AWD - It is a opposite traction motor drive. Meaning instead of just driving the two front wheels together it drives opposite ones. That allows it to not tear up the turf along with the balloon tires. And on ice it has the best traction of anything I've ever owned. It can drive on almost glare ice and not spin or slide. One time I did the driveway at my old house. It went up and around the bend like normal and cleared it all off with the brush asm. I then tried to walk up the driveway pulling the trash can. I almost killed myself as i was sliding to the edge of the "abyss" (over 100ft drop off the one side). It was pretty unbelievable at the time. I've since learned (after that one) to walk carefully when it's icy on the driveway after clearing the snow.
