I put one of these on about 3 years ago and it works great.
It seems that the only time it isn't keeping me cool, is when I'm using the backhoe... and i believe its pulling hot air from the vertical exhaust, so i just turn it off.
If I'm pulling a bush-hog or using the
FEL and moving around it keeps me cool just fine.
