Single disc NH3 / liquid fertilizer applicator. 20" spacing.  Applies fertilizer in bands about 5 inches below ground.  30' sdx frame converted over. Row units have firming wheel removed and a 26" disc is used to cut a deeper trench. Nh3 and liquid are applied at a high pressure to inject them into the bottom of the trench and then closed with a notched closing wheel. Works great in low residue situations. Reason for selling is I bought a larger unit that matches my planter width. 30,000 obo. Call for more info. Six206one76nine0zero
