I saw a post on the pictures forum where the guy had taken lengths of chain and bolted to the rear of his mower. They hung down from the rear bumper and about 2 inches of each chain dragged the ground. The chains looked to be maybe 1/2 to 1 inch apart. I sent him a PM asking how it worked and he said it did a great job. I'm thinking of making one like that for my Lazer.
