Due to the winter weather in my area, I decided to make a machine with treads, AWD, and a suspension system. Snow Tracker has many options like taking off the tracks and replacing them with tires. Other great features are a snow plow, which can be seen in 'Additional Information', and headlights. The drive system uses two NXT motors, and the steering only one. I added a PF M-motor for the snow plow and PF headlights. Check out 'Additional Information' and enjoy.
