Patent number: 7644779Abstract: A walk-behind power unit is configured to detachably mount a counter-rotating powered drum work implement on a centrally pivoted implement carrier. The pivoting of the implement carrier from a central position to either side causes the discharge of the powered drum to be located on a desired side of the work implement. The work implement can also be positioned to discharge forwardly from the powered drum member. A lift apparatus is provided to be cooperable with an associated set of support wheels to affect the positioning of the powered drum member between a lowered operative position and a raised transport position. The powered, counter-rotating drum member can be either a rotatable broom or a power rake. In the broom configuration, the lift apparatus can move the lid member, after first unlatching the lid member from the frame of the work implement, to fix the lid in an opened position.Type: GrantFiled: August 1, 2005Date of Patent: January 12, 2010Assignee: Turf Teq, LLCInventors: David J.

Publication number: 20090260841Abstract: The novel vehicle mounted edging device provides a safe and efficient means for edging grass and soil adjacent to improved surfaces. The device is attached to the remotely actuated bed of a utility vehicle and utilizes the lifting capabilities of the bed for its operation. When the disc is in the cutting position, the operator of the utility vehicle positions the vehicle near the edge of the surface to be maintained and lowers the remotely actuated bed of the utility vehicle to place the disc adjacent to the surface to be maintained. The operator then drives the vehicle parallely to the edge of the path and remove the unwanted grass. The novel vehicle mounted edging device effectively guides the utility vehicle along the edge of the path so that minimal steering is required and is oriented to enable the operator to easily monitor the edging operation.Type: ApplicationFiled: April 17, 2008Publication date: October 22, 2009Inventor: Bruce Lee Baker

Patent number: 6439088Abstract: Vegetation trimmers and methods for reconfiguring a trimmer are provided. A coupling mechanism permits reconfiguration of the trimmer between a first, e.g., trimming, configuration and a second, e.g., edging, configuration. The coupling mechanism may, in one embodiment, be used to couple a handle assembly with an extension tube. By rotating the handle assembly relative to the extension tube, the trimmer is moved between the trimming and edging configurations. In one embodiment, the mechanism may apply a biasing force to the handle assembly relative to the extension tube. The biasing force tends to bias the trimmer towards and retain the trimmer in the desired configuration. To switch the trimmer between configurations, the operator may impart a twisting force between the handle assembly and the extension tube where the twisting force is sufficient to overcome the biasing force. Optionally, a longitudinal force may also be applied before or during the application of the twisting force.Type: GrantFiled: April 25, 2000Date of Patent: August 27, 2002Assignee: The Toro CompanyInventors: Gregory B.
