Adjustments
To get full performance from your NP4000 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 planting conditions rarely change, some of
these items need periodic adjustment due to normal
wear.
