These 2 videos give a quick example of what my stump grinding machine does. I use a blade in some cases to push the mulch back into the hole that is created. The hole can be filled with soil and seed if you wish to allow for new grass to grow where there once was a stump. This job site does not require me to go very deep. It is to remove the trip hazard and eliminate the eye sore. Like I mention in my other post, each job is tailored to what you need done. My machine has a remote control option so I can view the progress from all angles and it keeps me at a safe distance to observe the machine working.
