Question about Garden
Craftsman 20 hp 42'' riding mower model 917.272911. Mower blades don't engage. Hand clutch seems okay - notice extra tension on belt when engaged, so the wire is intact. Sure the belt seems 'loosish' but it is tracked correctly and not off any of the pulleys. I can move the belt by hand and all the pulleys spin normally. Perhaps the belt stretches with age? Perhaps there is a 'tension or clutch spring' that I am not seeing. Should I remove the mower deck and then re-install, ensuring that all the springs are reset? Should I buy a new belt on the premise that belts stretch?
The fact is that belts don't stretch. They wear down on the sides, causing them to ride deeper in the pulleys and they APPEAR to be longer. Check belt "width" to see if it is less than one half inch. Most craftsman riders use half-inch (AKA: "A section") belts.
