[QUOTE="clbarclay, post: 7199842, member: 6671"] I would save the cash from bout markers and put it towards an auto steer system instead. My experience of bout markers while direct drilling is not great at best. During a GD demo, I gave up using the bout markers as most of the time I was relying on lining up a bolt on the front mudguard with the outer row of the last bout to get me in the right place to find the illusive bout marker mark. I even had Guest on my tine drill at one point. Mounting them on a pig tail cultivator wasn't even as straight forward as we had hoped either. I am quite pleased with how mine is working out, but it is still a work in progress. I finished rigging up zig zag harrows on the back of it and gave it a quick test today, ready for drilling beans. Not grate for trash flow, but finally got a harrow on it that really covers the slots well. [ATTACH]916038[/ATTACH] Personally, I think that even the commercial drills have their sort comings, so buying off the shelf won't necessarily work as well as you want.
