Pretty impressive numbers Herb. You'd have to allow for refill time of the
huge grain seed tank, plus the two liquid fertilizer tanks being pulled
behind. No doubt they would still re-fill faster than I used to with a five
gallon pail.
Also it does occasionally rain here in seeding time so that would keep the
big drill out of the field, as well as the semi required to carry the grain
and granular fertilizer.
