I am not here pending questions on which brand works better. Just want the make-up valves to work the back half accurately. Glad you guys like the ones you have. I think all brands have their individual weaknesses and strengths. After having Auto-steer I think anyone who tries it would like it. There is no question in my mind that the technology isn't catching on. Noticed the latest NH3 meter uses this same tech, now capable of sprayers never having to change nozzles, clutch packs, diesel injection, where does it end. Just wish CNH would recognize the need to fix this tractor.
