We have our billy goat leaf loader 18 hp on an 6x12 open trailer and box on our dump insert on a chev 2500 with a mesh tarp for good air flow to pack it in and use large tarps, put a much as you can drag or hook the tarp to your mower and pull through the gate the tarp will compress to fit it through then dump it out by your loader.I did that way when i was solo for years work smart not hard.
