I've used this mower 10 times to cut about 1.5 acres - it was doing fine until last week. Turned the key and nothing happened except voltage metet went to the negative. It had a 150 amp battery. I went to Lowes and got a 230 amp battery. Turned key and nothing. Voltage meter went to the negative just a little. I'm totally unhappy now since the thing is new 40 hours and it won't work. Could it be a fuse, a ignition switch module??? I really don't won't to spend too much money since I just spent $1400. Anyone have the same issue or could you give soem insight.
