I realize this is an older thread.... but I had the exact same thing happen to me yesterday, belt came off and sliced through that plastic fan. Mower wouldn’t go anywhere. Purchased my mower in 2017 and this is the first time it happened.
Has anyone discovered more about this issue? Obviously it’s happening to multiple machines, mine is a 2017 Liberty Z 48”. Is this warrantied? If not, a fix that can be done DIY, or highly complicated? Thanks!
