Really need the real model number from the serial number tag but it looks like need the WorldLawn 4211002 belt. Can't find anything on the net here about it size but it appears to a 5/8 (B) belt.
I just wish OEMs would put out the belt sizes but they protecting their sales.
But usually it take someone willing to bite the bullet and order the OEM belt. then measure it and release the info on the net.
