Product Description

210HP Motor Grader SEM921

Product Description
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 the 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 the 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 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
The 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
Front Frame
Flanged box section design removes welds from high-stress areas, improving reliability and durability
Continuous top and bottom plate construction provides consistency and strength, improving front frame durability
Hydraulic hose routing minimizes exposure to damage and provides quick access for service
Maintenance-free bushings improve durability and reduce overall service cost
Large Cab
High-performance dashboard with 3 levels alarming monition system
Cab mounted on the front frame provides an exceptional view of the blade and the front axle even during articulation
