Replacing winch on silage bale trailer for ATV

We've now transported over 200 silage bales with our ATV trailer.
However, we ran into a problem with the winch. It seems like the clutch has stopped working. The motor is running but the drum is not moving.
Luckily, the manufacturer has sent us a new winch, so in this video, you'll get to see us replace it and hear a review of the ATV trailer
