id like to get one to fit behind the 15' krause no-till drill to make one pass... looking for some suggestions. 15' or 17'? or should i just scrap the whole one pass idear and get a big un? there may be an increasing demand to run one of these cusom-like, with dairy farms and new seeding, may be another reason to go wider.

ive got quite a high clay content in my soils, however i dont or cant drill when too awful sticky...should i be concerned with finding a roller with a scraper?
