I made a homemade roller to pull behind my ATV. I used a heavy duty plastic 55 gallon drum. I cut a hole in each end in the center of the drum. I then pushed a metal pipe slightly smaller than the hole I drilled. Then I made a frame out of leftover hardwood floor planks to connect to the metal pipe on each end and around the drum. Then I made a drop pin connection point to hook onto the ATV draw bar. I fill the drum half full of water through one of the screw caps on the top of the drum then replace the cap to hold the water in. Water will leak out where the metal pipe goes through the drum until it brings the level down when it will stop leaking for the most part. The drum half full (or so) with water and the hardwood frame weighs about 200 lbs. It works well to pull over a well prepared food plot bed to push the seed down for good germination contact.
