An roller assembly for attachment to a lawnmower. The roller assembly generally includes a tow arm having first and second links. The first link is configured to be supported at least indirectly on the lawnmower frame. The second link is connected to a shaft mounted with one or more rollers. A spring is disposed between the first and second links and configured to bias the second link downwardly relative to the first link, thereby biasing the rollers against a ground surface. The roller assembly further includes a quick connect assembly for rapid attachment and detachment of the roller assembly to the lawnmower. The roller assembly yet further includes latch assembly configured to hold the second link and shaft of rollers in a raised position relative to the ground surface.
