The electric clutch should provide years of service. The
clutch has a buitt-in brake that stops the pulley within 5
seconds.

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.
Adjust the three nylon locknuts until space between
clutch p_ate and rotor measures .0!2" at al! three slot
