context_page_description: The Caterpillar D6 track-type tractor is a medium bulldozer manufactured by Caterpillar Inc. with a nominal operating weight of 18 tons. The military versions were classified as the SNL G152 medium tractor, under the G-numbers classification system used for army tractors.
context_section_description: The rear of the machine can be outfitted with various work tools to complement the front blade:
  The rear of the machine can have large slabs of steel to add weight to the rear of the machine to aid in heavy dozing applications.
  A drawbar and CCU (Cable control unit) for pulling towed scrapers and trailed implements; later models now use hydraulics in place of the CCU to operate scrapers.
  A hydraulic winch can be outfitted on the rear of the machine for towing or pulling; for forestry work, usually with a lighter front blade as well for pushing the brush and trees about.
  A ripper with a single or multiple shanks can be added to the rear of the machine to break up hard soil or rock.
  Fitted with a linkage (three-point hitch) for use in agriculture with mounted implements like plows.
  The crawler tractor is powerful, yet small and light weighing 16 to 20 tons (18 to 23 short tons) depending on configuration. This makes it ideal for working on very steep slopes, in forests, and for backfilling pipelines safely without risking damage to the pipe.
  A low ground pressure version is also available with extra wide tracks to provide low ground pressure which allows working in muddy areas without sinking.
