The rear of the machine can be outfitted with various work tools to compliment the front blade.

This configuration is typically used in fine grading applications. A Variable Pitch Angle and Tilt ('VPAT') is a straight blade which has the ability to change the pitch of the blade (leaning forward or backwards) as well as the ability to hydraulically raise, tilt and angle the blade.

A 'S-U' combination blade which is shorter, has less curvature, and smaller side wings.

A Universal Blade ('U-Blade') which is tall and very curved, and has large side wings to carry more material.

A Straight Blade ('S-Blade') which is short and has no lateral curve, no side wings, and can be used for fine grading.

The dozer blade on front of the tractor can come in different varieties: The D6 ? with 185 hp of gross power and an operating weight of 18 tons is in the middle of Caterpillar's track-type tractors.This was the first D6 with Caterpillar's elevated drive sprocket undercarriage, known as the CAT Hi-Drive system. The Hi-Drive D6H was introduced in 1986 along with 3 other H-Series track-type tractors.They were replaced after 60,000 had been built in 1959 with the D6B.This was replaced by the D6 8U (60' narrow gauge) & 9U (74' wide gauge series in 1947.The D6 was fitted with a 6 Cylinder engine as used in the Caterpillar D5 9M.This makes it ideal for working on very steep slopes, in forests, and for backfilling pipelines safely without risking damage to the pipe.Ī low ground pressure version is also available with extra wide tracks to provide low ground pressure which allows working in muddy areas without sinking.Ĭaterpillar first introduced the D6 in 1941 with the 4R & 5R series to replace the Caterpillar RD6. The vehicle is powerful, yet small and light, weighing 16 to 20 tons (18 to 23 short tons) depending on configuration (recent models). The D6 is primarily used to move material short distances or through challenging terrain.

The Caterpillar D6 track-type tractor is a medium bulldozer manufactured by Caterpillar Inc.
