John, it still seems odd to me that they would cut the bucket size. Not sure exactly the cubic foot capacity of the 54" but assuming it is 8 cubic feet or less, even a full bucket of wet sand or gravel does not exceed the lift capacity to full height. (Note: this assumes 120lbs/ft3 material weight and admittedly uses the pivot point capacity but on the other hand I think 8ft3 is probably more than the 54" bucket holds). If you were going to exceed the lift capacity it would be trying to lift something that doesn't want to go such as a tree /forums/images/graemlins/shocked.gif and you could make that mistake with a smaller bucket just as easily. Besides, isn't that why hyraulic systems have bypass valves (is that the correct term)?
