I have a ride on with B&S engine. Engine runs and mower moves in all gears but the Blades will not turn when lever moved to drive.I can move the centre bolt and the engine turns but the blade fixing stays still. The mower has been stored under a cover outside and would not start but this was due to rust on flywheel which stopped the spark being generated could something similar be at fault with the drive?

If it's a ride on, I assume the blades are driven by a belt? Is it an electric clutch? If so, the most likely problem is a dead blade engage switch. As a test, you can try connecting it direct to the battery, but access may be a problem. If it's a cable clutch, and the cable actually moves, the clutch unti itself may be faulty. Repair not possible - replacement required (it can be taken apart, but parts are not available).
