摘要： A rotary turf mower (32) suitable for mowing irregular turf areas including a cutting system (60) which includes a plurality of cutting units (102) which are movable over the ground and each carrying at least one cutting blade (114), and a coupler (140) including a span member (144) and a pair of hinges means (150) for interconnecting adjacent cutting units (102), wherein each hinges (150) permits relative pivotal movement about a hinge axis (160), and wherein the hinge axes (160) associated with adjacent cutting units (102) are non-parallel, whereby each cutting unit may display a range of independent motion relative to an adjacent cutting unit. One embodiment of the present invention provides that the hinge axes associated with each span member are substantially directed to a virtual pivot point (184), whereby the motion of adjacent cutting units (102) relative to the virtual pivot point (184) is generally rotational. Tip-to-tip distance variation between adjacent cutting blades (114) is substantially minimized in the preferred mower by positioning the virtual pivot point (184) between adjacent cutting units (102) and substantially at the intersection of adjacent cutting planes (122). A preferred mower also includes multiple degrees of freedom between adjacent cutting units (102), wherein "pitching" and "rolling" type motions are permitted between adjacent cutting units (102).

摘要： A watercraft of the jet propulsion type comprising a steering mechanism, a throttle control mechanism, a thrust mechanism, a throttle regulator and a controlled thrust steering system. The steering mechanism has a straight-ahead position. The steering mechanism is able to rotate in a clockwise direction from the straight-ahead position to a clockwise position and in a counter-clockwise direction from the straight-ahead position to a counter-clockwise position. The throttle control mechanism is biased toward an idle position. The thrust mechanism provides jet propulsion thrust for the watercraft. The throttle regulator regulates thrust provided by the thrust mechanism. The controlled thrust steering system causes the throttle regulator to increase thrust upon the steering mechanism rotating from the straight-ahead position to the clockwise position or the counter-clockwise position. The controlled thrust steering system also causes the throttle regulator to decrease thrust upon the steering mechanism rotating from the clockwise position or the counter-clockwise position to the straight-ahead position.

摘要： A self-propelled lawn mower (2) has an engine (4), transmission (8), two drive wheels (10) and a rearwardly and upwardly extending handle (18). A pivotable and rotatable control bar (20) is mounted on handle (18). The pivotable and rotatable bar (20) provides individual or simultaneous engagement of drive wheels for ground traction, gradual or zero radius turns, and braking. Thus a single control bar (20) provides a multitude of functions.

摘要： A rotary lawn mower (2) having an internal combustion engine (8) that includes a recoil starter (17) has a zone start system (20 or 40) for supporting the pull grip (19) of the starter (17) on the handle assembly (12) of the mower (2). Zone start system (20 or 40) each includes a bracket (22 or 52) for releasably securing the pull grip (19) to one handle tube (15) of the handle assembly (12). Pull grip (19) can be easily detached from the brackets (22 or 52) and moved to a non-interfering position such that a rear bagging attachment (10) can be easily removed from the lawn mower (2) for the dumping of grass clippings.
