last guy had the answer. The blade hub has a centering boss which when assembled correctly centers the blade so it runs true and has minimum vibration at running speed. Reinstall the blade paying attention to hardware. PR

The obvious answer to your question is to remove the blade and see why the “hub” is top-sided. Something didn’t go back on right. It is electric, turn it over and see what is wrong with it. Don’t run it with the blade installed incorrectly. Can you imagine that thing coming out from under the mower while your standing behind it? The blade should be straight and level. renpen

adjust the wheels ……..if the right side is cutting lower…..lower the wheels on the right side which will cause the deck to be raised on the right side…and hopefully you will be cutting straight…..of course if it is the left side that is lower,leave the right side alone and make the adjustments to the left wheels……(caution) if @any time the motor starts to viberate badly have a mechanic inspect it dino-duck

A quick question- when you changed the blade, did you use like a wire brush and clean all the debris off ? Grass tends to coat everything underneath, thourough cleaning and lite coat of never seize on bolts/splind pieces go toegther a bit easier. It sounds like its not tight enough and its at an angle.

An electric lawnmower doesn’t have a crankshaft.

Are you sure you didn’t accidental knock the wheels out of alignment on one side while changing the blade? Make sure the wheels are aligned with each other and that the electric motor is tightly fastened to the mower deck. If the motor is loose on one side then the torque from the blade turning could cause it to lift slightly while running. You say the hub the blade mounts to looks lop sided, but that hub spins in circles so that wouldn’t cause one side to cut lower than the other (the low side would circle around to all sides of the deck as it turns).

You can and it probably not hurt. I guess you talk of the hub the blade bolt to. It will screw off to replace, but, that may be hard to do. IF, it the crankshaft that is bent it may cause some internal wear and of course to fix require a new crank, not sure off hand what those cost. May be cheaper to use as is and buy a new one “IF” it bites the dust.
I say crankshaft, but, guess it actually the armature. snagelfritz
