WARNING
Operating a mower deck with loose or
weakened blade bolts can be dangerous.
A loose or weakened blade bolt could
allow a blade rotating at a high speed
to come out from under the mower
deck, causing serious injury or property
damage.
• Replace the blade bolt after striking a
foreign object.
• Use only genuine Toro replacement
parts.
• Do not lubricate the threads of the
bolt or spindle before assembly.
