New Dozer's Design Aimed at Production

摘要

When John Deere Construction & Forestry began engineering a new production-class crawler dozer to replace its then-flagship 1050J model, the new machine's design centered on four key performance criteria: horsepower, operating weight, track-on-ground, and a drive system that could most effectively translate these factors into optimum pushing power. Unlike the 1050J, the new model would be completely engineered by John Deere and built in the company's Dubuque, Iowa, factory. Some five years later, when the 1050K was introduced in fall 2014, its 13.5-liter John Deere engine developed 350 maximum net horsepower. Average weight was 95,000 pounds-94,000 with a semi-U (Universal) blade and a single-shank ripper, 96,000 with a semi-U and a multi-shank ripper-and a bit less when a winch or 5,000-pound counterweight replaces the ripper. Track-on-ground was just shy of 135 inches, and a heavy-duty, dual-path hydrostatic drive system transmitted power to the ground.
