    Do not do this, get a heavy duty fan clutch and lower the blade a little when on the highway. When I had a straight blade I had put on a curved/formed snow deflector and it actually worked wonders to get airflow over the blade. I posted pics and a little blurb about a while ago.

    the electric fan will not keep up at highway speeds. I had a 454 with 2 fans and they couldn't keep up
    do the clutch upgrade, or don't go on the expressway

    do you lower the plow and angle it when on the highway?...when getting a hd clutch for the fan be sure that it is one!...fins extend to the end and squared
