Big digging muscle meets hallmark CASE hydraulic precision and responsiveness to deliver one of the most powerful, efficient and reliable excavators in the CASE D Series lineup: the CX300D. A large and intuitive workstation provides operators with excellent comfort and visibility to the work area. And the CX300D is protected by CASE ProCare — giving you peace of mind to invest in your business knowing that CASE and your local CASE dealer supports you with preventive maintenance, SiteWatch telematics and more. This model is also now available with OEM-Fit 2D and 3D machine control solutions from your CASE SiteControl certified dealer.
Productivity
In addition to the already-impressive controllability of our CASE Intelligent Hydraulic System, D Series excavators have an electronically controlled hydraulic pump, a larger control valve and 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.
Fuel Efficiency
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 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.
Serviceability
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 handrails to make it easier to get around the machine.
