For Sale: New Idea 318 Grinder Unit attachment for New Idea 2RN or 2RW pull-type picker. It is in good condition, stored inside. As far as I know, everything should be there to mount it on your gathering unit and start making ground ear corn feed! Operator's manual is included. I'm asking $900 for this unit - call or text me at 507-920-9474 or email me at tomshaygrain@gmail.com with questions. Thanks for your interest!
