) + (Max)
Powdered 20 ft. (6m) (Midway)
Urea 32 ft. (10m) + (Max)
The spreader unit can be fitted with two different spouts.
The smaller metal spout (packed with the spreader
mounting kit) is recommended for spreading sand. The
longer nylon spout is recommended for spreading fertil-
izer.
SPREADER CALIBRATION
To calibrate the TORO spreader you must determine the
desired rate of flow for the material being applied (in
pounds per acre), as specified by the material's manufac-
turer.
To achieve this application rate, first establish the fol-
lowing:
1. The spread width, for the material being applied.
NOTE: This width will vary depending on the den-
sity of the material and the spout arc setting.
2. The flow rate of material from the hopper, in Kg.
per acre. This will depend on the particle size of
the material and the position of the flow regulator
setting.

3. The desired working speed of the Workman®vehi-
cle, in miles per hour.
OPTIONAL FLOW CONTROL
(MODEL NO. 41403)
The two limit switches control the length of the actua-
tor's extension or retraction and must be adjusted to
match the actuator's action to the flow regulator.
NOTE: After positioning the limit switches for a full
“OPEN” and a full “CLOSE” disc opening as described
in the flow control set-up instructions, the front limit
switch should not need further adjustment. However, the
rear limit switch must be readjusted to achieve any of the
other rate of flow settings indicated on the regulator
scale, as follows:
Fig. 6

4. Flow regulator scale
1. Use the toggle switch on the control box to extend
or retract the actuator until the front edge of the
flow regulator handle is at the selected number on
the regulator scale.
