sharply in confined places you may damage the
attachment or other property.
Trimming
Always trim with the left side of the mower. Do
not trim with the right side of the mower because
you could damage the bagging tubes.
Cutting Height
For optimum bagging performance, set the deck
height-of-cut to remove no more that 2 to 3 inches
(51 to 76 mm) or 1/3 of the grass height, which
ever is less. Cutting off more than this will reduce
the capacity of the vacuum system.
Cutting Frequency
Cut the grass often, especially when it grows
rapidly. You will have to cut your grass twice if
it gets excessively long (refer to Bagging Long
Grass).
Cutting Technique
For best lawn appearance, be sure to slightly
overlap the mower into the previously cut area.
This helps reduce the load on the engine and
reduces the chance of plugging the blower
assembly and tubes.
Bagging Speed
The bagging system may plug if you drive too fast
and the engine speed gets too slow. On hills it may
be necessary to slow the machines ground speed.
Mow down hill whenever possible.
As the bagger fills, extra weight is added to
the back of the machine. If you stop and
start suddenly on hills, you may lose steering
control or the machine may tip.
• Do not start or stop suddenly when going
uphill or downhill. Avoid uphill starts.
• If you do stop the machine when going
uphill, disengage the PTO. Then back
down the hill using a slow speed.
• Do not change speeds or stop on slopes.
Bagging Long Grass
If the grass is ever allowed to grow longer than
normal, or if it contains a high degree of moisture,
raise the cutting height higher than usual and cut
and bag the grass at this setting. 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
In 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 cause damage to the mower
