This is for any walker owners who own a recent diesel mower. I have an '06 diesel and have had nothing but trouble with the heat gage showing it to be running about 210 degrees or right at the red line. Have had it in the shop 5 times now with this problem and their fix is to replace the gage and sending unit. I am at my wits end with this mower but my question is, has any other owners had this problem. Going to call Bob Walker tomorrow the second time and try to get this problem straightened out as makes no sense when all other water cooled walkers I am around don't have this problem. Let me know if you have had any issues and if and how they were fixed. Gage just shows hot, the mower is not actually running hot.
