Adjustments
To get full performance from your NP30A or NP40A
fertilizer applicator, you need an understanding of all
component operations, and many provide adjustments
for optimal field results. Some of these have been
covered earlier in this manual. Even if your application conditions rarely change, some
of these items need periodic adjustment due to normal
wear.
