Measuring Travel Speed
Measure a test course in the area to be sprayed or in an area with similar surface conditions. Mini-
mum lengths of 100 and 200 feet are recommended for measuring speeds up to 5 and 10 miles per
hour, respectively. Determine the time required to travel the test course.
To help ensure accuracy, conduct the speed check with a loaded sprayer and select the engine
throttle setting and gear that will be used when spraying. Repeat the above process and average
the times that were measured. Use the following equation or the table to determine ground speed.
