My dad made a bracket that is bolted to the back of the mower behind the seat. Then I use "S" shaped hooks to hook in the handle on the trash cans and attach to the bracket on the mower. The trailer hitch on the mower is too low. The cans need to be tilted as if you were going to pull them by hand, but no lower as everything would spill out. It works great! I found that I can take two at a time to the street that way.
I tried moving these cans by hand to the street initially, but they were so heavy, I just couldn't do it. Pulling them with the mower works great! The City only charges $6.00 per month for each addtional can, so it really is a bargain.
I used a regular big trash dumpster for a year or so that had to sit by the street. With that, I had to bag my stall cleanings and still had to get them to the dumpster. It wasn't easy and the dumpster was costing me $50 per month or so. So I had it removed and went the way of the city trash containers.
