I have a New Holland LT185b compact track loader that just died in after working her for about 2 hours lightly. Boom is up and I can't lock it out because the safety pin is halfway covered. I was going in reverse to dump a bucket and the dash lights flickered and she went off fast. I heard and smelt plastic smoldering under the rear engine access hatch but it went out as I got a fire extinguisher. It would not start or give me any electrical or power at all when I tried to restart. Any tips for securing the boom somehow for safety? Or for the running problem? This is my first construction machine and I use her for light ranch and gardening chores. Thanks!
