High temp. Gauge trouble?

Ok. went to tractor data, and looked up your tractor, 3 range hydro.. I cannot imagine mowing in HI range.. Hi range is for transporting the tractor on paved roads not mowing. You are IMHO loading the heck out of the engine by going slow in hi range. and you must be going slow as your tractor will go 16 mph in HI range.. I bet that is your problem. Put it in Low, or if your ground is nice and flat Med. Just what I think. I could be wrong.. but it is what I would do.

I hadn't thought about this when posted first reply, but James is dead on. I don't see in here what speed range you are using but you're better off and will run hydro much cooler running with more pedal stroke in a lower range than small amount of pedal stroke in higher range. Try dropping down a speed range and going with more pedal stroke.

The end of the saga.

My father-in-law mowed in middle range with the same result.

Tractor is under warranty. Dealer told me there had been cases of fuel injector timing causing this problem, so I rented a trailer and took it in.

The members of this forum were exactly right. My efforts to clean the radiator hadn't been aggressive enough. A better air attachment and a low powered pressure washer found quite a bit of dirt in the radiator. I plan to mow again this weekend, but assume the problem was solved.

Now to buy an electric pressure washer and another wand for the air compressor....

Glad you got it figured out.
