Motorizing the chute crank is definitely a different approach from what most people do. I have later model 521 it's someone had put out to the curb. Was told it had carburetor issues. When I got home I did start the engine and it started but of course it was still warm weather. I am planning on putting Predator engine on mine. It's interesting to see the subtle changes Toro made to his model over the years. Mine has levers on top of the handlebars and the chute is a little longer.
Guys who own this model or similar, could you please show how the gear box works on it? I have an opportunity to get one old 421 but it is in other town and owner said there’s only one gear works and he doesn’t know anything else coz he just gets it for free and resells. Interesting if it a big problem with those gears?
Yeah, OK. Despite this posters claims, removing the pulley from an engine shaft that’s 30+ years old, especially this one, is NOT easy! I’ve done this several times now and each one was a bitch!
And when I did the repower I broke I broke the pulley trying to get it off so I buying one on eBay. Made sure to put anti-seize on it if it ever needs to be removed.
What a nice idea with swipe motor 😅
I have a 1980 421 that I repowered with a 208cc briggs. You ain't kidding about the wheels. traction is BAD! sweet mods man!
It's good thing Toro came to their senses at some point and switched to pneumatic tires.

Nice find! I feel like these snowblowers were made to just run!

Sometimes you get lucky.

@@robertknight4672 good stuff!
I soaked mine in PB blaster overnight. Wacked it with hammer + big socket it. Then put a puller on it.
