Hi I don't know the model number of this mower but it a snapper and its kind of little and cute looking very used and says briggs and straton on it 10 hp and 30" single blade. I bought it used and the pully is no longer used to start it, it now starts with the key turn and choke. I need to replace the belt, i measured it and it was 73", I don't even know what kind to buy, if anyone could help me.

Thanks

If you had a model #, I'd say go to DAYCO.COM - MARKIV Automotive Aftermarket. The lookup by dimensional data doesn't seem to work for lawn stuff. The lawn stuff begins with the letter L. You can look up by Snapper model #.

I can't even find the dimensional data for the L series belts.
You would need the outside circumference and the width of the belt at a minimum.

Once you get a Dayco number you can go to a NAPA store and get a belt. It won't be Dayco, but it will work. It is important to get the right belt.

You might have luck calling Snapper, especially if you can locate the briggs engine info like model and type which is on the blower housing. It's stamped and usually difficult to read. They may be able to tell you where to look for the model

You might have some luck calling Dayco too. Who knows.
