Scotts front wheel drive lawnmower. Metal drive gear engages the plastic gear molded inside the wheel. Plastic is worn to the point it won't drive and I'm replacing the wheels.
None of my mowers look like they ever had any grease there.
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.
