Iowa | Was there a difference in overall average yield across the planter width between these planters? I've always wondered if you're really solving the problem trying to eliminate pinch row compaction. In my mind, things like hydraulic weight transfer just make the compaction more consistent across the wheels of the planter. They don't magically take weight off the ground. You're just shifting weight from one place to another. That might narrow up the range of variation, but if you go from 4 rows with a 12 bushel lag to 8 rows with a 6 bushel lag on the same width planter, you are still losing the same amount of overall yield to compaction.
On the DB88 a 12 bushel per acre loss on 2 rows only equates to less than half a bushel per acre total yield loss. Cutting that in half with the TrackTill gains a quarter bushel per acre. At $3.60 corn it would take 22,222 acres to pay for a $20,000 TrackTill system. | |
