In addition to the already-impressive controllability of our CASE Intelligent Hydraulic System, D Series excavators have a new electronically controlled hydraulic pump, a larger control valve and a new solenoid valves. These upgrades help boost breakout force, increase lifting strength and improve responsiveness, which enables the machine to work faster throughout the work cycle. In fact, cycle times are up to 12% faster than our C Series excavators. The standard Free-Swing feature allows the carriage to spin freely while operating the boom and arm, which provides improved control when craning, pipe laying or lifting offset loads.
D Series excavators use an SCR Tier 4 Final solution that’s cleaner burning and provides up to 14% increased fuel efficiency without sacrificing power. As an after-treatment system, SCR lets the engine run at peak performance to provide full throttle response throughout the work cycle. And best yet, SCR is simple. No DPF regeneration. No new maintenance. No downtime. Just pour and go.
Comfort and Visibility
The new and improved cab provides comfort like never before. There’s more entry room and foot space. The air-ride seat is larger to reduce pressure points, slides forward and back, tilts back up to 65°, has an adjustable lumbar system and a built-in heater. An innovative armrest design adjusts independently of the console while still ensuring joysticks are always comfortably within reach. Even the pedals can adjust ±22° to suit personal preference. There’s also a Bluetooth radio and climate control system that responds to sunlight. The 7" widescreen color monitor provides a constant rear camera view for increased awareness.
When you invest in CASE equipment, you need it to last. We make it easy. D Series excavators are no exception. A Standard oil sample ports allows for quick sampling of engine oil and hydraulic oil while grouped service points, tilt-out coolers and auto-locking side panels that stay open make it easy to perform routine maintenance. We even added new handrails to make it easier to get around the machine.
