Fuel Filter
Model MT is equipped with an in-line fuel filter. Vi-
sually inspect the filter periodically, and replace the
filter yearly.
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.
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.

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.
