The thread is left hand or reverse thread because the blade turns the opposite direction than the other blade. It is left hand thread to tighten the nut when the blade is spinning. Converting to a right hand thread has the potential to loosen the blade when running.
Got one who does a lot of commercials so he has some battery line trimers & hedgers because he can use them during normal trading hours without annoying his customers .
Before that he had to do all of the doctors offices on Sunday .
So now hic cews come in on Friday afternoon & do the hedges & triming and he comes in on Saturday afternoon to do the mowing

From my experience it's best to replace the spindle PERIOD #2 it's got to be rethreaded in the counterclockwise direction. There are plenty of shops that will do it for 25 bucks. Sounds like a lot but if that blade comes off and punches a 3-inch gash in the deck or worse - now it's more than a new spindle. REPLACE IT - maybe even ask the company for a mercy replacement for you the loyal customer. Many times a little asking goes a long way. Maybe ask them to mark it clearly on the next batch of mowers. Hope this helps
