Started mowing today. Unfortunatly my trusty reliable Wright stander did not like coming out of hibernation. Mowed three small lawns without a hitch but then on the first acre lawn of the year. Screeeeach metal on metal. I hit the blade switch but nothing happens motor dies. I pull sheild off from under motor and what do I find. Metal filings I suspect the blade clutch is fried. Anyone have this problem. If so how difficult is it to fix. Unit is well out of warrenty. 1400 hours.
