We recently purchased several pieces of Farmall Cub equipment from a local farm sale. The disc was labeled as a Homemade disc instead of IH like the other pieces. The sale also had a Pony that was in very, very poor condition. I have compared the tongue of the disc and the way it hooks up to my Pony harrowand the way it hooks up and I believe they are very similar. I was just wondering if any of you could tell me for sure that this is MH and what model it is if it is MH. The only numbers I can find are on the bearings and it is WD 28 and on the handle which is D2Y.
