It definitely picks up stones, but it does not seem particularly efficient. One can barely see a difference between the cleared and uncleared sections of land.
Looks like it does a nice job. Really needs a side elevator to transfer directly to a following trailer. Only use rear hopper when swapping trailers. keeping those chains cleaning the field as long as possible per hour should be the goal. Expensive process probably able to be made 40% more efficient using same number of men and machines. Great machine, low impact, low maintenance costs too I would imagine.
