Muffler
Remove the muffler by following these steps:
1. Remove the six nuts and bolts (three on each side)
that hold the rear bumper in place using a pair of 1/2”
wrenches. See Figure 2.1.
2. Slide the bumper out from between the frame, the
fuel tank bracket on the right and utility bin bracket on
the left.
3. Remove the two nuts that hold each exhaust pipe to
the cylinder head using a 13 mm wrench.
See Figure 2.2.
4. Remove the muffler and exhaust pipes.
NOTE: The exhaust pipes are welded to the muffler. The
pipes and the muffler are serviced as one assem-
bly.
5. Clean and remove all gasket material from the cylin-
der head (and the exhaust pipe if they are being
reused).
6. Using new gaskets, install the muffler by following the
previous steps in reverse order.
NOTE: Tighten the exhaust nuts to a torque of 120 ft lbs
(14Nm).
NOTE: When installing the bumper, insert all six bolts
before tightening them. Otherwise the bumper will
bind and the holes will not line up.
7. Test drive the mower in a safe area before returning it
to service.
