i had a dead battery, i charged it and tested the alternator. The alternator is only putting out 11 volts. After chargeing the battery, the tractor ran approx 40 minutes and slowly died. It sounded almost like it ran out of fuel. I cleaned the bulb and fuel filter and reinstalled but the tractor would'nt start. I then charged the battery overnight and put it back in. The tractor started and ran , but seemed weak, like it wanted to stall out. It again ran for 1/2 hr before i shut it down. Does this model need a full battery charge to keep it running ? Does this sound like a fuel problem ? Any suggestions appreciated.....
