Adjustments
To get full performance from the 2SF24 or 2SF30 drill,
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.
