I have to replace the steering shaft on my 1999 series 660-679 42" mower. Does it come out the top? Also, how to separate it from the dash board.I checked underneath and a philips head screw holds the cap on the bottom of the shaft. i know it will have to be taken off regardless. Thanks a lot! fkg412000@yahoo.com A diagram does not tell me enough. How does it come out?
