My New Holland TC45D tractor died when I dismounted without taking it out of gear. I did, however, engage the brake. When I got back on it and took it out of gear, it wouldn't start. I've had issues with this before and have been able to shift the lever in and out of gear and then it starts. That didn't work this time. Would this be a neutral safety switch issue that bspeedy cautioned about in another thread? If so, is this something I can easily purchase and replace? If not, any suggestions?
