Ever had a battery goes so dead your machine's stator can only put out enough power to keep the motor running ? and not the mowing deck ? I ran into this yesterday. My garden tractor battery was so dead that I couldn't even get a audible click when turning the key over. So I put it on the trickle charger and gave it a bit. Then I threw it into jump start mode and cranked on it.. NOTHING.. so I broke out jumper cables and hooked it up to my truck, that got things spinning.. so I let it run about 5 minutes then started mowing (released the emergency stop button on the dash to activate the mowing deck) that lasted about 5 minutes and then the deck disengaged and stopped. I turned the key off and then tried restarting the mower, absolutely flat dead. So I pulled my truck in the yard and re-jump started it, then back to the garage. I put my marine battery on it and bingo ! all systems were a go ! So this was a learning experience for me. With a dead battery you can jump start however the mowers stator is not putting out enough power to run the mower and keep the clutch activated for the mowing deck. This was on the Intek 24HP B&S MOTOR.
