A long time ago, kovar made small(ish) pull type coil tine harrows called pony cart. I think they were meant to hook behind a disk. the one I had seen was around 20’ and had 2 wheels. Anyone have one of these setting around? Hope to use it for seeding grass .
A 10-15 foot fuerst or chain link harrow might also work for this. . 515-5thre8-029five. Text or call
