Adjustments
To get full performance from your 20- and 25-Foot Drill,
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.
