Good luck. Try to post more information on the mower, brand,type,year,last four digit of the serial number and even the hours etc... If you have pictures of it? It can be useful for people on lawnsite to hopefully spot it around or even up for sale in other websites. Also I'm not sure if you have done it already but I would also post this on your networking site NC. Hope this helps and again good luck.
