Nice machines and work. That looked like some nice timber, hopefully you were able to get the logs to the mill. Also pretty sure you know but much easier to get the stumps out while pushing em over, my 8 ton and most in this class have most pushing power when tracking forward.
This was really my first experience with an excavator. Not very confident with winds that day and right near house. Actually back on the same job now for stage 2 of this project nearly a year later and it's a whole different ball game now.
