BIG CHANGES T his is the year most construction equipment manufacturers roll out engines that will meet tough new Tier 4 Interim emissions standards, Caterpillar included. But the company's Build- What do Cat skid steers, compact track loaders and NFL linemen have in common? They're both getting bigger, faster and stronger. e don't know what they're feeding line- men these days but the new Cat 272D skid steer and 299D compact track loader are taking to the fi eld alongside a new pair of high performance teammates, the 272D XHP and 299D XHP. Cat product engineers say the XHP stands for "extra high performance," or "extra hydraulic power," or "extra horsepower." But whatever you call it, it means more powerful engines and hydraulics – the largest and most powerful Cat has built in this category yet. (See chart below). The base powerplant is an electronically controlled Cat C3.8 engine with a high- pressure common rail fuel system, a Cat NOx reduction system and a diesel particulate fi lter for emissions reduction. Net horsepower increases for the new D-Series models range from 5 to 18 percent W and fl ywheel torque goes up 13 to 27 percent compared to previous models. Large lift cylinders on all four machines boost lift capac- ity 19 percent, and a simpler, electrically activated quick coupler replaces the hydraulic coupler of the C-Series, elimi- nating numerous hydraulic lines, connectors and valves. Cat's new Intelligent Leveling System (ILEV) has an electronic dual self-level fea- ture that levels the load when you are raising or lowering the bucket. The return-to-dig fea- ture takes the bucket back to a preset angle, and the work tool positioner allows attach- D-Series skid steer/track loader specs Model 272D HP (net) Weight 95 272D XHP 106 299D 95 299D XHP 106 8,404 lbs. 3,200 lbs. 9,304 lbs. 3,600 lbs. 10,898 lbs. 11,647 lbs. *35% tipping load/ 50% tipping load EquipmentWorld.com | May 2012 45 2,975/4,250 lbs. 3,185/4,550 lbs. ments to return to a preset angle even after the machine has been repositioned.
