Blade Overload Shear Bolts

NOTE: Shear bolts are not used on the DSD62 mower deck.

The cutting blade is keyed to the blade hub by two

(2)shear bolts (10-24 x 5/8 in. stainless steel ma- chine screws). These bolts are designed to shear and protect the blade drive gearbox from damage if the blade encounters a shock load.

NOTE: Tightening the 5/8-18 blade mounting nut to 60 ft-lb (81.3 N⋅m) is also important for proper shock 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 new bolts. Refer to CHECKING/SERVICING in this sec- tion for Sharpen Mower Blades which describes the blade removal and installation procedure.
