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.
Cutting Blade Shear Bolts
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.
DANGER
Gasoline is extremely flammable and can
be highly explosive. To minimize danger:
• Use only an approved fuel container for
gasoline.
• DO NOT allow open flames or sparks
near the machine while performing main-
tenance or refueling; DO NOT smoke
while working with fuel.
• Wipe up spilled gasoline immediately
and completely.
