How do you change a friction drive wheel on a MTD blower?

To change the friction drive wheel on an MTD blower, first, ensure the blower is turned off and disconnected from any power source. Remove the cover or housing that protects the drive assembly, typically secured by screws or bolts. Then, detach the old friction drive wheel from its mounting by loosening any fasteners, and replace it with the new wheel, ensuring it is securely attached. Finally, reassemble the cover and test the blower to ensure proper operation.
