( . . . I then took the outer screen off completely and with the inner screen pulled out I looked in at the radiator fins. The fan, which is in front of the radiator, but sucks air forward, had still drawn in dirty air and had imposed a circle of dust on the square face of the rear side of the radiator. I got the vaccuum, stuck that narrow extension up in there and got the dust off the face of the radiator itself. Temp. dropped right back to normal . . .
Good Luck,

Once again, saved by Tips on TBN!!
I was mowing last week on a day with 94 deg, high humidity and noticed the temps approaching redline. It never overheated, but worried me. I knew the screens were clean. Found this tip, cleand the radiator up thorughly and temps back to normal!
Thanks again!

Hey, I know this is an old post and my tractor isn't a kubota, but I searched for my problem and this thread matches my problems and I'm in a similar area near Houston. Tomorrow, I'm taking the radiator screen off, cleaning out my radiator, checking the fan belt and thermostat. It over heated tonight as I was working. Should I do a full oil change? If the engine is running hot will it degrade the oil? I did a full oil change at the start of the season this year.

thanks

Pete

I'd say yes, change the oil if in doubt.

Shall we notice this thread has been going for more than 13 years ??

I've had multiple BX2200's overheat -- mine and another familiy member's. Yes, you need to keep the screens and radiator. etc. very clean and clear. Yes, there MIGHT be a stuck thermostat here and there. Mine (with very clean radiator, screens, etc.) gets hotter than it should (toward top end of the scale, near the red) when I mow heavy grass in high outside temps using a 60" deck.

After fooling with this issue for more than 15 years my opinion is that the water pumps are too small and do not move enough liquid per minute. They are fine most of time but do not have enough margin / extra capacity when dealing with hot weather and heavy loads over a lot of time span. I think the radiator is plenty big enough.

I'm still curious -- and get no one who knows -- if maybe the later model somewhat larger HP Kubota 3 cyl diesels have a larger water pump that would fit the older BX2200 ?

Had this problem with a BX24 with a 60" woods grooming mower (dealer said that's the size I needed), took it to the shop a few times, they changed the instrument cluster only to find out that it wasn't the problem. They never could find the issue, so I took it upon myself to try to figure it out. I noticed how close the battery was to the radiator, so I pull the battery out of the box and set it on the floor board with the leads still hooked up and went mow grass, the temperature never got over 3/4 on the gauge. I fabricated a aluminum box and relocated the battery on the left side floor board. Told the dealer what I did, said he had never heard of doing that. A year or so later I met up with the salesman at a restaurant, he told me he felt like he sold me to big of a mower.
