Just out of interest could you try the new m36 belt on the other mower that the old belt that looks like an m36 came off of.
wouldn't be the first time for dodgy manufacturing had stuffed up a belt
I hope it's a simple as that I know it probably won't be
Tyler, much thanks for the ideas.
Yes, I have already tried all the belts I have onhand M36, M36K, M37 and the Gates M38 on both mowers - which appear to have identical pulleys and layouts etc. There was no noticeable difference or info I could ascertain from doing this.
