Why does my Bx2680 start to over heat after about 2 hrs running...coolent level is good...radiator screen is clear.?? Any thoughts

After it cools off remove radiator cap and check coolant level there. Recovery tank may have bad hose and not working right.
Over working tranny? Doing work in high range when low is better choice?
Since it's a BX, is plastic hydro fan OK? (underneath tractor)

I'm not super familiar with your cooling system. Few suggestions:
-First and most importantly, make sure the coolant level is correct - check radiator when cold.
-Is the radiator cap which pressurizes the system in correct working order?
-Does the tractor have a thermostat which opens and allows coolant through the system? If so, is it in correct working order?
-Make sure you are getting airflow through the radiator. Make sure radiator is not caked with grass clippings, etc. Make sure if there is a fan to draw air through the radiator that the fan blades are centered within the shroud and the blades are proper length.
-Is the cooling system missing any important shrouds or air deflectors which are pivotal to proper airflow?
-Make sure no hoses (Lower or upper) out of the radiator are caving and not allowing flow.
-Make sure proper antifreeze is being used. There are many different types and they don't all work for the same application.
If all of the basic items above check out OK, I would then start to consider:
-Is the water pump working properly
-Is the radiator plugged

Get yourself a laser thermometer. Can be had quite cheap anymore. Check top and bottom radiator hoses to see what kind of temps you're running. Bottom should be lower than top, as that's the radiator doing it's job and dissipating heat from the coolant.
My BX2360 occasionally reads hot when it's really not. Have had the temp gauge read Full-on "HOT" within 5 minutes....engine temp was only 120*F or so.
I pull the spade connector off the temp sending unit in block, clean and add a little dielectric grease. Seems to make it more reliable for a while.
Not saying this is your issue...just something to check:

BX RUNNING HOT...Or Not?
Comes up often, and often they can run hot. Usually gummed up radiator. Started mowing other night and within ten minutes I see this: Holy smokes!! (Not what I really thought)!! But wait a minute...haven’t run long.... Shut her down. Get laser thermometer. Top radiator hose is 135F...

^^ this has happened to me as well. And to confirm it, i shut the tractor off, and turn it back on and the gauge snaps back to normal Ive seen it twice in two years.My BX2360 occasionally reads hot when it's really not.
