Buy 3 new self-locking nuts, $.75 each. Yours has lost the plastic
locking ring.

i have a craftsman 3 blade ride on mower and one day after mowing a
field of tall grass i turned the blades off, the center blade just
fell off the shaft onto the ground.
i just thought it a fluke wierd thing, so i sharpened the blade and
took the other two blades off to sharpen and balance them as well,then
put them back on.
excited to mow with sharp blades i started her up and took off for the
field.it worked perfectly.
i mowed the field and when finished i shut the blades off only to find
the
end blade had droped off the shaft.
i thought perhaps i had not tightened the bolt enough, so i torqued it
down as much as i could.
just to find that on a trial blade run it does the same thing. quite
frusterating-
i cannot find anything on lawnmower blades just falling off.
does anyone have any suggestions???

Asked Sears?? Mounted wrong side up??
