Massey Ferguson 6290 socket/ spanner size question?

[Pilatus]

I need to undo the transmission filter out casing( the large filter on the left hand side of the transmission housing, if sat in the tractor), do any of you the size of the socket spanner I will need.
As per usual looks to be a delightful job Thanks for any help.

It’s a 50mm spanner on a 6480 so presume it will be the same on a 6290
