Adjustments
To get full performance from your 3PYP, you need an
understanding of all component operations, and many
provide adjustments for optimal field results. Some of
these have already been covered earlier in this manual. Even if your planting conditions rarely change, some of
these items need periodic adjustment due to normal
wear.
