The Handy GR92P garden roller can be towed behind most ride-on mowers and lawn tractors with a hitch pin attachment. The poly drum has two drain plugs and can be filled with either water or sand. It has a 36″ / 92cm working width so is suited to the smaller end of the ride-on market. Lawn rolling is recommended in the Spring when the grass roots are active as the rolling will help identify rough areas and areas that might need re-seeding.
