Front mount snowblower

hello everyone. He is my problem....I'm trying to hook up a front mount pto driven snow blower to the rear of my tractor. I need to know if there is a way to reverse the rotation of the pto shaft or if there is a converter that I can get for the snowblower gearbox to enable me to hook it up to my tractor.

If you haven't already figured it out, a reverser off a field chopper, or chain drive to an idler sprocket with a 3rd sprocket runnning on the back side of the chain driving the blower or if you've got enough power/hydraulics and $$ a hydraulic motor on the blower.
Going to put one on my 399 Massey this year.
Here's a photo of a front mount Cub blower I put on my AC B. Too bad I didn't know Cub PTO runs backward of everybody else. Best little snow sucker you ever saw!
