RM-425 deck will fit the short frame 854. I wonder why it says it won't fit the other short frames like the 877?

Was reading the RM-425 42" deck will fit the short frame 854, 1055,1075. I wonder why it says it won't fit the other short frames like the 877? I am not worried about the 8HP being to big because on taller grass I will just mow a little further to the right. the 42" deck would be a lot quieter too. I suspect it would fit and thinking they dropped it as an option because some complained the 8HP motor did not have enough ass.

BINGO,   Asking an 8 HP engine to swing 42" f blades is a bit much, especially if it is also turning a Sundstrand Hydro.
