Patent number: 7823370Abstract: The wheeled weed trimmer support apparatus provides a vehicle for supporting a weed trimmer by adjustably clamping the trimmer shaft, typically above the shaft bend, in two spaced apart locations. By adjustably supporting the shaft with respect to both height and angular positioning of the trimmer head, a trimmer can be exactly controlled to allow angular cuts, more exact flat cuts, and overall desired positioning of the trimmer cutting line and/or blades. The rapidity with which such adjustments are made, especially accommodated by the t-handled tighteners, is further equally important to the adjustment capabilities themselves. The apparatus importantly provides support for a trimmer so that the load of the trimmer is not born by a user's back, shoulders, arms, and other muscles, joints, and bones.Type: GrantFiled: March 12, 2010Date of Patent: November 2, 2010Inventors: Rex J. Wiebe, Daniel Cowhick

Publication number: 20100269474Abstract: A mower 10 is provided for cutting grass where the mower 10 includes a body 12 with a mower deck 16, a motor 14, a baffle 30, and a battery 52. The mower deck 16 has a downwardly-open interior within which grass is cut. The motor 14 is supported upon the mower deck 16 and supplies a motive force for a mowing operation where the motor 14 includes at least a portion operable by electrical energy. The baffle 30 is located within the interior of the mower deck 16 where the baffle 30 bounds an area within the mower deck 16. The battery 52 is located within the interior of the mower deck 16 and is located within the area bounded by the baffle 30. In another example, the mower deck 16 and the baffle 30 are configured for substantially restraining the movement of the battery 52. In an example method, the battery 52 is installed within a baffle 30 that is secured within an interior of the mower deck 16.Type: ApplicationFiled: April 28, 2009Publication date: October 28, 2010Applicant: HUSQVARNA CONSUMER OUTDOOR PRODUCTS N.A., INC.Inventors: Nicholas Hansen, Matthew Lambert

Publication number: 20100269473Abstract: A mower 10 has a rearwardly directed discharge 24 and a handle 32 for gripping by an operator 12 walking behind the mower 10. A motor 18 powers a grass cutting operation to provide a flow of cut grass 26. A collection bag 36 has an inlet to mate with a discharge 24 of a cutting platform 16 for receiving flow of cut grass 26 there through. The bag 36 has a support 30 and a fabric enclosure 40. The fabric allows air to permeate there through while retaining cut grass 26. An opening 56 through the fabric is located on an upper side of the collection bag 36 and adjacent to the inlet of the collection bag 36. A transparent window 54 is attached to fabric and extends across the opening 56 through the fabric to permit the operator 12 to view the flow of cut grass 26 moving from the cutting platform 16 through the discharge 24 and into the bag 36 through the inlet of the collection bag 36 from an operator 12 position.Type: ApplicationFiled: April 28, 2009Publication date: October 28, 2010Applicant: Husqvarna Consumer Outdoor Products N.A., Inc.Inventors: Nicholas Hansen, Matthew Lambert, Kyle Michael Franke

Patent number: 7661255Abstract: A wheel for a piece of lawn equipment specifically designed not to produce tracks in the lawn as the lawn equipment moves over the lawn. The wheel is made of two parallel circular discs spaced apart by a center spacer. The two discs are relatively thin and thereby have minimal contact with the grass blades when rolling over the lawn. The height of the wheel and the diameter of the axle are sufficient so that glass blades on the lawn are not bent downward and extend upward between the two discs. An optional ring structure made of rubber or similar material is attached over the perimeter edge of each disc to provide greater traction and to protect the edge from damage. Located inside the wheel axle is an optional bushing or wheel bearing.Type: GrantFiled: June 9, 2005Date of Patent: February 16, 2010Inventor: William Randall Burns

Patent number: 7652766Abstract: The method for analyzing the structure of cultured hedges, equally applicable by day or by night, for a mobile, continuously-moving machine in tied or staked plantations such as vineyards, includes a system using an artificial vision system, working by transmission, which permits a detection of the shadowing of the light between one or more transmitters and one or more detectors to one side and the other of the hedge. The information generated by said shadows of light are processed by an electronic analysis system, programmed or embodied to examine the elements of the structure of the hedge.Type: GrantFiled: March 23, 2004Date of Patent: January 26, 2010Assignee: PELLENC Societe AnonymeInventor: Roger Pellenc

Patent number: 7621194Abstract: Power equipment widely used in commercial, residential and recreational settings comprises a host implement and a demountable motor. The host implement has a frame, a mounting block with a first latch component secured to the frame, a driven shaft connected to the frame with a working piece connected to one terminus and a self-locating and locking coupler on the other terminus. The demountable motor has a spacing block with a second latch component and further has a drive shaft extending through the spacing block. The drive shaft has a second self-locating and locking coupler on its terminus. When the demountable motor is positioned on the host implement, the respective couplers mechanically mate so a power from the demountable motor can be transferred to the working piece. The latch components of the mounting block and spacing block interact to hold the host implement to the demountable motor.Type: GrantFiled: August 1, 2006Date of Patent: November 24, 2009Inventor: Hillard Tyree

Patent number: 7610739Abstract: A mid-mount riding rotary mower which has a two-piece frame. The frame includes a front section that is pivotally connected to a rear section. The mower deck is carried beneath the mower between the front and rear wheels. The mower deck is attached to the front frame and follows the movement of the front wheels. The front frame includes swing arms that carry the front wheels from a first position in front of the mower to a side position for deck maintenance. In the maintenance position the deck can be removed from under the mower easily by rolling the deck forward. Either detachment of the deck or telescoping arms enable the deck to be moved out from under the mower. The deck can then be tilted up to a stable vertical orientation for maintenance of the blades.Type: GrantFiled: August 5, 2008Date of Patent: November 3, 2009Assignee: BeeLine Mowers and Equipment, LLCInventor: Vern Godfrey
