Install Castor Wheels; Installing Push Arms - Toro 78478 Operator's Manual

Warning
Without the grass deflector, discharge cover, or
complete grass catcher assembly mounted in place,
you and others are exposed to blade contact and
thrown debris. Contact with rotating mower
blade(s) and thrown debris will cause injury or
death.
Never remove the grass deflector from the
mower because the grass deflector routes
material down toward the turf. If the grass
deflector is ever damaged, replace it
immediately.
Never put your hands or feet under the mower.
Never try to clear discharge area or mower
blades unless you release the bail and the power
take off (PTO) is off. Rotate the ignition key to
"OFF." Also remove the key and pull the wire
off the spark plug(s).
