is in the locked, neutral position and blade engage knob
is down.

to allow access to blades.
NOTE: If necessary, raise the mower by placing on a lift
or using a jack and jack stands to gain access to the
blades.

If raising the mower to access the blades, make sure the
mower is properly secured and the parking brake is set

ous personal injury.
