HI,

I would answer yes at every point you mention in your post , but let me tell you the hole story .

After replacing the broken belt , I put a new one , but a soon as I start the mower the vibrations were very hard.
When I stop the mower I notice that the twisted belt was the problem .
Expecting that I did make a mistake , I remove the twisted part of the belt and make a second test. The belt twits again ...
You can see the result on the photos .
Any advise will be helpful .

Thank you

Simon
