Then cut and bag the grass again using the lower, normal
setting.
Excessively long grass is heavy and may not be propelled
completely into the bagger. If this happens, the tube and
blower may plug. To avoid plugging the bagging system, mow
the grass at a high height-of-cut, then lower the mower to
your normal cutting height and repeat the bagging process.
Bagging Wet Grass
If possible, always try to cut grass when it is dry. Wet grass
can cause plugging.
Reducing Plugging
To avoid plugging the bagging system, reduce ground speed
and mow the grass at a high height-of-cut, then lower the
mower to your normal cutting height and repeat the bagging
process.
Signs of Plugging
As you are bagging, a small amount of grass clippings
normally blow out the front of the mower. An excessive
amount of clipping blow-out indicates that the bagger is full
or the tube is plugged.
Bagging Blades
For most mowing conditions, the standard high lift blades will
provide the best bagging performance.
The Toro Atomic blade is recommended for bagging leaves
in dry conditions. In dry dusty conditions, the medium lift
or low lift blades will reduce dust and dirt blowout while
providing effective bagging air flow.
Contact an Authorized Service Dealer for the proper blades
for different mowing conditions.
Curb Climbing and Loading
Always lift the deck to the highest position when loading the
machine on trailers or ascending/descending a curb. Leaving
the mower in a lower position can damage the machine while
loading and going over a curb. If a curb is higher than 152 mm
(6 inches), cross it at a sharp angle with the deck fully raised.
Use extreme caution when loading the machine onto a trailer.
