The history of the Challenger brand began more than 125 years ago in North America with the experiment of two American inventors - Holt and Best, who were the first to use a steam engine on agricultural tractors. In the distant 1889, D. Best presented the world with the first steam-driven tractor, but it turned out that such a machine is slow and has too much weight for working with soft fertile soil. It was then that the second inventor, Holt, proposed a solution to the problem by increasing the area of contact between the tractor and the ground and replacing the wheels with caterpillars. The first tractor appeared in 1904.
The modernized Holt tractor was tested and became the beginning of the history of the new trade mark Caterpillar. (Service Manuals PDF page) The researcher officially registered his brand and launched its own production at the Holt Manufacturing Company.
Meanwhile, the son of the first inventor Best, Clarence Leo, continuing his father's business, worked on creating his own caterpillar tractor and in 1913 succeeded. Then there was a tractor under the brand Tracklayer, assembled at the Leo plant - C. L. Best Tractor Company.
A new chapter in the history of Challenger tracked tractors began in 2002, when AGCO acquired the rights to the Caterpillar brand, since then the range of equipment produced under the Challenger brand has expanded significantly: self-propelled sprayers, trailed tillage and seeding equipment, etc. Most modern and high-performance Challenger tracked vehicles are equipped with fully integrated Autoguide automatic steering and telemetry systems, which allows them to more efficiently build the work of agricultural enterprises.
