Case Construction Equipment has introduced two new C Series motor graders which deliver a wide offering of new weights, horsepower ratings and feature-driven grading solutions for municipalities, as well as small-to-mid-size site prep, road-maintenance and general construction businesses. These new motor grader models feature a variety of standard features designed to maximize productivity and 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:
- 836C: (138-156 Horsepower; Operating weight: 24,466-pounds)
- 836C AWD: (138-156 Horsepower; Operating weight: 27,128-pounds)
- 856C: (173-190 Horsepower; Operating weight: 33,966-pounds)
- 856C AWD: (173-190 Horsepower; Operating weight: 34,848-pounds)
The 836C and 856C motor graders include several innovative 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 percent 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 one of the most intelligent high-precision load-sensing hydraulic circuits available on the market. 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.
Direct-mounted hydraulic controls increase lever rigidity and reduce play in the system, giving the operator positive feedback and better control from the hydraulic system during precision applications.
