What would happen if?

What would happen if i mounted the fan on my B7100D back wards?
Would it be better to have the fan blow trough the radiator so all the grass and dust wouldn't stick to it?
I've looked at the fan and it looks like it will bolt onto the dynamo with out any problems.
Any body tried this?

You would need a fan designed to move air the other way. If you simply reverse the fan you have it will still draw air through the rad from the front, it will be less effective because it will be acting on the wrong side of the curve of the blades. If it did work as you say, wouldn't it just plug up the other side of the rad?

You are right on reversing the fan. I held it up to the dynamo and looked at it, looked better in my mind than in the real world. LOL
Maybe a electric fan on the front of the radiator with a double pole double throw center off switch. One way blow through the radiator to help the fan when working hard, then through the switch the other way to clear the radiator when the day is done and of course center off to save battery.
I'll have to start looking for a small fan that will fit in front of the radiator but under the grill.
Maybe I'm over thinking this as I've never had my tractor get hot but it isn't always remembered to blow the radiator out.
