“One of the original taglines to promote the early high drive tractors was ‘Beyond Known Capabilities,’ because these units set a new standard for efficiency, productivity and ease of operation,” says Wes Holm, chief engineer, Caterpillar medium tractor products.

Whether it’s telematic data from equipped machines that gives you better insight into your operation. 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. Caterpillar OEM Solutions provide partial machine configurations, including bare chassis, systems and first-fit components, to create specialty machines and unique equipment to meet your project needs. This helped to fine-tune machine balance and ground pressure for specific applications more easily than oval track machines.

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 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 (100 to 250 kW) dozer class, the high drive design conformed to the ground better, improving durability, serviceability and performance compared to low-drive and oval track designs. bulldozer caterpillar, bulldozer machine, Bulldozer.
