I put together a unit this summer using without using a ton of money. We never got to use it this fall so there are some things I will add before we use it this summer/fall

Aircart

Flexi-Coil 2320 with course meters converted to hyd. drive for single product VRA.  All cart functions are control and monitored with a Trimble FMX and the True Application System.

TO DO: dual product VRA.

 Toolbar

Built by us back in the 80's and served as our NH3 toolbar for many years.  It was originally 19 knife so I had to cut the frame down to 16 knife. We plant with a 24 row planter but did not really want to give up any width on the toolbar. I have thought of a way to counter that though without implement steering. As for the row units they are nothing special.  Just Shield-Ag dry fertilizer knifes and DMI closers. All 16 rows are monitored for blockage which is also with the FMX display.

TO DO: row cleaners, just because. And mabey to some more frame mods and make it a 12 row?

Nothing special but I think it will get the job done, whenever we get to use it. Not sure but that might be too much tractor on there.
