ENGINEERED TO PROTECT.
Dropping a bucket is every operator's nightmare. Our S-System couplers feature redundant safety systems to ensure that never happens, even in the event of hydraulic failure.
Hydraulic Lock Valve
Built-in check valves maintain pressure even if a hose bursts, preventing attachment drop.
Front Pin Lock (FPL)
Mechanical technology ensures the front axle is secured before the rear engages.
Visual Indicator
Clear green/red indicators visible from the cab confirm when the coupler is fully locked.
