    Interesting as I have both a 3414S and a 3416H from that 73-74 era.  Have a Front Cut 48" mower for grass but use the other 2 for snow blowing, thatching, spraying etc.  Both oldies used year round.  No major problems with either of the oldies.  Both purchased new.  Best investment I ever made.
