[QUOTE="Trizguy, post: 46190, member: 5891"] Here are some pictures of the interference. [URL='http://s1120.photobucket.com/albums/l497/trizguy/?action=view¤t=CIMG2285-1.jpg'][IMG alt="Photobucket"]http://i1120.photobucket.com/albums/l497/trizguy/CIMG2285-1.jpg[/IMG][/URL] You can see that the grapple jaw can travel past the lower hydraulic coupler [URL='http://s1120.photobucket.com/albums/l497/trizguy/?action=view¤t=CIMG2281.jpg'][IMG alt="Photobucket"]http://i1120.photobucket.com/albums/l497/trizguy/CIMG2281.jpg[/IMG][/URL] and depending on how the coupler is positioned, they can interfere. [URL='http://s1120.photobucket.com/albums/l497/trizguy/?action=view¤t=CIMG2273.jpg'][IMG alt="Photobucket"]http://i1120.photobucket.com/albums/l497/trizguy/CIMG2273.jpg[/IMG][/URL] You can see the dents on the coupler and scrapes on the grapple jaw. If the hose is allowed to rotate in toward the center, the jaw will hit the tube on the adapter and break it off. This is our modified right angle adapter.

SkidRoe, as the interference is relatively close to the pivot point, limiting the cylinder enough to stop the interference would significantly reduce the opening. I don't think that would work well for the things we do with it. If it breaks again, I will use a shorter coupler that I found at Fleet Farm. It should move the the right angle adapter back just far enough to prevent the tube from being struck. Thanks for your comments. [/QUOTE]
