Illinois | We run Cat equipment and Cat has had reversible fan blades since the 60's. You push in the blade turn it 180 degrees, if they are oiled up good you can change all the blades in 2 mins. We would let the heat blow back on us until mid-day, and open the hood and reverse the blades back for the afternoon, YES IT DOES WORK!! Cat built them for this purpose.
