While not really a "mod" to the BB, this is more of an attachment. Our house sits about 800 feet off the county road and I needed a way to take the trash can out for weekly pick up. I know there are some versions of can haulers that attach to the three point but my Ballast box lives on the tractor 99% of the time and taking the BB off once a week for the trash doesn't work for me so I fab'd up this quick attach can lifter to mount on the BB. One big thumb screw holds it on and it takes about 10 seconds to mount. I lower the BB to about one inch off the ground, back in to the trash can and pick it up. So far, it has performed as needed. The only actual modification to the BB was to drill a hole for the thumb screw.
