I built this lawn roller a few years ago and an old stainless steel conveyor roller from work. I drilled and tapped two quarter inch pipe threads in it and used to fill it with water. But you were always draining it in the fall so it didn’t freeze and filling it in the spring so once I got my new plasma cutter this year I blew a hole in the half inch end plate and filled it with concrete since it’s 2 1/2 times heavier than water anyway. I had this scale come on my Temu feed at 85% off for a whopping $51 Canadian delivered to my door. The roller weigh in at 685 lbs and the two cement blocks were 150 pounds each for a total of 985 pounds not bad for a little roller. As for the scale , another little tool that I’ll hardly ever use. Brings new meaning to more money than brains and I don’t have very much money so what does that tell you bahaha.
