Blade Overload Shear Bolts
NOTE: Shear bolts are not used on the DSD62
mower deck.
Fuel Filter Location
IMPORTANT: Replace the fuel filter only in a clean
area where the fuel line and connections will not be
contaminated by any dust and dirt.
The cutting blade is keyed to the blade hub by two
(2) shear bolts (10-24 x 5/8 in. stainless steel machine
screws). These bolts are designed to shear
and protect the blade drive gearbox from damage if
the blade encounters a shock load.
DANGER
Gasoline is extremely flammable and can
be highly explosive. To minimize danger:
• Use only an approved fuel container for
gasoline.
Cutting Blade
Shear Bolts
• DO NOT allow open flames or sparks
near the machine while performing maintenance
or refueling; DO NOT smoke
while working with fuel.
• Wipe up spilled gasoline immediately
and completely.
1. Close the fuel tank shut-off valve.
2. Expand and slide clamps on either side of the
filter away from filter and pull fuel lines off filter.
3. Replace filter.
4. Open fuel tank shut-off valve.
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 overtighten
the mounting nut since this defeats (overrides)
the function of the shear bolts.
If these bolts shear, remove the blade and install new
bolts. Refer to CHECKING/SERVICING in this section
for Sharpen Mower Blades which describes the
blade removal and installation procedure.
