I have a plot that I would like to do an orchard, the problem is that there are too many stones, I was looking for solutions and the only thing I found is a stone removing machine, but I think it's too expensive for a small orchard. Is there any solution? Thanks in advance.
There is a solution, but if it's only a small area, it'll probably not be much good to you because it's a large piece of plant. There is a machine which does this used by landscapers on large areas - it's called the 612W Trommel, which is a self contained, portable, deisel powered piece of screening plant. It'll sort topsoil from stones and debris - you put the soil in one end and it spits out two separate piles, one of soil and the other of debris, from its conveyor belt.
You have a number of options depending on the size and depth of your stones and the area to be cleaned:
If the area to be cleaned is small, you could manually do it with a pick and shovel. If the stones are really big you may need a jackhammer.
But it sounds like you have a commercial size orchard, so I'll give you the options for large machine clearing.
If they are reasonably small and shallow, you could use something like a beach cleaner: There are small ones like above.
And there are large, tractor pulled varities
If the stones are large, you may need a backhoe
You're best option is to grab the whitepages and find either a rental company in your area or a contractor to do it for you. They will have the right equipment and advice for an undertaking of this size.
