General comment: if you're using 2 spoked closing wheels, you really need a Keeton to do the seed-to-soil contact. Since they haven't been mentioned yet, I will throw our Thompson wheel into the ring. I agree with the statement that you should try some different wheel styles on your soil types. I think you will find that our Thompson wheel performs among the best in true no-till across all soil types for closing action, although it does essentially no seed firming. https://www.exapta.com/products/thompson-wheels-for-planters/ -- scroll down on this page for a diagram of how the various styles of closing wheels function. For durability, and staying free of mud and stalks, our T-whl is among the very best. best regards, |
