Query: Lawn Roller

I received my order just as I expected. Instead of using water, I filled the lawn roller with sand. It took a lot of sand and afterwoard was rather heavy. It seemed to have worked fine, but the lawn tractor I have to pull the roller was heavier than the roller. It was a good purchase, but I cannot help but think that I should have gotten a roller that was heavier. The size of the roller did not allow a noticable difference in the yard it was purchased to flatten.
