As far as making compost I have been doing shredded leaf composting for a number of years - I mix some old compost with the new shredded leaves then add some 10-10-10 fertilizer and last year used horse manure mixed in.
Its about a 12 yard pile which I turn over with the FEL by dragging the top of the pile down and then scooping in the sides to the middle. I do this 2 times over the winter then in the spring add some more manure or a bag of fertilizer mix it up well and cover it with a tarp to cook. THe temp gets up to 150 or so for about a week or two then it starts to cool down. The temp kills most of the weed seeds.
At this point I just let it cook most of the summer without turning and then use to top dress beds and lawn. Turning is not really that necessary as long as the materials are well mixed and not too coarse and have a good mix of nitrogen to carbon.
So back to your question, why not use your tractor and FEL to do this instead of another tool?
