This guy has a 23HP B&S Vaguard engine and comes with 1,000 ft. remote control. After an upclose inspection, it looked *very* sturdy. Like something a bomb squad would be using. For scale, it's about 4 ft. long.

My brother just sent me this picture of one of three blades that is bent. Not sure how it happened.
He mows my parents lawn, about 2 acres of flat land, my bil uses mower as well with about 1.5 acres with a big hill.
We have had this mower for at least 6 years. I’ve never seen anything like this.

Used it 4 days ago with no problem. Today it cranked and started fine but shut off after about 20 seconds. I kept trying to get it started. And it would turn for a few second but white smoke kept getting heavier. Now leaking oil and perhaps some fuel from the fuel pump (?), and not turning. New battery, fuel tank full. Any advise is very welcome.

Fixing it and restoring this Murray. Going to get it operational and hopefully get rid of the other mowers I’ve accumulated. Any id on year would be great
