I did it! the goofball that I am took the tractor earlier today, M5660SU, and without realizing that the parking brake was engaged I hit the first gear low, I felt resistance as one wheel was locked. Still, I did not realize the brakes were engaged, despite the red light in front of me on the console. I insisted slightly, not high rpm, I put it on neutral, and I finally figured out the obvious. I disengaged the brakes, I put the tractor back on forward, but this time it would not move at all, as if the gear wasn't engaged. no specific noises, it lasted less than 30 seconds and my tractor does not move. Is there any safety to prevent driving with parking brake or did I ruin my clutch?
