Application Calibration Rates
Calibration suggestions are based on known basic standards of use. Each operator MUST calibrate the machine to
his/her condition of use.
Operator ground speed, engine rpm, spray system pressure level, spread application pass width, terrain traveled,
ground moisture, and wind conditions affect the rate of application for both granular and liquid applications.
All spreaders must be calibrated to real use conditions. The recommended method of calibration fine tuning is to use
the products over a measured area and determine the actual rate of application.
Granular:
With all factory settings in place, the granular scale for application will deliver roughly the number of pounds product
(215-240 SGN) per thousand square feet as displayed on the rate scale.
To Verify Your Use Rate:
Measure 1000 square feet and determine the rate of application upon use. <OR> With a known quantity of product
(50 lbs.),apply over a flat turf area and measure the total square feet covered with the full amount of product.
Calculate your rate of application and adjust accordingly.
Liquid:
With all factory settings in place, the liquid rate of application will remain roughly 32 fluid ounces per 1000 square feet
of turf grass area.
To Verify Your Use Rate:
Capture the liquid from the nozzle for a one-minute period of time. Then operate your machine in a straight line under
your conditions over a one-minute period of time. This will provide the known total liquid coverage rate of application
for your machine.
Average Your Rates:
Measure the area treated by your machine using known quantities of both liquid material sprayed and granular
material applied. Average this calculation over various areas. Or, check your use rate after several lawns or areas are
treated throughout the day. This will ensure that the applicator knows the rates of application used throughout the day
and can make the fine turned adjustments as needed.
EVERY OPERATOR APPLIES PRODUCT DIFFERENTLY. MAKE SURE THE MACHINE OPERATOR VERIFIES
THEIR PERSONAL USE RATES ON AN ONGOING BASIS. EVERY DAY IS DIFFERENT.
