Choice of discs
I am looking at discs. It will be used on soybean stubble as a primary tillage tool either fall or spring or both to be followed with a field cultivator. I am doing this as a way to eliminate 1 spraying and to control marestail. I have looked at several IH 496's. Since the Deere dealer is closest I would rather stick with green. I found a model 630 Deere disc several thousand dollars cheaper than a comparable IH. I know the 637's are a good disc but have no knowledge of the 630 models. Does anybody know how the 630 compares to either the IH 496 or 490 models?
