SW Sask | Sorry, I should have explained. In most cases hairpinning was the issue with disk drills. In wet clay the slot would stay open in track tractor and drill castor tracks. On our farm, wheeled tractor (higher compaction IMO) would simply not work with disk for slot closure.
At harvest, yield was similiar but risk with disk is uneven maturity if you go without rain which can happen for weeks in SW Sask - maybe not a concern in your area?? Thin crop in wheel tracks or otherwise also causes significant weed issues.
I continue to feel that IF I could get a disk to work consistently it would grow more bushels BUT, in my experience, conditions have to be perfect and the operator has to be superior. If conditions change due to humidity from morning, noon, or night, the operator will have to continually monitor and adjust or simply shut down. Hired help will have to be top end only. For our farm, the more bushels would theortically come from moisture conservation in dry years.
Again, my experiences only. I have seen many farms use them and continue to do so. I just haven't seen the consistency that I feel is needed over the wide range of conditions and soils that I think is needed........
I would place the 3310/20 best in 90%+ and 3710 in balance for the drills we have run. The rest are a ways behind. | |
