TEST EQUIPMENT AND PROCEDURES CONTINUED
All testing should be done when the wind velocity is less than 5 MPH. If wind is present, testing must
be done with spreader traveling parallel (within ± 15 degrees) to the wind direction.
Do not allow loaded spreader to sit for more than four hours prior to testing.
Prior to driving the spreader through the test course, it should be driven at least 450 feet (13,716cm) at
spreader test speeds.
Spreader must be driven over the collection trays in ONLY ONE DIRECTION.
Position spreader at the beginning of the course so that vehicle will straddle center collection tray.
(Figure F) Set gate opening based on desired rate/acre according to theoretical application charts
supplied with each unit.
Drive spreader completely through course at normal operating speeds.

DATA RECORDING

Using the data sheets supplied with the kit, document all spreader adjustments required.
Using the funnel, transfer the contents of each collection tray into its corresponding test tube beginning
at one end of the trays and working towards the opposite end.
Record the volume in each test tube in the box on the data sheet under the corresponding tray position.
(Figure G) NOTE: It is highly recommended that ONLY ONE ADJUSTMENT be made between test
samples taken. If more than one adjustment is made, it will be difficult to determine which adjustment
was responsible for the change in pattern shape.
