Not to my knowledge, but I wish they would, especially a hydraulic shuttle. To get that you'll need to go to the Farmall C series. If you look at a Farmall 75C you will get the same engine as a 75A but with much better operator platform, transmission choices, hydraulics, rear end, etc. Of course more money.
Yeah I've looked at the 75C but it's about an $8000 increase from the 75A. Little more than I'd like to spend for what I'm using it for. But I do like the C class. I would like to have a 95C with a cab when I'm ready to add a second tractor.
