1999 Argo Bigfoot. I have the Argo Plastic tracks on it. The Bigfoot comes with 25 inches tires but, the tracks don't fit unless you have the 22 inch wheels. There isn't enough clearance in the wheel wells. I will be doing lots of maintenance on this machine. It has a Briggs and Stratton motor 18 horse Vangaurd. It does float which is why it will go on my boating channel.
