What belts do you use on your mower?

Mower belts live a tough life. Not many applications punish like a mower deck. Shock loading, heavy loads, dusty conditions, moisture, you name it, a mower sees it. Standard industrial belts will not hold up well at all vs OEM or a belt specifically engineered for severe-duty or mower applications.

The 2A belt (vs 2B) is likely the culprit for short life vs your other equipment. Especially given the relatively low hours.

Much can be gleaned on why a belt fails from examining the failed belts. Even if tension seems good, I'd put a real tension gauge on it and consider adjusting if slippage is an issue. Next, I'd check the profile of the sheaves/pulleys. If they are worn even slightly, there will be an adverse effect on belt life. A cheap mechanic's stethoscope should tell you all you need to know about idler and spindle bearings. Straight-edges for alignment.
