Kubota F2400 Overheating - Thoughts Please

[kthompson]

I couldn't keep my 4700 JD Tractor cool mowing grass every week.
I removed Tstat against everybody's advise, & it's ran flawless all season long

I was raised being told to do what you did. Now having mechanics of tractors and heavy equipment tell me not to, water moves too fast for proper heat transfer. But for me I have found keep it clean and have no had any real temp issue. A dirty air filter will cause more temp issues than you would think. Diesels love air.

Think I got it working now.
I did take off the new thermostat and test. Should off seen the antifreeze go all over me and garage! What a hoot.
Replaced the radiator cap.
Drained some oil, as it was too full.
Thank you everyone.

2200 hrs on Kubota F2400 front mower/72 inch deck.

Hello, hope someone can help me through this.
Between strip screws, broken bolts, etc. my mower's been down awhile. Mower Overheating (in 20 minutes) issue when on load, can idle all day long!

What I did...
Oil change, (old oil looked black)
Replaced thermostat, water pump and fan belt.
Flushed out with water, all hoses and radiator/inside & out
Washed down the whole darn thing.
Still overheating

Tractor took a trip to local Kubota dealer; what they said they did...
Fixed 4wd not engaging correctly
Flushed radiator/system?, twice.
Install 3 new blades.
Still overheating,,,,also a blade fell off!!!!!Really!

Then a friend...
Took Radiator off, went to local radiator shop, totally re-cored, re-installed.
Still overheating
Ugh

Thoughts, besides buy a new mower?

Maybe if you post this in a general tractor forum you might get more ideas. It's likely a problem common to all diesels, and this forum is fairly limited in size..

No, not a common problem with "all Diesels"!
