Brian,
Sorry for the delay in answering.
These blades seem to do a great job mulching - remember you have 12 cutting knives instead of 6 cutting edges. Mine is the 60" deck - (6' wide door on the shed).
I grew up in Randolph, NY (south of Buffalo between Jamestown & Salamanca) SNOW BELT from lake Erie
The blade will work fine as long as you have a place to push the snow, but the blower is GREAT !
Have you been to the Ventrac Web Site ?
