Hi , I have been watching all the aog stuff for a good while from the side lines and I finally decided to set it up … I want to eventually set it up on everything but … One thing at a time I have figured I would start with my 4840 … It does tillage only so I figured this would be easier to test on to fine tune …my planting tractor has a raven smartrax system and it “works” so I’ll leave it alone …for now…before I start this build I wondering if anyone else has a set up on a 4000 series … And what was used for steering sensors …I would also like to set this up with a hydraulic valve apposed to a gear and motor … …any suggestions would be appreciated …
