Engine control technologies such as constant engine speed, variable-speed cooling fan, and automatic idle/shutdown systems to reduce fuel consumption.A two-pump, pilot‐operated implement hydraulic system with regeneration features (boom circuit electric regeneration, arm/ stick regeneration) to lower hydraulic flow losses and improve cycle times.Choice of boom and stick configurations (standard reach, long reach, mass-excavation) allowing the machine to be tailored to different applications.Enhanced serviceability: side-by-side radiators, ground-level service points, and improved access for maintenance. Operator comfort improvements: larger LCD monitor, optional heated/cooled seats, better visibility.
