Adjustments

To get full performance from your YP3025A Planter, 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.
