Case has unveiled a new D Series long reach (LR) excavator that offers increased dig radius, depth and precision in deep or long-distance digging applications.
The new full-size CX350D long reach excavator provides increased operating performance in applications that require long-distance bucket reach and precision.
The new model features an elongated boom and arm and additional counterweight for increased digging capabilities in deep or long-distance digging applications, while providing the same improved responsiveness and control of the D Series.
With an operating weight of 40,000 kg, the CX350D LR features a 268 hp Tier 4 Final diesel engine and up to 24,500 foot-pounds of bucket digging force.
The extended arm and boom provide a maximum digging radius of 18.6 metres, and a maximum digging depth of 14 metres.
The CX350D LR is built with a selective catalytic reduction (SCR) Tier 4 Final solution that provides improved fuel efficiency without sacrificing power. SCR allows the engine to run at peak performance throughout the work cycle. As the engine operates without a diesel particulate filter (DPF), there’s no DPF regeneration or associated lifetime service costs.
As part of the Case D Series lineup, the CX350D long reach offers more standard features than previous Case excavator models.
All Case D Series excavators include a heated air-ride seat, Bluetooth radio, rear and side-view cameras, free swing for improved craning, laying or lifting of offset loads, oil sample ports and an easy control pattern selector and an easy pattern selector for the operator’s preference of ISO or SAE controls.
Intelligent Hydraulic System
As well, D Series excavators achieve faster cycle times through a new electronically controlled pump, a larger control valve and multiple advanced sensors. The features combine with the Case Intelligent Hydraulic System and its four integrated control systems to make the best use of the machine’s hydraulic power and momentum, resulting in faster cycle times and improved fuel efficiency.
The four systems that make up the Case Intelligent Hydraulic System are: Boom Economy Control (BEC), which reduces rpms and leverages gravity during boom down and swing; Auto Economy Control (AEC), which lowers rpms during idle and automatically shuts down the engine after a preset idle time; Swing Relief Control (SWC), which regulates hydraulic swing power at the start of the swing; and Spool Stroke Control (SSC), which adjusts hydraulic pressure to optimal outputs and minimizes unneeded operation functions.
Using improvements to the Spool Stroke Control system, the CX350D LR reuses hydraulic fluid — when possible — to automatically increase cycle times and efficiency. The operator experiences a more productive machine without losing the precision of the machine’s controls.
3 working modes
The CX350D LR excavator also provides the operator with three working modes – speed priority, heavy and automatic – that help the machine conserve energy.
The arm and boom of each D Series excavator have been built stronger for greater durability and to support the added power of the machine. The undercarriage is built with thicker steel and a new single-slope design that reduces dirt accumulation and eases cleaning.
The D Series long reach excavator features a fully adjustable operator station anchored by a standard heated air-ride seat and joystick controls that allow for smooth performance.
The long reach excavators also feature best-in-class cab space, excellent visibility, and a pressurized and viscous (fluid filled) cab mounts keeps noise and vibration down.

A standard Bluetooth radio gives operators hands-free functionality that further improves the operator experience.
Standard rearview and side view cameras feed a 15-cm widescreen monitor that also provides operators with real-time access to important performance parameters, including fuel consumption, operating hours and machine information.
Each D Series machine is available with an optional LED working light package — that is three-times brighter than halogen — providing improved visibility and jobsite awareness for operators.
The LED package includes eight LED lights (three front, two rear, one on each side and one on the boom). An optional Case Max View display package includes an additional side-view camera that allows the 15-cm in-cab monitor to display a 270-degree aerial view of the surrounding worksite for improved safety and visibility.
