Why are my mower blades not spinning?
A badly worn or stretched belt can slip, causing the blades to turn very slowly or not at all. This is relatively common, as belts tend to stretch over time and need to be replaced regularly. A seized shaft on a spindle can cause the pulley not to rotate, and this can cause the belt to snap.
Why wont my blades engage on my John Deere mower?
There could be a problem with safety switches. On most newer model lawn mowers, the brake has to be disengaged or off for the blades to operate. You also have to be sitting on the seat to engage the PTO, so the seat switch may be malfunctioning.
Should my lawn mower blade spin freely?

How do I know if my PTO clutch is bad?
Simple test would be to remove the mower deck belt from the PTO pulley and try to engage the PTO. If it doesn’t stall, the clutch is not your problem. If it does stall I would guess you’ve had a bearing fail in the clutch. The other thing to check is the seat switch if it’s still enabled.
