The snow blower is actualy for a gt-18 hydro. The snow blower has to be for a suburban model with the front slide in mount.Hi LJ.
I have a Haban 1-stage blower that will NOT fit the Suburban, unless you do extensive remodeling of the mounting frame and auger package. So, I believe, you will need a Suburban specific blower.
Now, maybe a blower from the early years will fit the Suburbans from later years, and vice versa, but I'll leave that up to the experts.
Have you checked that number thru the Craftsman fit-up guides that are in the stickie section? Also, how about the instruction booklet on www.sears.com or www.managemyhome.com . It might say in there.
