The belted Challenger was the result of Caterpillar engineers’ efforts to find a use for a removable tire tread created for very large mine truck tires.  |  Ron Satzler photo

From tires to tracks: traction continues to evolve

Taking a look at how the rubber belted Challenger was inspired by a collaboration between implement engineers

Another instalment in the article series that tracks the development of ag equipment during the 100 years of The Western Producer. Take a look at images of early tractors and the obvious design differences were wide and varied as inventors searched for that perfect configuration, one that could efficiently turn engine power into usable traction.

Making the grade

Early in the testing of rubber belts, engineers had to determine if rubber belts could stand up to higher-speed travel. At that time, they were being tested on a road grader. To evaluate their high-speed performance, a grader was modified to travel much faster than normal. The 5:1 reduction in the final drive was removed, […] Read more
