Adjustments
To get full performance from your YP2425A Planter, you
need an understanding of all component operations.
Many provide adjustments for optimal field results. Some
adjustments were covered earlier in this manual.
Even if your planting conditions rarely change, some of
these items need periodic adjustment due to normal
wear.
