Good morning Brad,
    Just a note to let you know that I got the Manual on Friday. Thank you!
 Have skimmed thru it but have not as yet had the time to look at it and absorb much.  I did see that it came stock with 18 or 20 inch discs.... mine measure 16 and are thin. I may put new ones on this spring.
 Thanks again,
     Cal Innes
