Caterpillar D6

[1] The D6 started out in 1935 as the RD6, fitted with a 3-cylinder 45 hp (34 kW) D6600 engine.

This was powered by the D4600 engine of 55 hp (41 kW) (drawbar).

The dozer blade on the front of the tractor can come in different varieties: The rear of the machine can be outfitted with various work tools to complement the front blade: 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.
