Question for the MTD guys.

 

Can you mount a 50" mower deck in place of a 42" mower deck on a 990?

Whats involved to do this?

Pictures?

 

I guess that's 3 questions.

Not sure if I can answer doug I just received 2 mtd 990's myself and pondered that. I would assume they share the same deck linkage just a bigger deck is all.

As far as I know, they're interchangeable within their mounting style (early scissors linkage vs. late quick attach)

 

I've also wondered if the later quick attach decks from the 995/998/999 series fit the quick attach 990s.

i would say that they do interchange.

the only difference ive seen in what i own is the shafts. the newer 995 & up have a splined shaft and older 990's have square.
