I suppose these may be applicable to this topic. The snapper with the Honda GXV120 was built out of three mowers. The engine came off a deck that was in terrible shape, the current deck had a dead Tecumseh TVS90 and the commercial handles, brackets and braces came off of a mower I parted out. Runs great, as a Honda should. The other is a Subaru Robin EH18V that's currently not running (possibly bad piston rings) on an older commercial deck that I parted together from two other parts mowers. Currently working on an extra tough pusher - converting it over to self-propelled. Got a ways to go on that one.
