What is the best unit for suburban backyard with moderate brush cleanup annually. Have large trees, branches, twigs, few leaves. I try and compost everything in 30 X 15 vegitable garden. Currently using rotary mower as "poor-man's shredder" and it has taken a beating over the years. Can't seem to burn off larger limbs and branches fast enough (live in warm, So. Calif, no need for fireplace fires). Any suggestions
