These bolts are designed to shearand protect the blade drive gearbox from damage ifthe blade encounters a shock load.Cutting BladeShear BoltsCutting 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 installnew bolts. Refer to CHECKING/SERVICING inthis section for Sharpen Mower Blades which de-scribes the blade removal and installation proce-dure.After reinstalling the blade, check blade timing bymoving blades through one (1) complete revolu-tion. Make sure blade tips pass clear of each other.If timing is incorrect, contact your Walker dealer.
