Can you buy or build manually-powered leaf shredder?
At my local Community Garden, we are not allowed to use power tools, but we would like to shred the piles of leaves we get each fall. Web searches for "manually-powered leaf shredders" have yielded no useful results. It seems that a hand-cranked leaf shredder should already exist somewhere. Does anyone know how leaves were shredded before the advent of gasoline and electric shredders? Any Instructables inventor interested in tackling this issue?
