How To use Your sPreaDer
seTTInG THe Flow ConTrol
(Refer to figure 13 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.

TO
CHARTS
OVERLAP
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 closure plate.
7. Always shut the closure plate before turning or stopping 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 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.

FIGure 14
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
1.
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
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.
serVICe anD aDJusTmenTs
rePlaCInG sloTTeD Gear
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.
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 15.)
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.
IF THe sPreaDer loCKs uP
1. Turn the spreader over so that the wheels are off the ground.
2. 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.
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 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.
5. Spin the drive wheel after each adjustment to see if it spins more freely and if the gear noise is reduced.
6. Continue making slight adjustments until you find the position where the drive wheel spins most freely and the gear makes the least noise.
7. Secure the shaft support plate in this position by retightening all three nuts that you loosened.
