Case Construction Equipment is introducing two new C Series motor graders that deliver a wide offering of new weights, horsepower and feature-driven grading solutions.
The new motor grader models — the 836C and 856C — feature a variety of standard features designed to maximize performance.
Available in both standard and All Wheel Drive (AWD) configurations, the 836C and 856C achieve Tier 4 Final compliance with Selective Catalytic Reduction (SCR) engine technology that increases fuel efficiency, keeps exhaust temperatures down and eliminates the need for regeneration.
The new models include the 836C, with 138 to 156 horsepower and an operating weight of 11,097 kg; the 836C AWD, 138 to 156 horsepower and an operating weight of 12,305 kg; the 856C: 173 to 190 horsepower and an operating weight of 15,407 kg; and the 856C AWD with 173 to 190 horsepower and an operating weight of 15,807 kg.
The 836C and 856C motor graders include several features that help simplify operation and allow operators to focus on precision and jobsite safety.
An Ergopower transmission and torque converter provide smooth automatic shifting, and a 100 per cent automatic differential lock, combined with automatic no-spin power splitting, instantly transfers torque from a slipping tire to one with more traction without any operator intervention.

The AWD models feature a creep mode that engages just the front wheels at the push of a button, allowing the machine to move at extremely slow speeds for finish grading and applications with exceptionally tight tolerances.
The 836C and 856C motor graders feature intelligent high-precision load-sensing hydraulic circuits. A direct-activated axial piston pump delivers only the required amount of hydraulic pressure where it is needed. The control valves provide pressure compensation, allowing the moldboard to be lifted or lowered in parallel, when both at full stroke, preventing unintended slope loss due to hydraulic flow/pressure differences from side to side. A high-flow floor switch allows the operator to obtain maximum output from the hydraulic circuit at any time during operation.
As well, direct-mounted hydraulic controls increase lever rigidity and reduce play in the system, giving operators positive feedback and better control from the hydraulic system during precision applications.
An A-frame drawbar provides stability due to its heavy-duty boxed frame design. The roller-mounted encapsulated circle is activated by internal gearing, which minimizes wear and increases the lifetime of its components.
Case C Series motor graders feature a high-carbon steel moldboard, and new moldboard mount and slide system, with minimized opportunity for play and fewer grease points. The moldboard is designed to pitch, tilt and move laterally, and can be expanded with available horizontal and bilateral extensions which further expand material retention capability for super fine grading applications with optional precision machine control. A hydraulically controlled five-position saddle allows operation at more than 90 degrees.
The C Series motor graders are available machine control-ready from the factory for all major suppliers of machine control technology, including Case precision partner Leica Geosystems, as well as Topcon and Trimble.
Additional options include heavy-duty tires, a dozer front blade, rear ripper and an automatic lubrication system. A heavy-duty circle drive motor and moldboard float actuation are also available from the factory.
A low-profile rear-mounted cab with wide tinted floor-to-ceiling windows and external mirrors offers superior visibility of the moldboard and surrounding area. The cab also features a standard heated air-ride seat and smooth, ergonomic controls. An available rear-view camera with 15-cm LCD monitor, as well as an advanced lighting package further improve jobsite visibility. Case C Series motor graders are designed for groundline and tandem catwalk serviceability. All maintenance checkpoints are located at ground or fender level — making service and daily maintenance as straightforward as possible.
