  • Split drum for a compacting work machine
    Patent number: 6837650
    Abstract: A split drum is provided for a compacting work machine and includes a first and a second drum section. A differential arrangement is operatively positioned between the first and second drum sections. Rotational power is supplied to the first and second drum sections through the differential arrangement which is connected with a propel motor. The first and second drum sections are rotated simultaneously by grounding either the first or second drum section with the propel motor. Releasing the grounding allows the first drum section to counter rotate relative to the second drum section.

  • Landscape rake with fluid controlled float capability
    Patent number: 6223828
    Abstract: An improved landscape rake including a rotatably operable rake mechanism for performing a raking function, a bucket for receiving material raked by the rake mechanism, and a fluid actuator connected to the rake mechanism operable for moving the rake mechanism relative to the bucket, the fluid actuator having a first port adapted for connection to a source of pressurized fluid for receiving the pressurized fluid therefrom for moving the rake mechanism to a position proximal to the bucket and a second port adapted for connection via a fluid path to a fluid receiver for discharging fluid thereto, the improvement including a fluid control system for the fluid actuator including a second fluid path connecting the first port of the fluid actuator with the first named fluid path and a valve disposed in the second fluid path operable for allowing fluid flow therethrough from the first port to the first named fluid path while preventing fluid flow from the first named fluid path to the first port to allow the rake mec
