wbb, your picture sure looks like the Oliver I used baling hay. I think it was a 1755 (not sure now), but I am sure it was a 6 cylinder diesel, supposedly about 80hp and 1972 vintage, with 6 forward and 2 reverse gears plus the 3 speed "Hydraulshift" I was thinking it said on the side of the hood. The hour meter showed about 5,000 hours when the neighbor bought it, but it was a very nice and reliable machine.
