DETERMINING THE RATE OF CHEMICAL
The number of pounds of chemical required to be applied to a given ton of hay, depends on the
moisture and the type of chemical used. The moisture of the hay is important in determining how
much chemical to use. The wetter the hay the more product is needed, the dryer the hay the less
product is needed. By knowing the moisture, you can make sure you are treating the hay correctly.
Under applying will save money but spoilage most likely occurs. Over applying will waste money
however, the hay will be saved. Some chemicals require more or less to treat the same amount of
hay. To find the exact number of pounds required, for a given hay moisture, refer to the label on the
drum or contact the manufacture. Harvest Tec applicators come with low, medium, and high sets of
tips. If your chemical requires rates other than what these tips deliver you will need to purchase them
through your dealer.
SELECTING TIPS AND SETTING PRESSURE FOR ROUND BALERS
Once you have determined your tons per hour and the amount of chemical needed for the moisture
you are applying at, you can select your tips and determine your gauge settings.
1. Multiply the tons per hour by the amount of chemical required for the moisture you are
applying at. This sum will give you the application rate.
2. Select the proper set of tips from the application rate chart and install them. (Pg.29-30)
3. For the tips you have selected, you will need to keep the gauge at the recommended PSI to
achieve the proper application rate.
4. Set the pressure by adjusting the dial on the control box and by reading the pressure of the
gauge to match the desired rates. The numbers on the dial are for reference only. Rate is
determined by watching the pressure gauge.
Example:
You are baling at 22 tons per hour with your round baler. The moisture that you are baling
at requires you to apply 8 pounds per ton. Multiply the 22 tons x 8lbs. = 176lbs. per hour. Using the
chart, lbs/hr with three nozzles, on page 12, you will notice the green set of tips at 35 PSI will give you
that output.
CALIBRATION REMINDERS
*
Watch the pressure gauge, as the setting will vary with tractor’s electrical output, temperature
and other factors.
*Check your application rate by measuring product used against actual tons baled.
REMEMBER, ONLY YOU CAN CONTROL HOW MUCH PRODUCT IS APPLIED AND THAT WILL
DETERMINE IF YOUR HAY WILL KEEP!!!
