Depends on the design. Is your mower of the cheap, crappy sort, that
requires the blade to be engaged to run the engine, or does it have a
clutch, that allows the engine to run without the blade spinning? If
it's the cheap, crappy sort, you're out of luck. Buy a less cheap
crappy lawnmower. If it's not the cheap, crappy sort, you can run the
motor without the blade attached just fine.
I suspect you've got a cheap, crappy lawn mower, and have sheared the
pin that holds the blade to the flywheel or crank. If that's the
case, pull the spark plug, tip it up so you can see the blade, and
pull the starter cord. The blade assembly should turn (you'll need to
engage the blade run thing, too).
