16 row coulter machine set up on a 12 row hiniker cultivator bar with extra welded on to make it 16 rows. Yetter coulter units with narrow knife for injecting the fertilizer. Units used 2 seasons maybe 1500ac on them total. Has rear hitch to pull fertilizer cart and red balls that probably need replaced. Would sell all together or just the units if that's what you're into. Open to trades also let me know what you've got.
