Looking to buy a "newer" drill for the summer, Seen a 4.5m krm optidrill but unsure wat they are like? Sowing bout 250+ acre a year,soil varies from sand to peat to heavy clay,quite steep aswell,got jd 6930 to pull it with. The way the weather is we want the job done quick so dont like power harrows. Looking to spend maybe up to 6k and would prefer a disc drill,any suggestions welcome?
