Adjustments
To get full performance from your YP425A, YP625A and
YP825A 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.
