Abstract
A self-propelled vibratory greensroller for smoothing a green, improving ball roll distance and striping. The greensroller has a vibratory roller and a power roller mounted in a frame with the vibratory roller in front of and parallel to the power roller. A prime mover mounted on the frame has a gear box with two power-take offs for connection to a first and second power train. The power roller is divided into right and left sections connected with a differential such that the roller sections do not scuff the green. The first power train includes, a centrifugal clutch which starts the vibratory roller into vibration at some preselected engine speed. The second power train includes a variable speed pulley providing infinite ground speed control for the power roller.

A self-propelled vibratory greensroller for smoothing a green and increasing ball roll distance comprising a vibratory roller and a power roller mounted in a frame, said vibratory roller being parallel to and positioned forwardly of said power roller, said frame supported for movement over the green on the vibratory roller and the power roller, and a prime mover mounted on the frame above the vibratory roller and the power roller, said prime mover having first and second power trains,
- said vibratory roller having a transversely extending drum rotatably mounted independent of the first powertrain in bearings in the frame and having art unbalanced shaft rotatably driven by the first power train and rotatably mounted in bearings in the drum whereby the unbalanced shaft applies a centrifugal force which vibrates the drum, smoothing the green and increasing ball roll distance,
- said power roller having a transversely extending drum rotatably mounted in bearings in the frame and divided into right and left sections and having a shaft rotatably driven by the second power train and rotatably mounted in bearings in the drum, said sections being independently rotatable with the shaft through a differential attached to the shaft whereby the sections roll at different speeds or in different directions when the greensroller is turned on the green, minimizing scuffing of the green.
