These bolts are designed to shearand protect the blade drive gearbox from damage ifthe blade encounters a shock load.Cutting Blade Shear BoltsNOTE: Tightening the 5/8-18 blade mounting nutto 60 ft-lb (81.3 N⋅m) is also important for propershock load protection. It is important to not over-tighten the mounting nut since this defeats (over-rides) the function of the shear bolts.If these bolts shear, remove the blade and install newbolts. Refer to CHECKING/SERVICING in this sec-tion for Sharpen Mower Blades which describes theblade removal and installation procedure.DANGERGasoline is extremely flammable and canbe highly explosive.
