Glacial rocks? What size?
I have glacial rocks, and some are too big (car size) but many are the bushel basket size (on average). I used to dig them by hand and know that isn't the way one wants to do it for very long. I probably move out about 100 rocks on average every two years. They poke up and I have to do it again or risk hitting them with the mower deck.
I moved first to an old beam from a one-bottom horse drawn plow. Kept one handle on it, hooked a chain to it, and I would guide it down behind a rock with one of the boys driving the tractor. One gets some real thrills and jolts doing it this way, but rolled out a lot of rocks using that tool.
Then I picked up a 1-tooth sub-soiler for the 3pt. I could work my way down easier and grubbed a lot of rocks that way. Then use the bucket to roll them out, pick them up and bring top soil back to fill the hole.
Then, by accident, I found out my forks worked fantastic to dig them out, and often to even carry them away. I can point them straight down, work down around the rock and carefully pry them out. If close enough together, the rock cradles between them for moving to another location.
So, my No. 1 choice is the forks. /forums/images/graemlins/wink.gif
If I had a backhoe, I'd probably use it for rocks.
(If you are talking smaller [1 -4" size] rocks, then a Harley Rake, or equivalent, works well for me, windrowing the rocks so they can be picked up with the bucket. There also are field rock pickers that might work for you, depending on the condition of the 'lawn').
