Open and Close: The material flow is shut off by moving 
Control Lever to the left and locking into "V" notch on 
calibration plate.

Flow Setting: To set the flow rate, put the Control Lever in 
the shut-off position (in "V" notch). Determine your required 
number setting as described below. Loosen the nylon wing 
nut and slide to the desired number setting and retighten the 
wing nut. Release the control strap and it will open to the 
pre-set position.

NOTE: Fertilizer application rates as described are affected 
by humidity and the moisture content of the material; 
therefore, minor setting adjustments may be necessary to 
compensate for these conditions.

To determine the required setting for materials not listed on 

chart, proceed as follows:

 

Determine from material bag, the amount of material to be 

spread over a designated area. Example: "The contents of 

this bag (25 lbs.) will cover 5000 square feet."

Determine the amount of material required to cover 100 

square feet as follows:

 

-Add two zeros to bag weight. Example: 2500 

 

-Divide this number by the number of square feet  

 

 on the bag.Example: 2500 divided by 5000 = .5   

 

 pounds of  material for 100 square feet. NOTE: To  

 

 convert this weight to ounces, simply multiply by 16  

 

 (16 oz./lb) Example: .5 lb. x 16 = 8 oz.

Determine approximate Flow Control Setting by using chart 

below showing type of material to spread.

Measure off a distance of 40 feet in your yard. This is the 

distance your 30" spreader must travel in order to cover 100 

square feet.(2.5 ft. (30") x 40 ft. = 100 sq ft.) For 40" 

spreader measure off a distnce of 30 feet in your yard, the 

distance to cover 100 square feet.

(3.33 ft. (40") x 30 ft. = 100 sq ft.) 

Set the spreader flow control at the approximate flow control 

setting.

Place 5 pounds of material in the Hopper. Weigh the 

material before and after spreading 100 square feet to 

determine amount of material used.

Move unit to measure area, lower aerator tines, open Flow 

Control Lever. Drive the 40 ft. course, stop unit and close 

Flow Control Lever.

Remove and weigh remaining material. Subtract this weight 

from 5 pounds to determine material used: If too much 

material is used: Set Flow Control ONE number LOWER 

and try again. If too little material is used: Set Flow Control 

ONE number HIGHER and try again.

After determining proper setting always record the type of 
material and the setting for future use.

Should rust appear on any other part of your Aerator-

Spreader, sand lightly to remove rust and coat lightly with 

enamel.

Apply a drop of lubricating oil to each nylon bearing (aerator 

tine shaft, agitator shaft, and wheels) before each use.

Be sure to remove all unused fertilizers from hopper 

immediately after use and clean with water.

To prevent rust in aerator tines, apply a light coat of oil on 

the working areas of tines after each use.

After each use, service unit as described and store in a dry 

area, shielding tines to avoid injury.
