I noticed when running a 48inch tiller on my BX-25 that the temp was almost maxed out. I stopped and let her idle down awhile as the guage dropped back into normal. I waited for another 30 minutes or so and checked oil...good to go. I checked the radiator....good to go. I opened the cover below the steering wheel and the radiator fins did have some dust/mud caked up a little, so I washed it all out. But...she still runs right up to the max temp when tilling. Anything else and the temps is fine. Is 48 inch tiller to big?
