Not going to lie, that 27 HP Kawasaki on a 54 would be an awesome combo.This same info is all over the net. It appears the only thing as far as engines goes is the availability of the FX850 on a 54" MOD deck now. The rest is for looks or function like cast iron spindles and quick release belt covers etc.

I own a 950 that had a MOD and I had a loaner 960 with a MOD for a few weeks several years ago. Even in heavy leaves, I never could tell much difference between them. No doubt the 960 is stronger, but I just never saw that much difference.How is z960 with 60 inch mod? Thats probably same as 27hp on a 54 inch cut? Probably a beast
