My _______ self propelled system doesn work any more. How can I fix it?
There are many different types of self propelled systems using cogs, chains, belts and other devices. Some, like the Honda Masters Series, use direct shaft drive and rarely give problems other than the ones already covered. It is best to check out the parts that commonly wear out first. The problem may simply be a loose belt or chain. Often cogs or the wheels they are driving may wear down enough that there is no longer any contact between them. On Lawn Boys that use friction rollers, the rear wheels may wear down enough to give this problem. On Snappers, the rubber edged drive disk may need to be replaced or the problem may be in one of the two belts.
