I"ve a 10 acre field that I"ve hayed for the past 20 years. In all that time I"ve done virtually nothing to it but spread some manure. The problem is the field is really wet and seems to be getting wetter pushing out when I can actually cut it and bale it. There is a drainage ditch running through part. My thought is to get a subsoiler and make runs from the ditch out through the field. I"m thinking this will help with draining the wet areas quicker as well as the likely compaction that"s taken place over the years. I"d like to find a single shank subsoiler that has a coulter so I don"t tear up the field as much but it seems all the single shank subsoilers don"t have them. Has anyone rigged something up to attach a coulter to one of these units? Any other ideas would be welcome. Thanks.
