Loading a Hay Bale onto the Unroller

What happens here

The farmer backs the bale unroller, attached to his ATV, toward a round hay bale. He dismounts to remove the two spikes from their storage position on the unroller. He then backs the unroller further, carefully aligning the spikes with the center of the hay bale. Once aligned, he reinserts the spikes, pushing them firmly into the bale to secure it. Next, he engages a hand crank on the unroller to lift the bale off the ground and into its transport position. The video shows the entire process from various angles, including close-ups of the spikes engaging the bale and the winching mechanism.

Goal: Securely load a round hay bale onto the unroller for transport.
