No idea how well it will work. I ordered it Friday, and should get it by weeks end. It has two tips, one is the big potato plow, and the other is just a steel shank. I'm planning on making 2 passes, 1st with the shank to break up the grass, 2nd with the plow to clear out the trench. I'm going to wait until after we've gotten some rain, so the ground will be a bit softer. I'll let you know how it goes.
In the meantime we have 400' of garden hose that will reach most places on the property. Even after 400' I still have more pressure than I have at the house on city water. Only bad part is having to drag 400' of hose... it gets heavy. I was thinking of buying more hoses to lay around the different areas, and just using quick disconnects to change watering areas, but that would really get in the way of mowing.
