Why do you say you need HP or RTK for autoswath? I have a-s on a Hagie sprayer using only WAAS. Also have same on NH3 sidedress bar & UAN sidedress bar. All use only WAAS.

I'm wondering why repeatable sub-inch accuracy would be necessary on combine? We gave up on trying to combine corn w/autopilot & RTK. Just using HeadSight guidance now.

I'm not arguing...maybe I missed your point.

Thanks
