The Caterpillar D8R is a track-based crawler tractor. Because its weight is distributed over the large surface area of the tracks, the crawler tractor can operate on soft surfaces not suitable for wheeled vehicles.
The Caterpillar D8R is 21 feet long, including the blade. It is 8.7 feet wide at the widest part of the tracks and has a total of 10.5 feet of track in contact with the ground. At 11.5 feet tall, it offers 1.7 feet of ground clearance.
The Caterpillar D8R has a six-cylinder diesel engine. The 14.6L engine produces 305 horsepower at 2,100 rpm. The engine is both turbocharged and aftercooled.

The Caterpillar D8R has an operational weight of 73,850 pounds. It has a fuel capacity of 165.1 gallons.
The Caterpillar D8R is capable of 6.8 mph going forward. In reverse, it is capable of 8.6 miles per hour.
The tracks exert 13.1 pounds per square inch (PSI) on the ground under the tractor. They use a standard 22-inch shoe and have 44 shoes per side. There are eight track rollers per side and the track has an 8.5-inch pitch.
