I'm with Dale on using wood; I like things that don't break when I use 'em, are adaptable for multiple tasks/conditions, and aren't in the way when I DON'T need 'em.
The forks in the pic are of .187" wall 2x6 rectangular tube and can pick up one end of an empty 40' container (typically 5000 lbs per end) - the gray tubes are .250" wall 2" tube and are pairs of 30", 4' and 6' long with holes in various places for 5/8" pins.
This setup was to move several piles of "brush" from a tree cleanup and "widowmaker" abatement (project also included a rented 85' manlift), the gray tubes were to keep piles from dumping on the hood of the 580B.
The loader bucket has ZERO hooks welded, instead there are 7 receiver tubes welded on and ANYTHING I can imagine just gets plugged into one or more receivers. Not too practical for a CUT, but works for a full size backhoe... Steve
