getting hot after an hour of use

[AGT]

I have a JCB 8035 zts with 800 hrs gets hot after anaout an hour of use, radiator is clean on outside, fan belt is tight new thermostat, water pump is tight no leaking, anyone had similar issue thought maybe the clutch fan?
however it seems to be moving plenty of air

If the outside of your radiator is clean and the water pump is working properly, it’s time to check for any internal blockages or restrictions in the coolant flow. Another thing to consider is whether the head gasket is leaking combustion gases into the coolant. While a clutch fan issue could be a concern, it’s probably not the case if you’re getting good airflow. Make sure to pressure test the system

thanks for responding, does not seem to be head gasket issue via rubber glove test, hydraulic cooler gets pretty warm but not as hot as radiator, I guess I will drain coolant next and maybe flush radiator, just seems strange everything looks good from the outside machine is in great condition, I thought maybe they just had a weak point that was common to causing this

You should consider checking the radiator cap and the coolant mix as well. I've seen cases where pressure loss or an incorrect ratio caused overheating when the engine was under load. Also, could the heat from the hydraulic system be creeping into the cooling loop?
