If I have to plow a lot backwards with the rear blade because of deep snow, I'll sit sideways and use the pedals with my left foot instead of right. Cruise control is only set up on the forward pedal, it is just an electro magnet that hold the pedal in place until you hit the brake or switch on my tractor, but it probably wouldn't be too hard to move it over for the reverse pedal? Depends on the tractor, but some have a mid mount pto which can run a blower on the front, but that's not cheap to set up usually, or just get a front pull rear blower?
