Snake,
Read your Ground Cover article again last night, and was wondering how you have been getting on with your X20 as a controller for your air seeder? I am in the throws of updating carts, currently on a John Deere 787 (flexi-coil 1720) which doesn't support VR. I am leaning towards a simplicity with ground drive and linear actuators run by an X20.
Compatibility of file types between everything is all sorted, as I provide PA consultancy in the business I work for, aside from my farm and contract seeding business. I am leaning towards the X20 for: ease of use, backup service (mates with Topcon rep). I could run the simplicity via ISOBUS through the Pro 700 screen, however can't move it then to another tractor if needed, and the windows system in the X20 will allow me to run an RT200 Greenseeker (ready for next season hopefully) via farmworks mobile for mobile mapping activities.
Thanks mate,
Lach
