Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Thank you so much for this information. Your battery could be discharging after 4 hours, due to your charging system not working properly.
Do you have a manual pto, or an electric pto clutch?
Your pto clutch is draining your new battery, because your charging system is not working properly.
Either your rectifier regulator, or your stator/alternator is at fault.
What are the make and model numbers for your engine?
Would you like to test your stator tonight, or in the morning?
