Holt Cat of San Antonio, TX, took possession of the second commemorative D6 XE dozer. Before being put in the dirt in Hawaii, Goodfellow plans to feature the new commemorative dozer in the company’s 100th anniversary celebration, planned for 2021. Long-time Caterpillar customer and multi-unit Cat dozer owner, Goodfellow Bros., a fourth-generation, family-owned contractor based in Wenatchee, WA, received one of the D6 XE units. Symbolic of the medium dozer line’s long history of innovation, the D6 XE is the world’s first electric drive dozer to offer the elevated sprocket design. The third commemorative unit, a D6 dozer with four-speed, fully automatic transmission, is finished in traditional Cat yellow with special black tracks and blade. The 175,000 image appears inside the cab as well, where it is embroidered on the headrest and printed on a plaque denoting each unit’s limited-edition status.īuilt in East Peoria, IL, the first two commemorative units were D6 XE electric drive dozers, featuring a sleek dark gray and black paint scheme. However, three customers took possession of the commemorative units, which feature special decals on the fenders denoting the 175,000-unit milestone. With travel and gathering restrictions resulting from the ongoing coronavirus pandemic, Caterpillar cancelled in-person celebrations. For the first time, variable pitch angle tilt (VPAT) blades were made available to high drive dozers with the D4H and D5H models for finishing jobs faster by grading at higher speeds.Ĭaterpillar celebrated the success of the elevated sprocket design in the medium dozer class by producing three commemorative 175,000 units in May 2020. This helped to fine-tune machine balance and ground pressure for specific applications more easily. In addition to bringing many of the same large dozer advantages to the medium line, the elevated drive sprocket allowed movement of the front and rear track idlers. The Cat D4H, D5H, D6H and D7H medium dozer models were the first to feature the high drive design, and in 1987, the D8L model was added to the family. Still unique to this day for the 130- to 350-hp dozer class, the high drive design conforms to the ground better, improving durability, serviceability and performance compared to low-drive and oval track designs. It is now marking the historic 175,000-unit milestone with the production of three commemorative units. In 1985, Caterpillar expanded its elevated sprocket undercarriage concept to its medium track-type tractor (MTTT) line with the launch of the H-Series models.
