check amd make sure the drive disk is not rubbing on the clutch and brake assembly.
Mine also makes a noise - and has since new. My last RER also had the same sound. Check all the obvious things, and don't worry about it if nothing is found.I have a question about how it should sound when I push it around without the engine running. It sounds like metal rubbing in the rear of the mower. I was just wondering if this is normal? Could it be a clutch sound? I have used the mower and it seems to work fine, it just sounds like something is rubbing when it is in neutral and i push it around the garage. Do they all make noise when being pushed around even out of gear? Every other mower I have ever owned didn't make any noise in neutral.
Thanks,
Swami
