Safety
W ARNING
When the bagger is in operation, the blower
is rotating and can cut off or injure hands and
ngers.
• Before adjusting, cleaning, repairing,
and inspecting the blower , and before
unclogging the chute, shut off the machine
and wait for all moving parts to stop.
Remove the key .
• Use a stick, not your hands, to remove an
obstruction from the blower and tube.
• Keep hands and feet away from moving
parts. Do not make adjustments with the
machine on.
W ARNING
Debris, such as leaves, grass, or brush can
catch re. A re in the engine area can cause
personal injury and property damage.
• Keep the engine and mufer area free of
debris accumulation.
• T ake care when opening the bagger cover
to keep debris from falling onto the engine
and mufer area.
• Allow the machine to cool before storing it.
•Become familiar with the safe operation of the
equipment, with the operator controls, and safety
signs.
•Use extra care with grass catchers or other
attachments. These can change the operating
characteristics and the stability of the machine.
•Follow the manufacturer's recommendations
for adding or removing wheel weights or
counterweights to improve stability .
•Do not use a grass catcher on steep slopes. A
heavy grass catcher could cause loss of control
or overturn the machine.
•Slow down and use extra care on hillsides. Be
sure to travel in the recommended direction on
hillsides. T urf conditions can af fect the stability of
the machine. Use extreme caution while operating
near drop-of fs.
•Keep all movement on slopes slow and gradual.
Do not make sudden changes in speed, direction,
or turning.
•The grass catcher can obstruct the view to the
rear . Use extra care when operating in reverse.
3

•Use care when loading or unloading the machine
into a trailer or truck.
•Never operate with the discharge deector raised,
removed or altered, unless using a grass catcher .
•Keep hands and feet away from moving parts. Do
not make adjustments with the machine on.
•Park the machine on level ground, disengage
the drives, chock the wheels, and shut of f the
machine before leaving the operator's position for
any reason including emptying the grass catcher
or unclogging the chute.
•If you remove the grass catcher , be sure to install
any discharge deector or guard that might have
been removed to install the grass catcher . Do not
operate the mower without either the entire grass
catcher or the grass deector in place.
•Shut of f the machine before removing the grass
catcher or unclogging the chute.
•Do not leave grass in the grass catcher for
extended periods of time.
•Grass catcher components are subject to wear ,
damage and deterioration, which could expose
you to moving parts or allow objects to be thrown.
Frequently check components and replace with
the manufacturer's recommended parts, when
necessary .
T owing Safety
•Do not attach towed equipment except at the hitch
point.
•Follow the attachment manufacturer's
recommendation for weight limits for towed
equipment and towing on slopes.
•Never allow children or others in or on towed
equipment.
•On slopes, the weight of the towed equipment may
cause loss of traction and loss of control. Reduce
towed weight and slow down.
•Stopping distance increases with the weight of the
towed load. T ravel slowly and allow extra distance
to stop.
•Make wide turns to keep the attachment clear of
the machine.
•Do not tow a load that weighs more than the
towing machine.
