my 42" MTD mower with a 17hp. motor won't turn over..new starter, new
battery. when i turn the key it seems like the battery doesnt have
enough 'umph' to get the motor spinning...i have the correct cold
cranking amps for the size motor.also, am i correct in assuming that
when the motor is running that the battery is getting charged. the mower
is about 4 years old..
thanks, cj

Did you try to jump it? Getting a spark? Spark plug clean and gapped
to spec? Inspect spark plug wires? Check/change oil? Bad gas?
Following the recommended maintenance schedule?
