I like the idea's, I had one today too, Id like to share it with u all, might be a little off the wall and won't work, But a mechanical way of picking rocks beats trying to hire people or friends to pick rocks,
I was thinking of getting a heavy truck axle 1ton to 3 ton, taking narrow gauge rail road track an cutting it into 3 foot lenghts. On top of the axle would site a square frame, welded to the axle sort of like a trailer frame only the frame would start right on top of the axle instead of the middle. The track would be welded onto the frame and pointing into the ground at an angle like a pitch fork, a shallow angle. I would have to rig up some sort of hitch on the out side of the frame going around the train track to a point where it could have a hitch for a tractor to hook onto. I would drag this unit in the ground behind the cat or tractor, hopfuly the rocks would traval up up the tracks to the top of and fall back into an old ore car bucket I got from an old gold mine. The bucket is perfet because it hinges in the middle, If I plan it right i can have the ore bucket leaning over a little to let the rocks fall in easier then when it full I could use hydrolics to tilt the bucket back and dump the rocks out the back. Its realy crude, id have to have some realy strong steel to with stand the load of the rocks and being dragged in the ground,
I wonder if there is some way of utilizing the rear end of a truck frame, how do i make the rocks go up hill??
just some thoughts what do u think?
