CASE has launched D-series graders for construction: the 836D and 856D. The machines feature intuitive moldboard control, powerful Dual Power engines and a range of after-sales solutions.
Control and Operation
The D-Series graders are equipped with a low-profile ROPS/FOPS cab for visibility. A reduced overall height facilitates transportation between jobsites. Full width tinted glazing and a commanding view to the front and at the moldboard support control.
There is a new touchscreen display, for all machine and maintenance info and to provide a monitor for the rear-view camera. This customizable screen is located on top of a redesigned front console. A second console to the right-hand side of the cab incorporates the ignition key, the new electronic hand throttle, a cup holder and USB charging ports. On the left-hand side of the cab there is a storage compartment, which features a rubber strap and net.
CASE
The new Grader comes in both electro-hydraulic joystick controls and mechanical levers, which means the driver has the ability to choose depending on preference. Both machines come in standard with a heated and air-suspended seat. The electro-hydraulic system uses three-axis joysticks, which are built into multi-adjustable armrests. The joysticks are equipped with multiple roller switches and buttons, to control various machine functions.
These joysticks also provide control of all moldboard operation, steering options and TwinLift control, which allows the operator to control both lift cylinders from a single joystick.
Performance on the Jobsite
Powered by a Stage V six-cylinder FPT diesel engine, with Hi-eSCR2 emissions technology, the CASE D-Series graders deliver a dual power curve, with automatic switching as high transmission ratios are reached.
Compliant with HVO and other XTL synthetic fuels, the 6.7-liter diesel engine features a maintenance-free Diesel Oxidation Catalyst (DOC) with Selective Catalytic Reduction (SCRoF) exhaust after-treatment system. An Ergopower transmission automatically delivers smooth shifting between gears, with all-wheel drive models having a creep mode for compaction work, reducing the need for additional machines. Both the two- and four-wheel drive models are available with optional 24-in. tires.
D-Series graders can be tailored to the application with a choice of different moldboard widths, moldboard extensions, an overload clutch, a five-tooth ripper, additional counterweights and LED working lights. An A-shape frame and central saddle provide maximum stability and versatility for the cutting edge.
CASE
The CASE moldboard design, on a roller-mounted encapsulated slewing ring, avoids any backlash and reduces wear, while supporting high mechanical torque for maximum control. The D-Series graders come ready to install a range of plug-and-play machine control systems.
Graders come with a CASE SiteWatch subscription – a tracking and fleet management tool, allowing customers to remotely monitor their equipment in use. Fleet managers can use geofencing to increase security and monitor unauthorized equipment use. With CASE SiteConnect this telematic transfer is enhanced by directly alerting dealers about machine performance and operating conditions, allowing proactive maintenance, repairs as well as preventive service.
