Constance, it sounds like you may have sheared the flywheel key. if the engine turns over but wont start i would take the covers off the engine and check to be sure the key is still in position. if not replace it. there are videos on you tube that show this process. be sure the blades are able to move to the free position also. if something is jammed the belt or blades it may not allow the engine to start.

I have a Yard Machines Mtd 22 pushmower and the model number has been worn off. I need a manual for it but the web site requires a model number.

A lot of machines are generically produced. MTD is made in the same factory as: Craftsman, Cub Cadet, Some John Deere, Green Machine, Yard Machine, etc.
So if you find a comparable model to yours, that manual may suffice for the part you may be in search of???
Go to your local DIY center, take a picture with your phone, of the name, & S/N tag of a mower similar to yours.
You may get lucky with a Craigslist Seller of a 22" MTD to give you the appropriate numbers? Just trying to assist you.

My MTD Yard machines riding mower won't start.

Probably dead gas from sitting too long. Dump it out & put in fresh gas.Could have moisture in it. Pull out spark plug & crank it over several times after putting gas & let it sit a while to dry out or blow it out with compressed air. It should go.

What does it matter how much they cost. Go to the home depot of the like and buy new blades if you need them. Most of the time all you need to do is sharpen them did you go that route yet??? Lefty loosy righty tighty...

If the speed seems to be different after changing the belts, it should return to normal after they break in.

The 600 series has a top speed of about 5 - 6 MPH, see:*&p_li=&p_topview=1
