Lawn-Boy 39-7840  Square Key

This repair part is made by the Original Equipment Manufacturer (OEM) to return your equipment to peak performance levels after normal use. When installing it, remember to do so in a well lit and ventilated space, while taking proper safety precautions like eye protection and chemical-resistant gloves as appropriate. Using only Genuine OEM parts, the same that would be used by an Authorized Dealer performing a warranty repair, will ensure the optimal performance and prolong the life of your equipment.
