Cat Track System of Cat Track Company, Toronto, Canada, on Ford F 100, 1962. Tracks were from Bombardier-type and individual brakes on each side must be added. Additional road wheels were suspended by semi-elliptic springs. Picture from book of Fred Crismon ‘US Military Tracked Vehicles’, Motorbook International Publishers & Wholesalers, 1992.
Is there any drawback to having the tracks come downhill around the tires? I want to track up a Jeep Wrangler. I've thought about making a sub-frame with a rear axle and the idlers but this would be much easier.
