Trying to find the instruction on how to replace the 2 Motion belts on a Murry 30 in riding mower, model 309311x692a, belt parts 37x114 and 37x115. Along with replacing the blade on the mower.

Hi,
The manual is available here:

And the belts are covered on page 22. Blade is covered a few pages before.
Peace,
Clarke
