Got tractor from late father-in-law"s estate, so no answers from previous owner. Was disking with her the other day, hot day, pushing it pretty hard, running pretty deep with a 15 foot disk.
Got to looking at fan, and it is curved with the curve (dished side) facing forward. Thinking curved side should be rearward, right? Looks like I can remove bolts holding fan, reverse, and bolt it on other way.
 
I think if the fan pulls air thru the radiator and out over the engine, then it facing the right way for a farm tractor.
 
No the fan is the correct way around. The curved blades create lift, which increase the efficiency of the fan blade. It blows much better than a fan with flat blades.
 
Hi,
If the curved side is to the front and the direction of rotation is sending the air forward then it certainly looks like it is wrong. I have no information to suggest that it should be fitted any other way. The fan will draw air through the radiator and expel it over the engine, thats why radiators invariably get blocked at the front. Also later UK 100 series tractors had cladding which effectively covered the sides of the engine and ducted warm air to the driver. If the fan was fitted the other way round this would be of no use. The photo of my 165 shows the correct fitting.
