Dig Trenches for Downspout Drainage

What happens here

The presenter starts operating the Kubota KX040-4 mini excavator to dig trenches along the back side of the building. He positions the excavator carefully, then uses the bucket to dig the first segment of the trench. He mentions needing to re-familiarize himself with the controls, as he hasn't operated a mini excavator in a while. Several parallel trenches are dug to bury flexible corrugated drainage pipes for the downspouts. Excavated soil is mounded to the side of the trench. A large rock is encountered in the path of one trench, requiring extra effort to remove.

Goal: Create trenches for the buried downspout drainage system.
