In February 2025, YG Machinery successfully exported to Poland a hydraulic drum cutter attachment for excavator, where it was mounted on a CAT 320 excavator for a demanding excavation project.

How a Polish Contractor Conquered Tough Rock Excavation with a YG Hydraulic Drum Cutter
In the rugged landscapes of southern Poland, Piotr Kowalski, an excavation contractor, faced an uphill battle—literally. His company, Kowalski Earthworks, had won a bid for a road tunnel project near Kraków, but there was a problem: the terrain was full of hard limestone and reinforced concrete structures from old foundations.
Piotr was looking for a precise, low-vibration solution to keep the project on track. Then he discovered YG Machinery’s Hydraulic Drum Cutter. And he contacted YG’s team for recommendations. Within a few weeks, he had his brand-new YG Drum Cutter Attachment For Excavator delivered and mounted onto his CAT 320 excavator.
The results? Game-changing.
- Cutting speed doubled, allowing his team to complete excavation ahead of schedule.
- Minimal vibration meant no collateral damage to nearby structures.
- Fuel consumption dropped, reducing operating costs significantly.
Piotr was so impressed that he later ordered a second drum cutter and a new hydraulic pile breaker for an upcoming demolition project in Warsaw.
“This machine saved my project. YG Machinery didn’t just sell me a drum cutter attachment—they gave me an edge over my competitors,” Piotr said, smiling as he watched his team power through solid rock with ease.
Thanks to YG’s technology, Kowalski Earthworks is now bidding on larger-scale excavation projects—a future Piotr wouldn’t have imagined before.
