I just bought a new 1023e tractor a few days ago. Today was the first day that I got to put it to the test. Used my bucket for moving limbs and piling them up. Did that for about 3hrs all in all pretty light work. I did not have any issues with overheating and the tractor performed great. I decided to mow some of the taller grass that I did not get to before last fall because my mower had a bearing go out. The grass was not really that tall also pretty thin and the grass was dead since it is February so easy to mow. After about 30 to 45 min I get engine overheating warning so I shut it down. It had a little debris on the filter in front of the radiator to took out screen and cleaned it also knocked a little grass off of the outside of the front of tractor. Could here what sounded like bubbling from the radiator. tStarted back up set to the correct rpm for mowing and 15 mins later overheated. Water level and coolant is fine Turned it off for a min then started back up still hot lowered rpms to lowest and let idle. After about 30 seconds the gauge started going down pretty fast like the thermostat opened up so I though it may be sticking. It's been mid 70's today and going to be mid 60's tomorrow and I'm going to try it again tomorrow but there should not be an overheating issue expecially in this cool weather. Has anyone else had an issue like this tractor has 4 hrs on it.
