This video shows some work where the tilting quick coupler is very nice and handy. Here in Sweden they are pretty common on smaller loaders. I don't know if you have them over there? Haven't seen one in any pics here at the forum. http://www.youtube.com/watch?v=7GFTMbN2lL4&fmt=18
G'day Cat 920, I have'nt seen those buckets here in Australia, only on the forum, but they would be very handy on small finishing jobs like driveways, car parks and yards etc. The side tilt would be ideal for placing gravel and levelling. Rn'R.
Some more videos on machines that have Attachment bracket with angular movement. Both 15 degrees and 25 degrees http://www.youtube.com/watch?v=deO27erhq7Q - Volvo L60F with UFO 25 degrees http://www.youtube.com/watch?v=7Vca08hyUZs - Volvo L60F with Volvo 15 degrees http://www.youtube.com/watch?v=PTJ-z5eXThY - Volvo L60E with UFO 15 degrees. The last one is the same company as the one in the first link. They have bought a new machine this year.
