The TORO 140-3912-05 is a forward left-hand height-of-cut (HOC) plate designed as a direct OEM replacement component for Toro lawn and turf equipment. HOC plates are structural components that set and maintain cutting height by controlling the position of the cutting deck relative to the ground. This part is installed by professional turf equipment technicians and grounds maintenance crews performing scheduled maintenance or component replacement on Toro mowing units.
This HOC plate is intended for use in forward left-hand mounting positions on compatible Toro mowing equipment. It is a common replacement item in commercial turf maintenance operations where cutting deck components experience wear over time. Technicians servicing Toro walk-behind or ride-on mowers in grounds care or sports turf applications will recognize this as a standard deck hardware component.
Designed as an OEM-style replacement HOC plate for compatible Toro lawn and turf mowing equipment requiring a forward left-hand cutting deck plate.
Installation should be performed by a qualified turf equipment technician. Disengage the blade drive, shut off the engine, and remove the ignition key before servicing any cutting deck components. Refer to the applicable Toro service manual for deck disassembly procedures specific to the equipment model being serviced.
