A snatching clutch is the most likely reason, or a dirty carburetor. Lots of help in the link https://www.google.com/search?q=engine+runs+fine+until+I+engage+the+mowing+deck ..

If you killed the motor by jamming the blades, the mower belt may have come off or broke. Check to see if it is still in place. Also with the engine off, turn the blades by hand and see if the upper pullies turn.

Check the start relay (not starter solenoid) energizes during crank. If the start relay does not energize then the magneto kill shunt is closed, hence no spark.

Comment for further assistance.

It seems to be a common issue when you change a belt! Most people have it the other was when they won't turn. https://www.google.com/search?q=Ariens+snowblower+932102+auger+will+not+stop+spinning ..

Did you remove the rear screw located beside the dipstick tube?

Starter energize requires the following.

PTO - Off
Steering arms - Out
Ignition switch - Start position
Battery + fuse intact
Battery - fuse intact

Cycle PTO on/off, steering arms in/out. Check both fuses. Check battery voltage >12.0V.

.8mm will get you sorted.

perhaps the seat safety switch has dirt on the contacts

Get a haynes or clymer book for complete service n repair

The problem likely is with the SEAT/PTO RELAY not remaining energize. Look for open or disconnected wire (PURPLE) from the relay towards the ignition switch.

Ignition timing slightly out would be the main reason. Dirty spark plug is another Dirty carb is the last I thought of another. Failing battery. It doesn't have enough amps for cranking and spark.

Likely you will need to remove the deck from the mower.

Then remove the blade, tray, and retainer to expose the woodruff key. Remove key and spindle should slide out of the spindle housing.

The "START" relay needs to remain energized. Could be seat switch or other. See link below for wiring diagram.
