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.
