I mentioned the other day in somebody else's post that I thought the wide front with the brace on top was wider than the one with it underneath. I had it backwards. Here's what it says in an article about the 1950T in the May/June HPOC magazine. I'm quoting, so don't shoot the messenger.
''The 1950T Row Crop could be ordered with five different front axles to meet the needs of the farmer......What doesn't seem to be widely known is that Oliver also had the narrow tread adjustable wide front axle that allowed for wheel spacing needed in narrow row crops. This axle can be visually identified, as the wishbone support is attached to the top of the axle tube on the narrow tread, and on the bottom of the regular tread.''
I would have thought it would have been the other way around since the one on the bottom came later as did narrow row crops, but I measured the ones that I have and the center tube is a little shorter on the one that has the brace on top.
