My educated guess is they were getting them out of harm's way in case the town of Minneola was struck by a tornado during yesterdays warning. The emergency management of Greensburg made a similar decision ten years ago that was highly successful.
The emergency management of Minneola had ample reason for such an action. The tornado barely missed the city to the south as the illustration below shows.

Regardless, congratulations to Minneola on getting their equipment out of the path.
