Hi, I have a john deere x740 mower. It started overheating

Resolved Question:

Hi, I have a john deere x740 mower. It started overheating after 2 hours of use at the weekend. I checked oil and it was ok, and coolant all ok, drive (fan belt) working. I then found that it was clogged with dry grass and dust in between the radiator, so cleaned that out completely. However its still overheating. I got on it yesterday when it was cold and just let the engine run. after about 3-4 mins the temp needle started moving and just continued all the way round to red, so I turned it off. I have read the troubleshooting part in the manual, and checked all the things it says to stop overheating, but it still is. can you help me please ? many thanks, Dave

This sounds like the engine thermostat.
Because of the quick heating up.
Sometimes they will after being overheated, stick closed and not allow water/antifreeze to pass by.
It should be located on the engine head where the upper radiator hose connects to the engine head.
