I have a 254 it runs hot. If I run it above an low idle it over heats. I've cleaned the radiator, added an electric fan and moved the battery from in front of the radiator.
Any ideas??

How about the water pump? Could it be freezing up just past idle? Could you have a loose belt that starts slipping a higher RPM? ....

Well, the obvious things include a bad pressure cap, a bad water pump, bad thermostat, bad head gasket, loose fan belt, misaligned fan shroud. But far more common with Chinese tractors is a clogged radiator. Chaff/chad compacts between the fins, air can no longer pass through. Worst place is behind the battery. In severe cases, the radiator has to be removed for cleaning. Compressed air is the best, pressure washers can cause permanent damage.
When the engine is cold, remove the radiator cap and stick your finger in. Any oil on your finger indicates a bad head gasket. Also on a cold engine, water will settle to the bottom of the oil pan. Loosen the drain plug almost all the way - just so you get a drip or two. If water comes out first, it's another sign of a bad head gasket.

My DF254 will get hot when I'm brushhogging, but after letting it idle for a while it will cool down and usually stays well within the desired temp range. I was wondering, where you put the battery to get it away from the radiator?
I just got an electric fan from a car and was going to make the same arrangement.

Not much can be done about the battery, but if your air filter housing is up there - I might be able to help.
Also - the fins behind the radiator get clogged up with chaff and dust. If that area's not kept constantly cleaned out, the coolant goes back into the engine too hot. I use a furnace filter up front, and clean with compressed air from the backside. But if compressed air doesn't do it, you'll have to pull the radiator and clean it off the tractor.
