The new Cat 824K Wheel Dozer builds on the solid performance of predecessor models with engineering refinements in its power train, operator station and structures, and in features that enhance safety, serviceability and machine management. With a net power rating of 405 hp (302 kW) and a maximum operating weight of 74,966 lb. (34,004 kg), the 824K is available with six blade configurations ranging in capacity from 6.6 to 21.1 yd3 (5.0 to 16.2 m3) to customize it for production dozing, stockpile dozing or cleanup work.
The Cat C15 ACERT engine features an electronically controlled fuel-delivery system, an engine idle shutdown system to conserve fuel by limiting idling time, 
and a delayed shutdown feature to ensure that the engine is not stopped until operating temperatures have stabilized. Drive train efficiency, fuel economy and travel speeds are further enhanced with the lock-up clutch in the Cat torque converter, a feature that reduces both drive train power losses and system heat. Two engine options are available that meet either U.S. EPA Tier 4 Final/EU Stage IV emission standards or U.S. EPA Tier 3/EU Stage IIIA equivalent emission standards. Caterpillar, www.Cat.com
