Ripper Buckets UR Series perfect to be coupled with excavators weighing 1.0 to 11 tons. Entirely made of high-strength wear-resistant steel HB 400, these buckets are ideal to till and scarify very hard soils such as calcareous-marly, calcareous-sandy, calcareous-clayey (marlstone), and frozen soils. The peculiar configuration allows to channel all the thrust force to the tip of the tooth to penetrate into the most compact soils.
