Product Description

Hydraulic Operation 210HP SEM 921 Motor Grader

Control System

7 position link bar with electric over hydraulic control allows ease of operation from within the cab
Optimum blade reach capability, quick DCM re-positioning for greater reach for better working on high bank side slope
The link bar is essential for extending reach capability when cutting a bank slope or back slope of a ditch
Replaceable bushings reduce service time and cost

Blade Float

Standard blade float function allows blade to lower without hydraulic pressure for increased versatility
Blade float is engaged by pushing the left and right lift cylinder controls all the way forward past the detent
Provides protection for machine and pavement during snow removal and snow plowing

Hydraulic System

Proportional Priority Pressure Compensating (PPPC) Valves contain specifically cut spools for motor grader applications, continuously matching of hydraulic flow and pressure to power demands, allowing ease of multi-function control for optimizing working efficiency
World-class variable displacement piston pump, efficiently reduces power consumption and hydraulic system heat, improving fuel efficiency
Load-sensing hydraulic system provides consistent and precise blade movement, improving finishing performance
Inboard lock check valves within PPPC, prevents inadvertent cylinder movement and potential leaks
