If you want to run on 60" centers run 5 knives. The middle 3 would have 2 lines and the outside 2 would have 1. By running 5 knives you can avoid running knives in the wheel tracks, assuming your tractor is set on 60" centers.

I think simplest is to tee one outlet at the manifold & run  1 hose from each outlet of that tee to each outer end knife....which needs to be a double-tube knife. Don't tee into the hose already feeding that knife.

Sidedressing in Northeastern Illinois (60 mis S of Chicago) with NH3. This was a few years ago for us. Hopefully this YouTube isn't blocked out in Europe.

Photo below is sidedressing with liquid UAN (aka 32% N). Again, this is a 15 shank applicator that has 1.5x orifices on the end rows, therefore we skip one row when we make the return pass.

Below is a view from the cab of our NH3 applicator (JD 2510H). However, just behind it you see our UAN applicator. Both applicators are applying 1.5x on their outer shanks.

tigger,

Yes, I guess you could say that. I think we've completed 4 full seasons of sidedress w/our 2510H. No major problems. As you might notice, ours is utilizing the ANH3 system, which I very much like, and also the JD Pit Stop Pro....which has taken a lot of work out of sidedressing. We (me) don't even get out of the tractor to couple the wagon to the 2510. ANH3 system also assures proper dispensing since orifices are used vs just manifolding. I remember a few yrs back, there were always tests conducted gathering volume output information from NH3 bars & their appropriate manifolding systems. You'd have to catch the NH3 in a bucket of water to measure the difference between the rows in output. ANH3 works well.

I'm absolutely certain at this point our next applicator will be a JD 2510H....or whatever they may update to.

Seems to be a "here" & "there" thing. We've been sidedressing NH3 here for 40+ years. Started w/liquid before that. In this area, I'd guess that 95% of the applicators are set up on a "1 row short" setup. In other words, if you're applying 16 rows, you only have 15 shanks. If applying 12 rows, then only 11 shanks, etc. Then, we run 1.5 x on the outer nozzles, or if you're not using orifices, then split a whole barb out of a manifold & run 1 hose to each end from that split to feed a double tube knife. Never run 2 hoses into 1 tube....that won't work well.

I'm absolutely certain that our next applicator will also be of the "1 row short" configuration. Though I will admit, we have never come close to attaining the 400 bu, then 460 bu, & now 500+ bus necessary to win the NCGA. But, we're doing OK. Not saying this is the only way...just saying it works fine here.
