We teamed up a heavy duty dump trailer (10,000 GVW) with a Little Wonder Monster Truck Loader and a locally fabricated debris box. It fills a niche for Landscapers & Municipalities and others looking to quickly vacuum up leaf piles. Does not do well on wet leaves. This is meant for big piles of dry leaves. Not meant for the piles coming out of mower baggers etc.Those piles are too compacted. Much faster than a Trac Vac. Replaces a yard sweeper - use a big leaf blower - blow piles together or to the street and use this to load leaves in a hurry. Also known as a leaf vacuum or leaf vaccum or leaf vac trailer or vacume or leaf shredder or leaf mulcher.
