This my second conversion of a yard vac trailer type.Age is a factor..no more on your knees trying to lift an engine and a cast flywheel that weighs near 100 lbs to hook it up to your mower. The parts ,being true to my nature, are all used except for new steel for side braces and new bolts. I can now move this around if need be by hand without causing a hernia and it will follow the mower fine because it swivels easily. The tongue will swivel up and down several inches for uneven lawn. I left it unpainted to show all the welded spots and how it's put together..Even your wife could hook it up while you're "too busy"...
