run the switch harness down through the 

switch harness bracket and snap into bracket. 

See Figure 2-17.

9. 

Connect the switch harness to the motor wire. 

See Figure 2-18.

10. 

Connect the battery harness clips to the 

battery terminals. Remove the plastic cover, if 

present from the positive battery terminal and 

connect the red wire to the positive terminal, 

then connect the black wire to the negative 

terminal. See Figure 2-19.

Allow a little slack in the wire, but secure it to 

the hopper frame with tie straps.

NOTE: 

Tie straps are not included with this kit.

Coverage Calculator

Use the chart and/or formula at the bottom of 

this page to determine proper tractor speed for 

spreading coverage.

NOTE: 

Aperture opening is approximate. 

Aperture opening and tractor speed should 

be adjusted as needed to achieve coverage 

suggested by the material manufacturer. See 

Figure 2-20.

NOTE: 

Conduct this test procedure on a flat 

level surface.

1. 

Record the desired coverage. For example: 

20 lb per 2,000 sq. ft. 

2. 

Fill the hopper at least half full with a 

premeasured amount of material. Record the 

amount of material.

3. 

Turn on the spreader and open the feed gate 

briefly (one or two seconds). Turn off the 

spreader. With a tape measurer, measure the 

width of the material spread on the ground 

from one side to the other, and record the 

spread width (diameter).

4. 

Use a stopwatch to record how long it takes all 

the material measured out for this test to flow 

out of the hopper.

NOTE: 

Turn ON the spreader when taking 

this measurement. Mounding material on the 

spinner may slow down material flow.

5. 

Use measurements in the formula listed below 

to calculate drive speed needed to accurately 

fulfill your coverage and material amount 

requirements.

6. 

If your calculations result in a speed faster than 

the mower is capable of driving, divide your 

drive speed in half and use a half open gate 

setting.

a. 

Adjust the control handle until the 

opening is about .78”.

b. 

Loosen, position and retighten the 

wingnut on your adjustable stop so 

that the control handle does not move 

out of position.
