When I was a teenager in the mid 1970s, there was still a few farms left in north west New Jersey and we had a local IH dealer, Deere dealer, Massey ferguson dealer and Case dealer, all selling agricultural stuff. The Case dealer is the only one still in business and switched to construction eguip. I occassionally see a Case tractor in the back of a barn once in a while in my travels. The farmer that was my neighbor when I was a kid had IH and an Oliver with the straight eight cyl motor. He still farms, but mostly with old Deeres. The only Case I can think of near my work in north west NJ is a smallish farm tractor that one of the surviving dairy farmers still uses, probably early-mid 1960s vintage. I couldn't tell you a model number. Near my home in north east PA, it is either Farmall, IH or Deere. I went to an auction near Belvidere NJ very close to the PA border and there were about 8 Deeres and 3 or 4 Farmalls sold. I suspect that the majority of the area's old tractors have already been sold off years ago and what is left has a zillion hours on them and are held together with spit and wire.
