I have a 2518 cub cadet that I'm having electric pto issue and starter issue. My problem with the pto clutch is it will only engage sometimes and if the mower is hot the clutch will not engage until it cools off. My starter solenoid problem is when I go to start the mower hot or cold it will click every time I turn the key after a few turns it will crank. Is this just a battery issue or do I need to replace the pto clutch and or solenoid?
