Am I the only one that thinks 800-1000 bucks for plastic tracks plus then ya need 6, 21" tires is insanley expensive.I don,t mean to sound like a cheapskate but I only spent 1500 for the whole machine with 22" tires 18 hp vanguard and rollbar.I thought that was agood deal for a max 4.I am getting closer and closer to attempting the softtrack design like i saw on the old amphicat brochure.Clearance is my primary concern at the moment.Looks like it will just barley fit between body depresion between wheel 1&2. Aside from that see no real problem .I do wonder if even without extensions how much more stress will this put on axels and bearings.I appreciate all your input and if you all think i'm asking for trouble here let me know thanks.
