Brother Tom is the expert on tractor Auto-Guides. We installed a bunch over the years. Newer the better but lots of learning and software upgrades. Gets most tricky with potato planters for the side drift is almost unpredictable. Trees are another thing ect. We still have not received first one for combine. We wanted it last year and more so this year. I hear it works well so I hope they have it right when we get it so there is no screwing around.
