Check Blade Brake Clutch
System
If your mower has a BBC (Blade Brake Clutch)
safety system, the grass bag can be used to check for
BBC system deterioration. (For an additional BBC
test, refer to "Check Control Bar" section in your
operator's manual.)
1.
Install the empty grass bag on the discharge
tunnel.
2.
Push the control bar down to the lowest position
(Fig. 10).
3.
Lift the control bar to the normal "blade engaged
position, about 2" below the handle. The bag
should begin to inflate which indicates the blade
is engaged and rotating.
4.
Release control bar. If the bag does not
immediately deflate, it indicates the blade is still
rotating. Deterioration of the Blade Brake Clutch
mechanism may have set in, which could result
in an unsafe operating condition. Have mower
inspected by an Authorized TORO Service
Dealer.

Maintenance
Cleaning
To ensure best performance, the discharge tunnel plug
must be cleaned after each use. When grass is thick
and lush, clippings may collect on and around the
plug; this may make plug removal difficult. After
each use, remove plug from discharge tunnel and
clean off all debris.
Always be sure that discharge tunnel door closes
when handle is released. If debris prevents discharge
door from closing, clean inside of discharge tunnel
and door thoroughly.
1.
Stop engine and pull wire off spark plug.
Remove key from switch (key start models).
2.
Tip mower on side opposite from the spark plug.
Avoid rotating blade because starting problems
may result.
3.
Remove dirt and grass clippings that stick to
housing with a hardwood scraper. Avoid burrs
and sharp edges.
4.
Turn mower upright.
5.
Remove debris from inside of discharge tunnel.
6.
Remove screws securing belt cover (Fig. 11) to
mower housing. Lift off cover and brush out all
debris from belt area. Reinstall belt cover.
