The deck plate belt came off my 1984 Murray, 18 h.p. 694c.c. 3 blade mower.I don't have a manual. Does anyone have a belt diagram? When the belt came off it got chewed up so I can't even tell how big the belt is to replace it. Any help would be great.

Hi,
My guess is you have on of the oldie goldie 42" decks from that era. I will do a bit better than asked. I will post the picture and a link to a parts breakdown. On the parts page scroll down to the machine desiganated as 84-39003_84-39004.pdf and it will yield a printer-friendly Adobe Acrobat Reader document.
