CALIBRATION FOR FORAGE HARVESTERS, BAGGERS, AND SILO BLOWERS
There are two steps that you need to know when calibrating your applicator: determining your
ton/hour and using the correct tip(s) and PSI.
Step 1
Time how long it takes to process a load. Determine how many tons are in a load by weighing it and
use the chart below to determine the tons you are processing per hour.

Chart based on continuous feeding of machine
Example:
It takes you 10 minutes to fill a wagon. You weigh the wagon and determine you are
making a 10 ton load. Looking at the rate chart above, you see that you are chopping at 60 ton/hour.
Step 2
Look in the chart below for your determined ton/hour. The left column will tell you how many and of
what size tip to use, and the top row will tell you what PSI to run depending on the tip.

Additional rate charts found on page 15
Example:
You are chopping at 60 ton/hour. According to the 16oz per ton rate, you would use two
XR11001VS tips at 15 PSI.
