Mower deck for 520-H 1991

[Wheelbearing 49]

Will a 42" rear discharge mower deck 78355 fit on a 520-h?

It should fit, but when I put my 42 SD on the mower wheels hit the rear wheels of the tractor. I think do to the larger rear wheels of the 520. I don't know it the rear discharge wheels are of the same distance that the side discharge is. It really became a problem when turning sharp. The deck wheels would just lock up against the tractor wheels and drag, thus tearing up the grass.
