I'll start an appropriate thread.does it work well? I am thinking about getting one. I wish it didn't cut on some random pattern because at least on your picture I can see the cut/path lines.
It works really well. The reason you do see those cut lines is because at the time of that photo it had been operating for all of 30 minutes (e.g., also in the pic are our trencher and homemade cable-layer for the 2,300 feet of periphery wires we had just finished emplacing). Now, some weeks later, its cuts are invisible.
