Mower blade installation
Do not re-use spindle bolts which have stripped, worn or undercut threads. Make sure that the blade adapter is
seated properly on the
blade motor shaft before tightening the blade cap screw. Use a 9/16”
socket with a torque wrench to re-attach the blade to the motor shaft from underneath. It will be necessary to use
a 1-
1/4”
channel lock pliers to keep the blade adapter from turning. Torque cap
screws on motor shafts to 30 foot-pounds when reinstalling blades.
IMPORTANT:
The blade sail (curved part) must be pointing upward toward the inside of the deck to ensure proper
cutting.
IMPORTANT:
When mounting blades, rotate them after installation to ensure blade tips do not touch each other
or sides of the mower.
WARNING:
Failure to correctly torque the bolt may result in the loss of the blade which can cause serious
injury.
WARNING:
Mower blades are sharp and can cut. Wear gloves and use extra caution when servicing them.
