It was a new unit fresh from the crate... the mesh of the starter and the flywheel was off and the person(s) who assembled it at the factory tightened it down, i guess thats where it got cracked.
as an update, I ended up getting a different machine, still a 910 though... I mowed 7 lawns with it last night and have an oppinion on the machine. It is much better than the 10yr old Exmark LazerZ hp that it is replacing.... I don't have a mulch kit on it yet, but in 2ft tall wet bahia, it mowed it down at 4in without bogging it down. I do believe a little more power would be nice,(power is always nice)
