My favourite tool had to be the deep diver ( subsoiler ) It stayed on the farm. I had a need for drainage ditches on my Island lot. The new deep diver is like a double sided plough. Drag it behind for an instant ditch. Stops dead when it hits a solid root. Meanwhile the six foot blade needs welding after hitting and shoving rocks. I managed to spread many yards of stored dirt as part of my landscaping. Spread seed and now it is raining at just the right amount. All is good.
