Bought a Case ATX700 60 foot with Pillar lasers on it (conversion done before Pillar was building the wider drills. Has 3430 CNH variable tank on it as well. Have about 900 ac done with it this year and I like it. Folding takes me only about 3 minutes. Cart calibration very nice. Hate that can't put any tank into any run. Seems dumb that it still has to be that way! Air system leaves much to be desired with seized air deflectors before the tanks.
