Abstract
A powered lawn mower of the type particularly adapted for mowing greens on golf courses and having a powered vertically adjustable reel cutting unit is converted into a greensroller when a vibratory roller unit is substituted for each reel cutting unit. The vibratory roller unit has a drum, an unbalanced shaft and a framework. The unbalanced shaft is rotatably mounted within the drum and the drum is rotatably mounted in the framework. When the greensroller is powered over a golf green, it provides a fast, smooth, consistent and somewhat firm playing surface without scalping or otherwise compromising the health of the grass.
