Good old honda hru173, I had one for a while, there is an article on the net somewhere claiming the deck is bulletproof and somone actually tried shooting one. Powered by a GV100 engine its the vertical shaft version of the G100 that I love to fit to scott bonnar reel mowers.
Bulletproof HA HA. Couldn't prove it by the HRX217 sitting in my junk pile.
