Been looking for a 72" mower for some jobs I have. well today I pick up a copy of AuctionTime.com. They got 8, 06 model 72" Scag STT35BV-SS's and all of them have between 4800 and 4300hrs. And all serial #'s are close. This guy really cut some grass!!!!. They are in Ca and they really look good for the hrs. Just wish they were alot closer.
