How do you change the blade on a Toro 21" self-propelled mower
If your push lawn mower is not working as well as it used to work, you might be thinking about replacing it. Before you purchase a new push lawn mower, check your current mower's blade. Over time, lawn mower blades grow dull and no longer cut grass as effectively. If you take your lawn mower blade to a hardware store that offers a blade sharpening service, you can usually get the blade resharpened for a small fee. With a newly sharpened blade, your old lawn mower could be working just like new.

Most likely the blade is bent.
A standard 22-inch push mower typically requires a 22-inch blade. However, it’s important to check the mower's specific model, as some may require a different blade design or type. Always consult the owner's manual for the correct specifications to ensure optimal performance and safety.

If it is a push lawnmower, probably (Although I have seen one with an electric starter). If it is a riding mower, probably not. On a push mower, the hub where the blade is bolted onto is attached to the engine driveshaft via a keyway and a fastener (nut). Therefore, the blade is not driven by a pulley. On the contrary, on a riding mower, the blades are usually driven by a belt that transfers motion from the engine shaft pulley to another pulley that spins the blade(s).
Having a blade on or off the mower will make no difference to whether or not it will run. If you took the blade off because you hit something and it needed to be replaced then more than likely you broke your flywheel key and that will keep it from running
if this is a gear transmission, it should roll in neutral unless the transmission is damaged or the brake is frozen, hydrostatic transmissions have a release mechanism for moving them when engine is off.
loose blade, bent crankshaft.... remove sparkplug cap so mower won't start & spin blade at moderate speed with hand & if it stays level around whole mower deck the crank is not bent. youtube user (davidsfarm) would likely know whats wrong. the piston rod might be loose.
