As you see through the video clip, Sterling Ripper has much better productivity. The conventional ripper causes much stress and shock transmitting to arm and boom, and boom cylinder was vibrating up and down at least one time during one cycle of motion with a thundering noise due to "stopper", which demages an excavator. It's hard to see and hear it from the video clip but it's clear when you see at a job site. Sterling Ripper has unique damper + link, non stopper design that eliminate such a problem.
