For the guys who have the walkers and Z's that have hoppers that catch the grass in the back and dump from the drivers seat, how and where are you dumping these? Do you have a collection box on the trailer, as I cannot imagine it is tall enough to dump in the back of a truck. What about dumping on-site? In most of my cases they have dumpsters that are too tall to dump into. I know not everyone bags grass as I don't at every site or everytime depending on the time of year. But at times I must bag or do leaf clean-up.
