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.
