If the mower has an electric starter, the gear on the starter is worn. Replacement is not hard and the part (a plastic gear) is relatively inexpensive.

Normally a rusty rotor would not make a grinding noise. A grinding noise from the brakes usually indicated that the pads or shoes are worn down.

It could make a grinding type noise when moving slow. A "whirrr" type whine when moving faster. The grinding noise may change to a clunking noise when turning the wheel. Any of these noises means "fix me now or else."

They could, yes.
Don't ignore that kind of sound. Find out what is causing it and replace or repair the faulty part. A "grinding noise" can be caused by an alternator, water pump, idler pulley, heater fan motor, air pump or any of a long list of components, many of which can cause some serious problems if they seize or come apart.
Its kind of a grinding screeching metal on metal noise.
