Yes it will. That looks like the QA42A (it might be a QA 42--I'm not for sure, but either way it will fit your cub), so it is adaptable for either a NF (narrow frame, which is what your 147 is) or a WF (wide frame) tractor. If you have a pallet, then place the thrower up on the edge of the pallet and gently slide it in place. Be patient, this takes some finesse. It should do a great job clearing your drive during a heavy Pennsylvanian winter snow. Congratulations on a very nice purchase and
. You can go to our technical section if you would like to find a brochure on your snow thrower.
Oh, it is a single stage snow implement, so it is called a snow "thrower" and the dual stage snow implement is called a snow "blower".
