I have all the other parts for the snowblower and tractor. I haven't been able to find the engine pulley. How safe would it be to make one? Are there alternative engine pulleys?

If I would of known they were that hard to find I would of kept a couple.

Maybe you could cut up an old Briggs pulley like one of these.I keep all the Keyed engine pulleys that I can find they come in really handy when you need to make an engine pulley.

Cut the big end off of a pulley then Tap the crank for a long bolt and weld a heavy washer to the end of the pulley sleeve.

Nice Custom!

I wish I could help with a source for the pulley. Having one, I could provide dimensions if needed.

Thanks for the close-ups of the belt cover; this is the only piece lacking from my setup. They may prove useful as I am contemplating making one. Could I trouble you for the sizes of the "box" area holding belt retainer?

Yea, I did the same many years ago. Had a handful of them and threw them out. I could do this. I have no problem with cutting up a briggs pulley. They're easier to find but I'm not sure about tapping the crank. Ill have to draw up a picture of what i'd like to make.

EDIT: I was able to find calipers and get a measurement of the crank shaft.

1" OD
1/4 ID

What I don't understand is how the pulley attachment holds onto the crank. The crank has no threads for a bolt. Do I remove the current pulley and then slide on the pulley for the snowblower?

My bore is 1 1/8 inches (10 hp) Set screw location is: one on the key, other 90* away. It may be possible to take the original pulley and weld the extension pulley to it.
Awesome. Thank you. Now knowing what it looks like, Ill just get a replica pulley for the main drive and the snowblower and weld both of them onto a pipe. then drill and tap a couple threads for set screws.

I've read (have no actual experience yet) that the blower could stand to run a little faster. Maybe consider going to a 4 1/4 inch drive pulley for the blower? This would of course require the fabrication of a new slightly bigger belt retainer.

If I were to make this; try to start with a sleeve with the set screws and keyway machine into it. Add pulleys in the appropriate places.

Double pulley at the engine end is only to run both the drive belt and the deck belt, only necessary if not removing the pulley for summer duties.

Good luck
