Here is some video of a 2010 Ox playing here in Alaska on some snow cover glacial silt hills. It was very slick but the climbing was impressive. We have the track extensions on the hubs as we are getting ready to put the tracks on for the winter but wanted to try it out on the tires in these conditions. We had all the power we wanted just ran out of traction however some the it was very very steep. We will go out in the same area with the tracks and compare but it might be a bit scary because it should climb about anything we throw at it with traction the tracks provide.
Enjoy
