I eneded up removing the brakes and cleaning the contact area of the pivot and applying anti-seize. I aligned the brake pads so they contacted the pullies squarely.
Works fine now. Thanks to everyone for your responses.
I think I have it fixed. I took apart brakes and cleaned and applied anti-seize to area between deck and brake bracket. Also adjusted brakes so they hit squarely on pulleys. Thanks for all the help.
Thank you
Thanks for your reply. This is the third belt. All are genuine John Deere belts. When I start it up belt is fine. No noise. Sometimes it starts to make the noise and tries to turn.
I have a John Deere D125. 9 years old. About 250 hours on it. It broke the deck belt.
I replaced the PTO cable as old one was stretched.
I replaced the housings over the deck pullies because belt wore threw right side cover.
I replaced left spindle bearings because they were little noisy...
