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. Other side is fine.
I replaced idlers as they were noisy.
I replaced brake pads and springs.
I replaced belt.
All guides are in place.
When blades aren't engaged it sometimes make a squawking noise.
When this happens deck belt is trying to turn.
New brakes don't seem to hold pullies. The brakes pivot freely.
Any thoughts? Any help would be appreciated.

I would be checking your belt size. It wouldn’t be the first time we’ve seen a new belt that is too short, wouldn’t take much, that wouldn’t allow the spindles to completely release.

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.

Some part of your deck isn’t right. Double check the size of belt to be so it is correct. How is the belt tension on deck belt when it is engaged? Double check all the spindles and pulleys for free movement and being on a level plane with each other.

I agree with Tiger Small Engine. Some other ideas: Is there an adjustment available on the brake? If so, maybe tighten it up a little. Is the new PTO cable properly installed or is it defective/wrong size? I’d be tempted to put the old cable back on and see if the noise goes away. Are the pulleys worn and polished from having the brake pads rubbing on them, making the brakes less effective?

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.

Be sure that the belt is the correct WIDTH as well as length. I just restored a LA125. Belts also wore through the guards. I pop riveted a piece of SS on the outside. Some shields had a metal pin in them to stop this. The squawk might be from the Clutch. Try the old PTO cable if you still have it. Some brackets on the deck of those are adjustable for the cable. Be sure it is installed correctly.

Make sure the tensioner pivot is not rusted and pulling all the way off. If not the brake pads will never touch spindle pullies. If brakes are not hitting pullies that is is something to check. Also make sure pto cable is in the grove by flat idler pulley.
