Unplugging a Clogged Unit

Conditions such as grass that is too long or too wet or
cutting at too fast of a ground speed could cause the
blower and the discharge tube to become clogged.
If any part of the collection unit becomes clogged
while in operation, follow these procedures to safely
remove the clog from the unit.
WARNING
High speed discharge can cause injury or
death. Do NOT run blower without discharge
tube, hood and bags installed and latched.
Before cleaning, discharge tube or blower,
disengage PTO, stop the engine and remove
the key.
Never place hands into blower housing to clear
jammed objects or plugged blower. Blower may
rotate when object is removed.
If the discharge tube is clogged:
1. Park the machine on a flat, level surface.
Disengage the PTO, engage the parking brake,
turn off the ignition and remove the ignition key.
2. Loosen the lower clamp (with knob) (A, Figure 39)
securing the discharge tube to the blower outlet
and remove the discharge tube from the blower.
3. Shake the discharge tube to loosen the clog from
the discharge tube.
4. If the clog will not loosen use a suitable tool, such
as a broom handle, to clean the clog out of the
discharge tube.
5. When the obstruction is cleared, re-install the
discharge tube onto the blower outlet and secure
in place with the lower clamp (with knob).
