Remove the metal shroud from over top the flywheel.
it might look like there is more to it than just the
screws you can see. But the metal screen in the middle
of the flywheel shroud (cover) is usually pretty thin
and you can work the shroud out from around it and
not damage the metal screen. It's pretty self
explanatory how to straighten it out again.
Then from the handle follow the cable it controls
to the engine. It will be attached to a bracket and
it controls another piece of metal that when you
squeeze the handle it pushes into yet another piece
of metal that touches the side of the flywheel and
in turn grounds out the electrical circuit and kills
the fire to the spark plug. That piece that touches
the flywheel Will get stuck inside of a slot between
the two magnets on the flywheel that's the break.
remove the screw from the break and the break will
come off that will fix it so it doesn't shut off.

In order to cut the mower off without letting
it run out of gas you need to do a little redneck
riggin.
First take the moving parts off all the brackets
I mentioned earlier. Mainly the break it's self and
the spring attached to it. Remove the arm on the
bracket that the cable controls or just take the
whole assembly off as long as it doesn't interfere
with any other engine components. The thin piece of
copper on that bracket needs to be taken off and the
wire that is attached to it don't destroy the wire.

If you don't know what the coil/magneto is it
is the sort of u shaped thing directly next to
the flywheel and should have two wires coming
out of it.
the big wire goes straight to the spark plug
leave it there.
Follow the small wire from the coil to the end.
make the wire longer by putting more on it try to
use the same gauge wire if possible.
Then you can run it down to the mower deck and
attach it somehow so that the wire doesn't ground
out when you don't want it to.
Then all you have to do is a reach down and hold
the wire to the mower deck till it stops running.
If you want a manual kill switch you can run that
small wire to the top of the handle and attach a
toggle switch to it and on the other wire on the
switch run a wire back down the handle and attach
it to the mower deck ( pre drill a hole and wrap
the wire around a screw and tighten it).
Flip the switch and it cuts off.


It's been a long time since I worked on a walk behind
mower with a mechanical brake. I remember being told
to lift the safety handle just enough so the electric
system turns off, but not enough so the brake activates.
If yours is like this, there is already an electrical
shut off.
ALL lawnmowers with safety brakes have ekectrical shutoffs.
