i just started offering leaf clean up this year, and the way ive been doing it is bagging the crap out of it with my ztr power bagger, riding the load over to the truck with the tarp laid out in the bed, and dumping the load into the tarp.
no need for a leaf loader. i mean unless you have a god-ton of clean ups lined up. just my opinion.
My set up:
-2007 Chevy 2500hd 8.1l 4x4
-7x16 open trailer
-2011 gravely zt 52hd
-21" craftsman push mower
-Stihl trimmers, blower, edgers, chainsaws.
