A friend (not in the landscaping biz ) has a 15 yr. old Craftsman 14.5 Hp riding lawn mower and was cutting grass in the rain a few weeks ago. He said the wet grass started jamming up the mower blades but kept cutting anyway. Afterwards it seemed as if the belt stretched as anytime you'd hit thicker grass it would start to bog down. He just called & told me that it's gotten real bad, when you hit thick grass (that it should be able to cut easily) it bogs down and starts to squeal and both the blades & engine RPMs slow down considerably. I told him I wasn't sure what it was but that it sounds like the clutch, any ideas, other than not cutting w/ a POS in the rain?!
