Have you found a solution for this problem? I recently aquired one the these machines and am having the same problem???
What year machine do you have? I'm not certain if later mowers have/had any belt issues. Mine is a 2015 year model.
I haven't had any belt breakage issues per se, but have replaced one of the long belts from engine to mower deck blades in around 125-150 hour timeframe.
I got a correct replacement from Mfg supply. It is important to get a belt by actual length, even more so than by part # IMO. I had my dealer order a couple of belts for it and they were both WRONG. It must be the belt for the 103 combi deck- if that's what you have for a deck. Mfg. supply was able to cross reference the belt AND specify length. I measured my old belt and the spec was the same as the new one, so I knew I had finally hit gold!
Sad to say, as I reported a few times on mytractorforum.com, I'm close to having my second rear transaxle replaced by my dealer. First was done under warranty when I found the trans fluid reservoir was leaking down between uses. It had a huge palm of one's hand glob of white silicone slapped up against the transaxle shaft to attempt to stop a leak that had to have been obvious at the factory. I didn't find the source for a week or so due to my having a Swisstrax grid pattern floor over my concrete garage bay floors for water and snow drainage. When I put down cardboard under the mower the leak became obvious.
So, at around 35+/- hours the dealer replaced the bogus first rear transaxle, then I noticed, after moving the mower to my new storage shed/garage bay that AGAIN I had a rear transaxle leak going on!
Now, somewhere between 125-150 hours, (from memory), I called my dealer who talked to Husky, and the best offer I got was Husky would supply a third transaxle, but I had run over the warranty period, so the labor would be on me. Oh, and they'd give me a $25 coupon toward what will amount to be at least several hundred dollars of labor cost.
I argued that had either Husky or Tuff-Torq, the transaxle mfg. done their job of quality control the first transaxle would never have gone to the retail customer, - me. And had that been the case, then the current, second leaking transaxle would now have been replaced during the warranty timeframe, and I would likely be a happy Husky customer. But no, neither one wants to take responsibility for a blatant lack of quality control. In fact, someone must have signed off on sending out the original silicone globbed first transaxle - which should have never left the factory floor.
Finally, I'm going to have to pay several hundred for labor I have no reason to spend because of Husky's inability to build and stand behind their product sold to me at retail.
One other point, in recent posts here I see a 'blade brake' being referred to quite often. I believe the correct name is the 'belt brake', which is a thin metal piece with a pad attached to one end, that is designed, IIRC to keep the belt from falling off a pulley; not as otherwise implied, to keep the blades braked when they are disengaged.
On a side note I went looking for a more reliable mower than the 322T and found one for not a lot more money. Don't get me wrong, I like the 322T a lot, but just can't deal with all the problems I've had with mine in very few hours.
What I found was a Cub Cadet Pro-Z 160 with ALL Wheel Steering. It is an AWESOME mower. It is a ZT, BUT with all wheels steering it performs better than any other mower I've ever owned. It has the Kawasaki 23.5 HP FX-790 (?) carbed engine. The deck is solid, prograde materials as is the rest of the machine, AND it has a long range with two gas tanks, around 8 gallons total fuel.
Unlike the Husky, it has greater than 3" max deck height, and the model 160 has a 60" 3 blade deck. Here's a link to the details:

FWIW, I plan to keep my 322T Husky. BUT if the 3rd transaxle even weeps, the machine is gone!
Pm me if anyone has any questions about either machine I didn't cover already.
