Iowa | 1) pick up your rocks/ problem solved
2) discs make slabs/ribbons in many soils even when those soils are fit for a field cult
3) discs make ridges if not continually watched by a good operator
4) discs take MUCH more maintenance
5) disc blades break in rocks
6) discs PACK
In "flat and black" corn belt soils, discs belong out back in the fence row FOR SURE. If we were still discing in 2013, we wouldn't have hardly any fieldwork done. I doubt we've had a day this spring that the soils have been dry enough not to slab like crazy; a disc this spring would have ruined every seedbed it touched.
Machinery technology has moved beyond the disc. We left discs and 125 bu corn back in the '70's. | |
