Has anyone else had trouble with the starter on a JD 4120 series? I understand this same unit is also used on skidsteers, etc that use this 4 cylinder JD Powertech engine. Mine starting acting up about (4) years ago, but I was always able to get the tractor to fire by holding the key in the start position for a while. It wasn't too bad and I kind of looked at it as an anti-theft device. (2) weeks ago it wouldn go at all however and I pulled the starter and tested it with jumper cables and a battery. It seemed ok, so I put it back on and the tractor fired again. The next time I went to use it however, no go. I pulled the starter again and this time it would not work at all with the jumper cables. The local JD dealer wanted almost $300 for a new starter but I was reluctant to buy that, not only because of the steep price, but also because the original only lasted a couple years before it started acting up. I think it is a corrosion issue because, when it was intermittant, as I held the key over, I would hear a faint "crackling" noise from the starter area as the solenoid heated up and the juice began to flow. Overal, the tractor has been great and this is the only issue over (6) years. Thankfully, I was able to find a new starter on the internet for just over $100 and it is working fine now. If I get bored this winter, I will dig into the old starter and try and figure out why it failed. I will post back when an if I find out anything.
