NOTE
• To remove the blade securely, wedge a block of wood
between one blade and the housing in such position that it
will hold the blade safely while loosing or tightening the
blade screws.
• The screw of red-painted mower blade is of inverse helical
type.
(When reassembling)
• Be sure to pay attention to how to assemble the spring plate.
• Apply grease to the spline boss.
IMPORTANT
• Make sure the spring plate is not flattened out or worn,
causing mower blade to slip easily.
• Replace the spring plate if it is damaged.
NOTE
• After reassembling the blade, check the blade slippage. If
the blade slips below blade slippage torque (66.7 N·m, 6.8
kgf·m, 49.2 ft-lbs), check the blade tightening torque and
