Easiest to work on? Toro 521, 524 or Ariens 922020?

So I'm going to pull the trigger on a snow blower next week and would like to know which machine is easier to work on.

Which is easier to:
check and change the belts
oil the drivetrain
change the oil in the gearcase and engine
Anything I missed that should routinely be checked

Also, are there issues getting parts for any of these machines?

Lubricating the drive train should be about the same on all of them.

The belts might be a little easier to change on the Ariens since the front comes off with only 2 bolts and the bottom pivots on a hinge.

The Toro 521 uses the same frame as the 421 and 3521. I had a 3521 and a Harbor Freight Greyhound engine fit on it quite easily. The only issue was the chute crank needed a spacer mounted to the handles to move it out slightly. The skid shoe bolts use 2" spacing instead if 3" spacing so they are a little harder to find. The scraper bars might also be hard to find.

I have never had or used one of the Toro 524 series ones.

The Ariens is a compact model and probably uses a dual shaft engine. Those are hard to find replacements for. It is a little smaller than the standard Ariens, but a lot of the wear parts should be standard with the full size units and still easily available. The scraper bar and skid shoes should be pretty basic and still available all over the internet.

Please direct all snow blower questions to the forums and not to me with PMs.

Thanks for the information! Can you explain what a dual shaft engine is?

The camshaft sticks out the front of the engine as well as the crankshaft. The camshaft turns backwards and at half speed. Some smaller framed machines used that as a speed reducer to avoid having extra parts in the blower itself. The issue is almost all new engines are crankshaft only. This means that if you get a new engine your forward gears will all be reverse and your reverse gears will all be forward. All gears will also be twice as fast now.

i have an 824 which is basically the same as a 524. almost all parts for it are available, the engine is crankshaft only which makes replacements easy to find, all parts are easy to obtain access to and replace. i also have a 521 and it is basically the baby brother of the 824, 724, and 524 so like i said before, everything is easy to replace. also, gear sets for the toro augers are extremely easy to find(i paid 12 bucks for a used one on ebay) and they fit basically all of the toro two stages made before the powermax series
