On my Woods 59 I had the similar problem with the belt breaking, not with hitting clumps but trying to cut too tall of grass/weds. After the belting breaking twice I called woods they said two things: 1) the mower is designed only to cut grass maximum four inches tall … 2) try upgrading the belt to an industrial spec.
I did #2 early last summer and … so for no problems. The heaver belt is really stiff and hard to bend. I tried to find the manufacture name of the belt and I can’t find it, all I can see on the belt is a green strip which I guess means industrial spec. The cost if I remember was $15 more than the cheaper belt from the local farm store. On line probably a lot more savings.
