Wheel center settings

[Hair Bear]

Does anyone know what the narrowest front and rear wheel settings are for a 550? I'm guessing with 11-28 or 11-32 rears it's 52" and 48" for the front?

It will be nearer 56" and 52" on a 550.

Hmm... I did wonder, thanks. Haven't been able to find a setting chart anywhere.
I've looked at several and all had the wheels set in different places or various sized tyres and despite measuring I just couldn't visualise what I was hoping to see. I was intending to pair it with a B12 plough which I know works with a 52" rear track. Maybe a bit of cross shaft shuffling perhaps.
Any idea what the correct era plough would be? I'm thinking a MF 40 or MF 150 but info appears scarce.

Would think it would be a MF 40 plough. Which was available new in the seventy`s.

Thanks. Let the search commence.

Well... having now acquired a handbook (tractor not arrived yet) it does suggest 52" is possible at the back but I think it's going to be feeler gauge tight. Once I actually get to try it I'll report back.

Just to wrap this up, the answer according to the manual is 52" to 72" at the front, 52" to 76" at the back.

For future reference, we managed to get 52" on the rear, not as tight as I thought it would be, put a 10" Fergie plough on and took it completely untried straight to a match. All seemed to work ok.
