Sounds like you may have too much slack in the drive Chain. Pull the bottom cover off and look. Usually there is a way to move the shafts to tighten the chain.

Instructions come with your manual. Contact Toro for details.

Any chance it won't come up when you have the "drive" handle down ?? Newer snow blowers are often equipped with a "one hand" feature that will keep booth the auger and drive handles engaged (down) with only one being held.

If the chain is falling off the same side of the sprocket it as an alignment issue. May be a bad bearing somewhere causing this issue.

Look on the unit and find the model number. It usually starts wit 917.
Find it and then go to sears.com and type in the model number.

First remove the chain--- lay it flat on the floor --streched lengthwaze . grab either end and pull out and push back--- if chains length moves more than a quarter of a inch ---replace the chain. Next inspect the sprokets, if they are worn inward on the side they will let the chain drop on too far making the chain jump and rattel as it runs and this will throw the chain. Next inspect allignment of each spoket to the next sprokets with belt drive the belt will flex and this is not critical with chain drive this will load one side of each spoket causing the chain to jump off.

one of 2 things.if your spockets are worn the travel distance has shortened and where the master link connects replace the link that connects it with a half link.also is there chain tighteners on it?if so and they are on both sides of a spocket or just 1?if there are 2 they must be tightened together in unison and not 1 side or the other as that will throw the correct alignment on the chain and it will jump the spocket.also check the spocket alignment to make sure that is correct.

top idler sprocket was out of alignment,staitened plate it was attached to, then chain was running true and went on just fine. it was an old wheel horse snowblower.

Two things you can do. First if you look close you may see a spot where you can adjust the chain tension. Nest your chain should have what is called master link. Look close and you will see a clip that undoes the link. Pull the link out and the chain will come apart. If you are not mechanically inclined take it to any small engine shop and they will take a link out for you and then you will be home free.Hope this helps. donnyb60
