The AGCO catalog shows 2 different thermostats for the WD45 ... a 160 and a 180. Just wonderin what what kind of experiences other folks might have had. Seems like the 160 would be better for longevety --less stress on cooling system etc, but maybe the 180 would be better for cleaner burn on todays fuels? Any thoughts?

I install the highest temp thermostat in my rehabs as they are "hobby tractors". I believe that the higher degree thermostat is better for the hobby tractor engine. Most hobby tractors do not get much running time and/or enough work to get the engine, tranny, and gearing warm enough to evaporate the condensation in the lubes. The old tractors have a very large radiator which provides considerable capacity for extended operation under heavy loads.

If you are using the tractor for extended periods frequently under high loads, and the engine gets above 180-190F (and your radiator is clean), then the lower temp thermostat is for you.

Thanks. I do use it for plowing and disking, but also for lighter stuff like brushhogging. I flushed the radiator last year but beyond that I don't know how clean it is.

160 for alcohol antifreeze, 180 for permanent antifreeze and a pressurized cooling system. It would be better for combustion efficiency to run even hotter but the oil can't take it and water boils too easily, even under pressure.

180. If the tractor is in good running order and the cooling system in good shape you should have no problems with heat. I have a LP D-17 with a 180 t-stat and it runs between 190 and 200 loaded and that is in Texas summers.

You havee to clean out the outside of the radiators with compreede aair or water periodically to get it clean.

You want the 180. In the owner's manual on my CA it states that MINIMUM engine temp is 170 for gasoline and 190 for tractor fuel.
