When using my7740 pulling a bathing it will run hot too hot turn off air conditioner and it cools off. Radiator condenser and oil cooler are clean. Thanks for any advice

I am wondering if the belts are slipping when the A/C is running causing the fan to slow and not pull enough air thru radiator.
Just a WAG.
I think I remember belt tensioning being a problem on A/C equipped tractors.

BTW it took a second to realize a bathing was a BATWING MOWER. LOL!

How about between condensor and radiator clean?

Either belts are worn and slipping or perhaps water pump fins are worn enough that ac adds enough pull on engine to heat up.

Thanks for the correction that is supposed to be batwing

When my 6610 does this even though the radiator looks clean it’s getting stopped up between the fins
