There are several mowers that could be used. Trailing mowers such as the New Idea of years ago could be used behind any tractor. I would prefer a mounted or semi-mounted. I have cut many acres many years ago (1950's) with an H and an IH semi-mounted. Can't give you the model number however. The swinging drawbar was swung to one side and the mower was bolted rigid to the drawbar. There wasn't any left-right movement between the tractor and mower but the mower could could move up and down A square corner was easy once you got the hang of it. This would be my choice if one could be found. I have also seen a picture, once, with an H and mower mounted between the front and the right rear wheels. Manfacturer unkown. Odd ball but interesting. If you come across an old Brillion mower - conditioner the mower is is an IH. Probabaly a lot of work remove even if possible. Jim Becker would know I'm quite sure about IH mowers that fit an H. Vern
