Garden rollers come in many styles. There are lawn rollers that you can push in front of you or pull behind you. There are also lawn rollers that hook up to a riding lawn mower. These are the most popular---especially for lawns that have steep inclines. A riding lawn mower needs a hitch in order to attach a lawn roller to it, which most do. With a few materials it is easy to attach a lawn roller to a riding lawn mower.
Drive the riding lawn mower to a smooth, level surface. This will ease in the installation of the lawn roller.
Position the lawn roller behind the riding lawn mower. The lawn roller will have two bars with a hole in it that slides over the mower's hitch. Slide these bars over the mower's hitch so that the holes all line up.
Place the 3/8-inch by 4-inch long bolt through the holes and screw the nut onto the bottom of the bolt. Tighten by hand.
