So I have a JD 2305 that has been overheating on me. I will be mowing and after so long the blades (but not the engine) turn off and the temperature light comes on. I used to be able to mow a solid hour and a half before it would happen now it only lasts maybe a half hour. I have checked the coolant levels and they seem to be fine. I am not mechanically inclined whatsoever so I really don't know what else to do. Wanted to see get a couple opinions if I could, that way I know if its worth taking to the dealer or attempting it myself. Thanks for looking.

Welcome to the forum. Don't know anything about the Deere. One thing I would suggest would be to check the radiator for air flow blockage by grass/weed debris. Does it use an electric cooling fan and do you hear it run? The infra-red heat guns don't cost much anymore and will tell you actual temp. It could be a bad sensor. Hopefully someone will have more info. Good Luck!

Sounds like you need to check the thing out..


Oil full?

Radiator full?

Get out the garden hose and wash out the radiator fins.

The trans oil is cooled there as well.  Check the level and condition of that..

Water pump / belt OK?   tight?

If everything there checks out I'd pop the thermostat and test/replace it..


If you are unsure take it to the dealer..  That thing will cost a pretty penny to replace..
