Case’s new D-series graders – the 836D and 856D – feature many of the operator comfort and productivity benefits launched with the previous C-Series machines.
Both models come with electro-hydraulic joystick controls or mechanical levers, which means the operator has the ability to choose depending on preference. The electro-hydraulic system uses three-axis joysticks, which are built into multi-adjustable armrests for maximum operating comfort. The joysticks are equipped with multiple roller switches and buttons, to control various machine functions.
Powered by a Stage V six-cylinder FPT diesel engine, with Hi-eSCR2 emissions technology, the D-Series graders deliver a dual power curve, with automatic switching as higher transmission ratios are reached. This ensures maximum power is available as travel speed increase, boosting productivity.
Compliant with HVO and other XTL synthetic fuels, the 6.7-litre diesel engine features a maintenance-free diesel oxidation catalyst (DOC) with selective catalytic reduction (SCR) 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 on site. Both the two- and four-wheel drive models are available with optional 24» tyres, ideal for uneven ground conditions.
The D-Series graders feature a low-profile ROPS/FOPS cab, delivering good visibility. A reduced overall height makes for easier transportation between job sites. Full width tinted glazing and a commanding view to the front and at the moldboard, ensure optimum control, whatever the task.
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-shaped frame and central saddle provide maximum stability and versatility for the cutting edge.
The moldboard design, on a roller-mounted encapsulated slewing ring, avoids any backlash and reduces wear, while supporting high mechanical torque for maximum control. With fewer greasing points, maintenance is reduced, boosting uptime and ensuring increased profitability for the customer. The D-Series graders are compatible with most popular plug-and-play machine control systems to further boost productivity.
