Throughout 1945, engineers performed exhaustive tests on this new product at the company's proving grounds in Illinois and Arizona, and operators tested the attachments at various locations throughout the United States. The first Caterpillar tractor with the new dozer blade left Peoria, Illinois, in 1945. Dozer blades originally came in straight, angling, and "U" shapes, both cable- and hydraulically- controlled. In early 1945, Caterpillar began developing its own line of dozer blades that met Caterpillar specifications and quality standards. A Legend Is Bornīefore 1945, suppliers designed and sold earthmoving attachments designed specifically for Caterpillar tractors. They continued to make dozers in small quantities until they were discontinued after their merger with the C.L. In 1914 the Holt Manufacturing Company, one of Caterpillar’s predecessor companies, introduced a dozer blade in front of the machine that was controlled by a rope windlass fastened to the tractor’s main frame. Their main purpose was to spread loose dirt out over a fill as it accumulated. They were made of wood and affixed to the front end of a pole that was pulled by horses or oxen. But even as late as the 1800s, dozer blades were crude by any standards. The origin of the dozer blade is buried in the past as deeply as the origin of the wheel. Hear the story of the dozer – from blade to machine – and find out why it’s a fan favorite. Today, the term also refers to the rugged machines built for tough jobs pushing dirt. Yep, the dozer part. The term “dozer” originally referred to a steel plate and an operating mechanism attached to the front of track-type tractors. Some say it may be the ultimate part provided by Caterpillar to its customers.

Check out RitchieSpecs for more info on the John Deere. The 1050K is a 95,000-lb beast with a dual-path hydrostatic transmission that, according to the manufacturer, allows for pushing through turns without losing material. John Deere’s supremacy in the agricultural equipment market is well known, but the farming equipment giant makes a mean dozer too.

The D11 is a common sight at Ritchie Bros. The D11 has since gone on to become one of the most-used ripping dozers when it comes to moving rock, earth, soil and more. Caterpillar D11 dozerĪ premier piece of yellow iron in the Caterpillar fleet, the D11 was introduced in the mid-80s to replace the D10 with a bigger track and blade, thus increasing capacity and productivity. It weighs 152,600 kilograms (336,400 pounds) and can only be transported in disassembled form. The D575A-3 SD (SD stands for Super Dozer) is a heavy construction titan used predominately by surface mine operators in North America and Australia. While ACCO might have made the biggest dozer out there, Japan’s Komatsu holds the title for making the biggest crawler tractor currently in production. As of 2012, it was reported to be housed in its birthplace of Portogruaro, Italy. It was commissioned for earth-moving work in Libya in the 80s, but trade embargoes on that country prevented its shipment. Unfortunately, this massive machine never moved an inch of dirt. It measures 40 feet in length and 10 feet in height, with a blade stretching 23 feet wide. Bellissimo! The Italian-made ACCO Super Bulldozer claims to be the largest, most massive bulldozer ever made. ![]()
