quite apparent.

terchangeable with those of previous
Lawn-Boy models.

Flywheel Height Comparison
It is important to note that two different materials
are used on compliance mower flywheels.
Flywheels for all Flywheel Brake models are made
of aluminum, but due to the need for additional
rotating weight (inertia), the Blade Brake Clutch
(BBC) flywheels are made of zinc. The zinc
flywheels are plainly marked as such to prevent
confusion. Be certain you install only the correct
type flywheel for the specific mower.
SAFETY WARNING: Flywheel Brake
(Zone and PRS) and Blade Brake
Clutch (BBC) flywheels are not inter-
changeable. The correct type flywheel
(aluminum or zinc) is critical to proper
CPSC compliance.
