L5030 overheating

First welcome to the forum.
Need more information, my crystal ball is out for repairs at the moment.
Are you in Alaska plowing snow in the Brooks Range from the latest snow storm or in Utah moving dirt under the current heat dome? How long has it been overheating? What have you done, if anything, to determine the cause? How old is your tractor and what maintenance have you done (cleaned radiator, cleaned air filter)? etc. etc.
Not trying to be a wise guy but the more information you can provide the better the answers you'll get.

My Kubota L5030 HST started overheating last year while bushhogging my fields.
It spews steam and boiling water out the tube from the overflow tank.
Normally it runs at four to five bars on the instrument panel. Now it gets up to six of the eight bars and blows water and steam out.
Cleaned the outside of the radiator,
flushed the radiator twice,
replaced the anti freeze several times,
replaced the radiator cap,
replaced the thermostat,
replaced the water pump and still it overheats rather quickly when pulling a load like the bushhog.
Usually settles out at four bars when just low level idling or moving around the yard slowly.
It seems the next step is replacing the radiator, but I'm reluctant to put out $1,500 to $2,000 for a new one not counting labor which I usually do.
Only got about 800 hrs on the machine.
Need suggestions on what or how to test the radiators function!

Much better info!
First test is super simple, with it cold, open the radiator cap, top it off with coolant, leave the cap off and start the engine, look into the radiator for bubbles.

Is there a screen in front of the radiator that catches the large chaff? If so, have you cleaned it?
make sure your fan belt has the correct tension. tensioning that belt is part of routine maintenance. if the fan belt is loose it will over heat
