You can find the belt diagram for the MTD Yard Machine mower in the MTD Owner Manual. The diagram is on page 21.

in most cases you have to take the deck competely off the tractor to replace either deck or drive belts on the yard machines. unfortunitly that is the way they were built. I am a lawn mower sales and service manager

Take your make and model number (located under seat) to your local lawn mower repair parts shop and they should be able to get you the appropriate belt.

If helpful, please rate.

I also need a deck belt diagram because a manual didn't come with my 746 SRL yard machine

Can you adjust tensioner

go to the online web site for the yardman this will give you the guide on how to replace the belt.

I have the exact same model MTD tractor with same problem. It began when the bolt that extends through the idler arm assembly broke and subsequently damaged the pulley. Upon examination of the broken bolt, I found that the threaded end that extends below the deck is significantly smaller that the rest of the bolt. I got a larger bolt with the same size threads, bored out the hole through the deck and it made the whole idler assembly much stronger. the deck still has some vibration and some unusual belt harmonics, but it appears to be working. Compared to most other tractors of this size, this deck is very complicated.
