Prepare the test
ü
We recommend a testing area that is horizontal in both directions. The tracks must not have any
significant cavities or heights since this may distort the spreading pattern.
u
Conduct the test on a
dry
day with
no wind
so the weather does not affect the result.
u
Carry out the test either on a freshly cut field or on a field with low vegetation (max. 10 cm).

Layout
We recommend the layout plan up to a spreading width of
24

. A layout plan for greater working
widths is included in the PPS 5 practice test kit.
