yes it does have the left side exit on the deck,I wondered about the left hand threads,but wasn't sure. thats another thing that I'm thinking,I have just used the mower 1 time cause we didn't get the tractor and mower till the end of the season last year,but exiting on the laft side changes the way I have mowed for the last 18 yrs,now I need to go the other way to discharge away from house and everything else.thanks for the replies I'll try going the other way righty loosy,lefty tighty.
