Sean Coghlan aka @shamrockseanj on IG is the Owner/Operator of Shamrock Earthworks Ltd. in Calgary, Alberta, Canada. Over the years, his company has done a little bit of everything, but they’ve made quite a name for themselves by building beautiful custom rock retaining walls. Seriously, those guys are out there building awesome rock puzzles. Sean was kind enough to hop on a call from a job site and catch up and talk dirt with co-host Aaron Witt.

This week, Aaron and Sean went DEEP on the Dirt Talk (rock talk?) as Sean shared his love of the two-piece excavator boom, why “operator school” might be a good fit for some folks, and why a lot of folks no longer do snow removal. This was old-fashioned Dirt Talk at its best.
