The D2's weight ranges from about 7,420 to 8,536 pounds (3,366 to 3,872 kilograms), depending upon the year it was manufactured. The base frame of this model of tractor is a crawler, and it is equipped with five forward gears and one reverse gear. in their factory in Peoria, Illinois, USA. The Caterpillar D2 was manufactured from 1938 through 1957 by Caterpillar Inc. It was introduced in 1938 and was the smallest diesel powered track-type tractor manufactured by Caterpillar. The Caterpillar D2 is an agricultural tractor manufactured by Caterpillar. However, two undercarriage configurations will still be available in standard and LGP or low ground pressure.Caterpillar D2 compact crawler tractor (built from 1938–1957) at the Belvoir Castle Steam Festival 2007, Belvoir Castle, England. Now, part of the naming change we discussed earlier is dropping the XL designation that existed on the older models. And so it’s a just a better overall combination when we go to these newer high tech engine and transmission solutions.” Undercarriage and footprint unchanged “So we’re able to use a little bit smaller displacement engines, get the horsepower we need from it very economically, primarily with some great machining and new designs that allow that machine to operate for a lot longer period of time than what some of these former engines used to. “But today with the control systems we have that becomes less critical,” Fritts explained.

Today with the control systems that we have on both engines and transmissions, the two can communicate together so much better than what we had in the former days where you had a manual transmission and you had to depend on engine torque, for example, to change with the transient loads the machine or the vehicle may see. “It’s very similar to the automobile industry or truck industry. And I would just like to address that a little bit,” Fritts says. “I know sometimes there is some concern with the smaller size of an engine changing displacement. Thanks to the new engine however, the new dozers can deliver fuel savings of up to 10 percent. The D1 remains at 80 hp, the D2 at 92 and the D3 at 104 hp. Though Cat has switched from its C4.4 engine to the new C3.6 engine, these new small dozers retain the horsepower ratings of the machines they replace. That provides quite a bit of commonality for servicing.īut emissions and fuel economy are two other major factors in the switch to the C3.6 for Cat’s smallest dozers. That Cat C3.6 engine is also notable because Cat is using it across a wide range of smaller equipment, including most of its Building Construction Products lineup of compact machines including backhoes, compact wheel loaders and more. The new Cat C3.6 engine provides quite a bit of space savings found through its more compact packaging and thanks to a bit of rearranging Cat engineers did with the engine components. Plus, Cat says that lower hood design was made possible by a new engine for this part of the dozer range. Cat says this change provides 30 percent more visibility both over the hood to the blade and to the operator’s peripheral views. Specifically, the machines feature a redesigned hood that slopes lower toward the ground. In addition to being adorned with the new Cat logo and model badges, now complemented with that new hexagon design, these dozers also feature styling changes. And while there’s a little concern there, in the long run, after we get through this adjustment period, I think it’s going to be a lot simpler for everyone to understand what size Cat dozer they need to do the work.”Īnd while we didn’t anything new to talk about with the D4, there’s plenty of new stuff to talk about with the new D1, D2 and D3.īeyond all the new model names, the next big change with these three new small dozers is their new look. So that’s how we wound up with this very simple model nomenclature, which basically from a D6 down, we’ve moved the numbers down a little bit. There’s a lot of heritage in the “D” nomenclature. We thought it was the best and that it preserved our brand equity. “One thing we really do at Caterpillar, we listen to our customers and our customers were telling us we needed to try to simplify our nomenclature somehow,” says Joel Fritts, Caterpillar product application specialist for small dozers.
So, Cat changed the name to the D4 for obvious reasons. So, going back to the new D4 we mentioned earlier, since the new naming system for dozers only allows for one model per size class, that means the D6K2 would have fallen between the D3 and D5 in terms of size and capability. So if you grab one of these, you’ll be buying a bit of history.
A little bit of triva for you, the D1 is an all new model name for a Cat dozer.
