* For most vehicles, you can keep the assembled hitch

extension bracket in its default position shown in

figure 10. Attach the spreader hitch to your vehicle

hitch. Check for interference with the spreader directly

behind and out to both sides of the vehicle. Lift the
spreader at each position to make sure there is no

interference with the spreader's flow control, if there
is interference with the rear of the vehicle, assemble

the hitch extension bracket as shown at the bottom
of figure 10. Tighten bolts and nuts when finished.

HOW TO USE YOUR SPREADER

SETTING THE FLOW CONTROL
(Refer to figure 8 on page 6.)

• 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.
Refer to the application chart on this page and to the
instructions on the fertilizer bag to select the proper
flow rate setting.
Pull the flow control arm against the adjustable stop
for the on position and toward the hopper for the off
position.

THE FREE WHEELING FEATURE
(Refer to figure 4 on page 5.)

The spreader is equipped with a removable pin in the
left (drive) wheel. Remove the pin to disengage the drive
wheel so that the axle, gears and spreader plate do not
rotate. With the drive wheel disengaged, the spreader
may be towed at speeds up to 20 mph. If the drive wheel
is engaged do not exceed 6 mph.

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.

To insure uniform coverage, make each pass so that
the broadcast pattern slightly overlaps the pattern
from the previous pass as shown in figure 11.The
approximate broadcast widths for different materials
are shown in the application chart on this page.
When broadcasting weed control fertilizers, make
sure the broadcast pattern does not hit evergreen

trees, flowers or shrubs.

Heavy moisture conditions may require a cover over

the hopper to keep contents dry. The vinyl cover acts
as a wind and moisture shield, but should not be

used as a rain cover.

FIGURE 11

Determine approximate square footage of area to be
covered and estimate amount of material required.
Before filling the hopper make sure the flow control
arm is in the off position and the closure plate is shut.
Break up any lumpy fertilizer as you fill the hopper.
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.
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.
Make sure the drive pin is installed in the axle before

starting the spreader.
Always start the tractor in motion before opening
closure plate.
Always shut the closure plate before turning or
stopping the tractor.
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.

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.

CHECK FOR LOOSE FASTENERS

• Before each use make a thorough visual check of
the spreader for any bolts and nuts which may have
loosened. Retighten any loose bolts and nuts.

CHECK FOR WORN OF DAMAGED PARTS

Check for worn or damaged parts before each use.
Repair or replace parts if necessary.

CHECK TIRE INFLATION

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.

LUBRICATE (See figure 12)

Lightly apply automotive grease as needed to the
sprocket and gear.
Oil the nylon bushings on the vertical sprocket shaft
and on the axle at least once a year, or more often as

needed.
Oil right hand (idler) wheel bearing at least once a

year or more often as needed.

. OIL

CLEANING

Rinse inside of hopper and exterior of spreader and
dry off before storing.

REPLACING SLOTTED GEAR

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.

LOCKED UP SPREADER

Turn the spreader over so that the wheels are off the
ground.
Loosen all three nuts on the shaft support plate just
enough so that the bolts can be turned easily with a
wrench but cannot be turned by hand.
Spin the drive wheel and note how freely it spins and
how much noise the slotted gear makes.
To free up the wheel and gear, tap gently on the front
or rear edge of the shaft support plate to move it
slightly forward or backward. You can also tap at the
corners of the plate to angle it slightly.
Spin the drive wheel after each adjustment to see if it
spins more freely and if the gear noise is reduced.

OIL

GREASE

FIGURE 12

SLOTTED GEAR

SHAFT SUPPORT PLATE

FIGURE 13

Continue making slight adjustments until you find the
position where the drive wheel spins most freely and
the gear makes the least noise.

* Secure the shaft support plate in this position by

retightening all three nuts that you loosened.
