![]() In 1981 Caterpillar introduced a completely redesigned tractor with the D8L. This unit is shown with optional ROPS (Roll Over Protection System) Modular Cab, heavy-duty radiator guard, track roller guards, hydraulic control, 8S Bulldozer and multishank ripper. Improvements had been made all around the frame made thicker for more durability, a higher load handling transmission, and a larger radiator for more efficient cooling. The machine now boasted 300 flywheel horsepower provided by the Cat D342 turbocharged, fuel-injected, six-cylinder diesel engine. Some of the many other attachments available were front and rear push blocks allowing multiple D8s to push equipment together end-to-end, and a three-shank ripper for breaking up rock on a job site.Ī D8K Track-Type Tractor, circa 1974. The D8H in 1969, shown here with a standard hydraulic bulldozer blade. Peterson engineers would directly influence Caterpillar Research more than any other outside source at the time. Tested with a variety of attachments, one would eventually be equipped with a custom 22-foot wide bulldozer blade. The Twin D8 above was one of only three developed by Peterson Tractor’s Special Equipment Services between 19. ![]() With thousands of units in the field, the D8 dropped the “R” in its designation and was a top seller in Caterpillar’s stable.īefore the larger D9 was created, any demands for a more powerful tractor were sometimes met with unique solutions. Its operating weight was 50,025 lbs.īy the 1950s the D8 would have style changes to the body and the ever-reliable D13000’s horsepower was increased 150 at the drawbar. Based on a Caterpillar Seventy-Five with a little more horsepower, it wouldn’t be long before it was updated with the D13000 six-cylinder diesel engine, pushing it to 95 drawbar horsepower and 108 belt horsepower. Military versions of the D8 found their way to the theaters of World War II and provided critical support for the construction needs of American forces. Each year saw successive improvements in design, features and horsepower.Īs the construction industry grew hungry for machines to build America, the D8 tractor catered to their desires with reliable performance. This included products such as cable-operated bulldozer blades, canopies, push blocks, pipelayer cranes, and towed scrapers. As the years went by, a multitude of attachments and modifications would be made available from both Caterpillar and allied equipment manufacturers.
