Southeast MN | Here, SE MN, we didn't really need them in sod. I would base the decision more on the condition of the bottoms than if it has coulters.
Up until the late 80's we ran IH low clearance, semi mount moldboard plows. I think they were 510 series. One had "cover boards" and one didn't. Anyway, we ran without coulters in sod or corn. In sod it was a piece of cake, the deadfurrow might not have a nice clean edge but if you can pull the plow fast enough (5 mph) in dry ground it would roll and shatter the soil. The mulcher would level any high spots and it would be ready to plant. Then I found a white 548 at a sale for scrap price and with more underframe clearance and good coulters it would run right behind the combine in corn stubble. It was a real treat to run that compared to the IH. Finally sold the white a few years back after a long retirement in the shed. | |
