Looking at a new drill. Which one? Like option to stay 10 inch spacing with Bourgault by using mrb's to improve trash flow but not sure about maintenance on mrb's. Allows me to use narrow openers. Contour is much simpler but don't like wide openers on 12" spacing in dry conditions. I would stay 12" with contour to improve trash flow. I like the Bourgault tank a lot better than the Morris. I am considering Bourgault tank on Contour drill but I need sectional control and I am not sure it will work with Bourgault tank on Morris drill. Thoughts? Most worried about mrb maintenance with Bourgault and wide openers on Contour in dry conditions.
