Hi there, First post on a message board. I was plowing snow with my 2014 HDX 700. Pushed a pile of snow and when I backed up I heard a loud scraping / screeching noise from underneath the box in the transmission / clutch area. What would be the most likely problem. I stopped and it won't go into gear after shut down. When I tried to restart it made the same loud noise. I'd really value some advice. I can't even move it to load it on a trailer. Thank you.
