younggun23 - 3/7/2026 23:22 Looking for some advice on setting up an NH3 bar. I’m planning to put together a simple homemade bar and trying to figure out what all components I actually need. The plan is roughly a 20 ft ripper style bar with knives only every other row (16 row planter, but couldn’t pull a 40 ft with the sidedress tractor). The goal is mainly deep ripping some compacted ground and putting ammonia down while I’m there. If we get into a wet fall I don’t want to have knife tracks every row. I sold my old NH3 bar 10+ years ago and since then I’ve just used local retailers’ bars when using NH3. Most of my corn ground now gets solution anyway, so this wouldn’t be used on everything. One thing I noticed in the past was I seemed to get a good response from sidedressing where the deep shanks were ripping and opening the ground up to breathe, maybe as much as the nitrogen itself. I don’t necessarily need a rate controller or anything fancy. Just something simple that meters consistently. What all do I realistically need for components? I know I need the basics like a breakaway coupler and manifold. Do I need a cooler? I know they help regulate flow but wasn’t sure if they’re really necessary on a smaller setup like this. Also wondering if I’d be better off finding an old junk bar and rebuilding the plumbing/components versus buying everything new. Looking at prices of new parts it seems like it could add up pretty quick. Any advice on what all pieces I need or things I might be forgetting would be appreciated. I’m also planning to document some comparisons between NH3 sidedress, my normal 32% UAN sidedress bar, and simply running the ripper knives behind the 32% without adding additional N just to see what kind of response the ripping itself gives. Thanks
