:confused: Help! I have a 2003 Sears Riding Lawnmower. I thought I had a bad battery, but I have been able to jump start tractor with a battery charger. Would that be possible if the battery was bad? Mower works fine on all the flat parts of the yard, but stalls out when going uphill. Could that still be a battery issue, (due to not really having a full charge) or should I think fuel filter? Would spark plug factor in since the mower can be 'jumped'? I have cleaned the air filter. Thanks for any help--I totally appreciate it. Le
