[AT] "First" diesel crawler w/ Blade

[jfgrant]

In November of 1924 Holt Tractor was developing tracts on equipment. As 
early as 1919 tracks were being installed on steam engines. Hole and Best 
were the first to develop track machines. They were competitors. Most 
development occurred in Calif. Holt became Caterpillar in later times. There 
is a good Cat site. www.caterpillar.com
