Why wont the blades on your craftsman lt2000 disengage?

If the blades on your Craftsman LT2000 won't disengage, it could be due to a faulty blade engagement cable or a problem with the PTO (power take-off) switch. Additionally, the mechanism might be jammed or obstructed by debris. Inspect the cable for damage and ensure the switch is functioning properly. If these components are in good condition, further troubleshooting may be needed to identify additional mechanical issues.
