After cleaning my glasses I checked the alarm again, and it shows it is the cooling water overheat. The engine temperature gage was sitting at mid gage, upon checking the radiator I noticed that the screen over the radiator was clogged with dust and pollen from the ragweed I was cutting, I cleaned it off and the alarm went away. The first time this happened I had a audible alarm, this time I only had the light. Thanks for the information you sent, This was not in any of my paperwork or manual that I had received from the manufacturer when I purchased the tractor.
