Out of curiosity, what necessitates moving the leaf litter at all? Asking genuinely, not trying to rain on your triumph--very cool setup. Just want to mention that leaf litter provides several natural benefits as part of its ecosystem you may not be aware of:
-It provides shelter and food for ground insects that enrich soil and feed birds over winter
-Butterflies and especially moths (who also pollinate) rely on leaf litter to protect eggs from the elements over winter. We don't see nearly as many fireflies as we used to due to loss of their habitat when leaf litter is removed
-It acts as natural mulch, leaching nutrients and decomposing into additional top soil layers, as well as conserving water by moisture retention
-Energy/fuel is expended to collect and move the leaf litter, on top of negating all the above
I'd love to know if there's a unique circumstance in your situation that requires the use of collection and burning rather than natural decomp, I'm certainly open to learning something new.
