The electric clutch should provide years of service. The
clutch has a built-in brake that stops the pulley within 5
seconds. Eventually, the internal brake will wear which may
cause the mower blades to not engage, or, to not stop as
required. Adjustments should be made by your nearest
authorized service center/department.

Make sure attachment clutch and ignition switches are
in "OFF" position.
