Toro 140-3912-05 Lawn Mower FWD Left Hand HOC Plate

The Toro 140-3912-05 Lawn Mower FWD Left Hand HOC Plate controls cutting height by guiding the height-of-cut mechanism, through aligned mounting points and shaped contours that translate lever movement into deck position changes. It stabilizes the adjustment linkage, while maintaining consistent spacing between components, allowing smooth vertical travel and preventing misalignment during repeated height selections across varying mowing conditions and terrain uneven grass and ground. This plate mounts on the left-hand side of the mowers front-wheel-drive deck assembly near the height adjustment bracket, interfacing with the lever system, fasteners, and surrounding structural panels that support the cutting deck framework.
