RULES FOR SAFE OPERATION
Any power equipment can cause injury if operated improperly or if the user does not understand how to operate
the equipment. Exercise caution at all times when operating equipment.
• Read the towing vehicle owners manual and tow-
ing vehicle safety rules. Know how to operate your
tractor before using the broadcast spreader attachment.
• Read the chemical label instructions and cautions
for handling and applying the chemicals purchased
for spreading.
• Wear eye and hand protection when handling and
when applying lawn or garden chemicals.
• Never operate tractor and spreader attachment
without wearing substantial footwear, and do not
allow anyone to ride or sit on spreader attachment
frame.
• Never allow children to operate the tractor or
spreader attachment, and do not allow adults to
operate without proper instructions.
LOOK FOR THIS SYMBOL TO POINT OUT IMPORTANT SAFETY PRECAUTIONS. IT
MEANS -- ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED.
CARTON CONTENTS
LOOSE PARTS IN CARTON
• Always begin with the transmission in first (low)
gear and with the engine at low speed, and gradually increase speed as conditions permit. Maximum towing speed - 10 M.P.H.
• When towing broadcast spreader do not drive too
close to a creek or ditch and be alert for holes and
other hazards which could cause you to loose
control of the broadcast spreader and tractor.

OPERATION
HOW TO USE YOUR SPREADER
SETTING THE FLOW CONTROL
(Refer to figure 12 on page 7.)
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.
3. Pull the flow control arm against the adjustable stop for
the on position and toward the hopper for the off
position.
USING YOUR SPREADER
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
page and to the instructions on the fertilizer bag to
select 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. Always start the tractor in motion before opening clo-
sure plate.
7. Always shut the closure plate before turning or stop-
ping the tractor.
8. If fertilizer is accidentally deposited too heavily in a
small 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 13. 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.
FIGURE 13
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.

MAINTENANCE
SERVICE AND ADJUSTMENTS
CHECK FOR LOOSE FASTENERS
1. Before each use make a thorough visual check of the
sreader for any bolts and nuts which may have
loosened. Retighten any loose bolts and nuts.
CHECK FOR WORN OF DAMAGED PARTS
2. Check for worn or damaged parts before each use.
Repair or replace parts if necessary.
CHECK TIRE INFLATION
3. Check if tires are adequately inflated before each use.
Do not inflate beyond maximum recommended pressure.
CAUTION: DO NOT inflate tires beyond the maximum recommended pressure printed on side of tire.
CLEANING
4. Rinse inside of hopper and exterior of spreader and dry
off before storing.
LUBRICATE (See figure 14.)
5. Lightly apply automotive grease as needed to the
sprocket and gear.
6. Oil the nylon bushings on the vertical sprocket shaft
and on the axle at least once a year, or more often as
needed.
7. Oil right hand (idler) wheel bearing at least once a year
or more often as needed.
1. If the axle, slotted gear and sprocket assembly is
disassembled, mark down the positions of the parts as
they are removed. The drive wheel and sprocket
positions in relation to the slotted gear determine which
direction the spreader plate will spin. Be sure to reassemble them in their original positions. (Refer to figure
4 on page 5.) Use shim washers (Ref. no. 21 on pages
10 and 11) as needed for minimum backlash. Add
grease to gear and sprocket.
2. If the agitator wire becomes damaged or worn it can be
replaced. Loosen the 3/8" hex nut on top of sprocket
shaft until agitator wire is free. Remove old agitator
wire from hole in agitator sleeve and replace with new
agitator wire. Position agitator wire so that sprocket
shaft turns freely, then tighten 3/8" hex nut on top of
sprocket shaft. See figure 15.
