Two of my four legged friends are the start point of my compost process. Daily cleanup yields a number of pounds of manure. I make piles of the stuff for weeks, adding coffee grounds, grass clippings, fallen fruit, straw, just about anything that's green or brown. Once the pile is about the size of one of my bins (6 x 4 x 4) I start mixing with my old tractor, dragging the pile back and forth always moving toward the bin. By the time I get there, which isn't far, maybe 10 feet, my pile if quite mixed, I push it into the bin and just let it finish. It does get very warm at times, so I will mix again if temps get up in the 140 area.
