OPERATION

HOW TO USE YOUR SPIKER/SPREADER

1. Refer to the instruction label on the material package and to the instruction decal on your spreader to help determine the proper spreader  setting and application rate. Also see the Setting Chart on this page for a general range of settings for commonly used materials.
2. Determine the approximate square footage of the area to be covered and estimate the amount of fertilizer or seed required.
3. Move the spreader to the area where application is to begin.
4. Loosen the plastic wing nut and move it to the desired setting. Retighten the nut. See figure 25.
5. Make sure the flow control lever is in the “OFF” position. Fill the hopper, and break up any lumps.
6. Lower the aerator spikes to the operating position.
7. Start the spreader in motion and then move the flow control lever to the “ON” position (against the plastic wing nut) as you travel across your lawn. The maximum towing speed is 3 m.p.h.
8. Do not make sharp turns with spikes in the ground.
9. Raise aerator spikes to transport position when crossing over concrete or other hard surfaces.
10. Do not aerate if the ground is extremely hard or dry. If ground is too dry, sprinkle or water for one to two hours prior to use.
11. Do not aerate if the ground is too wet.

IMPORTANT: Always place flow control lever in the “OFF” position to prevent excess fertilizer from being released when filling the spreader and when stopping or turning.

SETTING CHART

3 M.P.H. is equivalent to traveling 100 feet in 23 seconds.

APPLICATION TIPS

1. To help prevent granular material from compacting and clogging the hopper, avoid unnecessary towing when the hopper flow plates are closed.
2. Reduce the flow setting for speeds slower than 3 M.P.H.
3. To avoid misses or striping, overlap the previous wheel tracks by approximately 5″ to 6″.
4. For easiest application, first apply material across both ends of the area. Two or three passes on each end are sufficient. Then apply material back and forth as shown. Use the end areas for turning around, shutting off the spreader as you enter the end areas and turning the spreader on again as your leave the end areas for your next pass. See figure 26.
5. If lawn is odd shaped, spread a border around the edges and then spread between the border.
6. Be careful when spreading around ornamental plants because weed control chemicals can damage these plants.

Spike points are sharp. Exercise caution when handling or working near spike disks.

MAINTENANCE

1. Check nuts and bolts for tightness before each use.
2. Always empty hopper after each use, storing leftover material in its original bag.
3. Wash and dry thoroughly after each use.
4. Apply a light coat of oil on exposed metal parts to help prevent rust.
5. At least once a year, apply a few drops of oil to wheels, plastic bearings in spike disks, at ends of aerator shaft, and at ends of hopper shaft.
6. Clean and oil drive chain once a year.
