How To useYour sPreaDer  
seTTInG THe Flow ConTrol  
(Refer to figure 13 on page 7.)  
REFER  
TO  
CHARTS  
1. Loosen the nylon wing nut, set the adjustable stop to  
the desired flow rate setting and retighten the wing nut.  
The higher the setting number, the wider the opening  
in the bottom of the hopper.  
2. Refer to the application chart on page 8 and to the  
instructions on the fertilizer bag to select the proper  
flow rate setting.  
OVERLAP  
3. Pull the flow control arm against the adjustable stop  
for the on position and toward the hopper for the off  
position.  
usInGYour sPreaDer  
FIGure 14  
We do not recommend the use of any powdered lawn  
chemicals, due to difficulty in obtaining a satisfactory or  
consistent broadcast pattern.  
1. Determine approximate square footage of area to be  
covered and estimate amount of material required.  
2. Before filling the hopper make sure the flow control arm  
is in the off position and the closure plate is shut.  
3. Break up any lumpy fertilizer as you fill the hopper.  
4. Set the adjustable stop with the flow control arm still in  
the off position. Refer to the application chart on this  
pageandtotheinstructionsonthefertilizerbagtoselect  
the proper flow rate setting.  
5. The application chart is calculated for light to heavy  
application at a vehicle speed of 3 mph, or 100 ft. in 23  
seconds.A variation in speed will require an adjustment  
of the flow rate to maintain the same coverage. The  
faster you drive, the wider the broadcast width.  
6. Alwaysstartthetractorinmotionbeforeopeningclosure  
plate.  
7. Always shut the closure plate before turning or stopping  
the tractor.  
8. Iffertilizerisaccidentallydepositedtooheavilyinasmall  
area, soak the area thoroughly with a garden hose or  
sprinkler to prevent burning of the lawn.  
9. To insure uniform coverage, make each pass so that the  
broadcast pattern slightly overlaps the pattern from the  
previous pass as shown in figure 14. The approximate  
broadcast widths for different materials are shown in  
the application chart on this page.  
10. When broadcasting weed control fertilizers, make sure  
the broadcast pattern does not hit evergreen trees,  
flowers or shrubs.  
11. Heavy moisture conditions may require a cover over the  
hopper to keep contents dry. The vinyl cover (available  
as an accessory) acts as a wind and moisture shield,  
but should not be used as a rain cover. Refer to the  
parts list on page 11.  
ImPorTanT: Application rates shown in the chart are  
affected by humidity and by the moisture content of  
the material (granular and pellet). Some minor setting  
adjustments may be necessary to compensate for this  
condition.

3. Spin the drive wheel and note how freely it spins and  
how much noise the slotted gear makes.  
4. To free up the wheel and gear, tap gently on the front
