Scotts front wheel drive lawnmower.
Metal drive gear engages the plastic

is worn to the point it won't drive

None of my mowers look like they ever

How about the axle? Plastic is slick...
no evidence of grease there either.

Grease or no grease? Any particular kind?
Don't want to do more harm than good.

They got you to buy new wheels, and probably charged a small fortune for
them too. It's planned obselence. Rather than make DURABLE metal gears,
they use crappy plastic, knowing they will sell you expensive replacment
wheels or a new mower in a few years.....

I'd spray some silicone lube on them! Do it often!
I'd wash the beggars out once in a while - it's the crap grinding
between the steel and plastic that chews off the teeth.
