Production-Class Dozers Few but Mighty

摘要

Although the number of production-class crawler dozers available in North America is small (14 basic models by our count, not including special-configuration variations), the sheer size and power of these machines somehow make the category seem larger. At the "small" end of the production-class lineup are models having horsepower ratings ranging from around 300 to 350 or so, including the Cat D8T (312), Dressta TD25R EXTRA (330), Liebherr PR 756 Litronic (336), John Deere 1050K (350), and the Komatsu D155AX-8 (354). These tractors have operating weights that range from around 87,000 to 95,000 pounds, depending on how they're equipped.
