Ive got a SW36A-13KH walk behind that I got from my in-laws a few years ago. Worked fine and Ive kept up on maintenance. The other day while I was mowing the blades just cut off. I turned the engine off and restarted and they engaged for about 10-15 seconds. Since then I haven't been able to get the blades going. What should I be checking/ I did clean out all of the electrical connections from the yellow pull button down to the clutch with no luck. Thanks in advance.
