Hello. I am new to the forum. I recently purchased a 2021 UForce 1000. The first time I used the winch I pulled an old ford tractor out of a container. The UForce was in Park and while pulling, I heard a loud pop and the UForce now rolls freely when in park. Everything seems to be working fine other than the machine rolls when in park. The emergency brake is what we rely on now to make sure it does not roll when on a hill. Any ideas. The machine is still under warranty. Thanks in advance for all responses.
