REFER
TO
CHARTS
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 adjust-
ment 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 approxi-
mate 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 mois-
ture shield, but should not be used as a rain cover
Refer to the parts list on page 11
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
OPERATION

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 pres-
sure
FIGURE 14
1 Rinse inside of hopper and exterior of spreader and dry
off before storing
2 Store in a clean, dry area
CAUTION: DO NOT inflate tires be-
yond the maximum recommended pres-
sure 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

STORAGE
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 reas-
semble 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
