not including hoses and support angle welded to bucket. Did my own labor and welding using the old miller diesel welding machine with 6011 rods. The mounting needs to be sturdy to take the force of the 2 inch cylinder closing force without flexing the point where mounted to bucket. The base of the Grapple is a 1 inch plate that I welded to a 4 by 4 by 3/8 inch thick angle and then welded to the top of the bucket with full penetration welds all around. Looks like it worked because after moving about 20 or so large rocks yesterday there was no problems at all. Moving these rocks without the grapple would have been a time consuming process with chains and pushing since it is very difficult to get the rocks into the bucket cleanly to where it can be lifted without falling out
