| 056233000 | Hedge or plant-row trimmers | 10 |
| 20080196375 | LUBRICATION RETENTION APPARATUS FOR POWER TOOL - A gearbox is provided for a handheld power tool. The gearbox includes a housing including a recess having a wall section, a main gear disposed within the recess and including a plurality of gear teeth, and a drive gear engaged with the main gear for driving the main gear. The gearbox also includes means for retaining lubricant within the housing for improved retention of the lubricant on the main gear. The means for retaining is configured to create a localized pressure reduction within the housing during operation of the power tool. In one example, a portion of the wall section curves towards the main gear, and a localized pressure reduction is formed proximate the minimum distance between the curving wall section and the main gear during operation of the power tool. | 08-21-2008 |
| 20080196376 | SEPARATOR PLATE FOR POWER TOOL - A gearbox for a handheld power tool is provided, including a housing, a main gear disposed within the housing and including a plurality of cams attached thereto. A drive gear is engaged with the main gear for driving the main gear. The gearbox also includes a plurality of cutting members configured to engage the plurality of cams. Rotation of the main gear causes rotation of the cams to thereby cause the cutting members to move in a reciprocal manner. The gearbox also includes a separator plate attached to the housing. A portion of the separator plate is disposed between the plurality of cutting members to inhibit contact between the cutting members. In one example, the separator plate includes a leg section configured to be secured to a portion of the power tool. | 08-21-2008 |
| 20110154796 | ELECTRIC HEDGE TRIMMER - An electric hedge trimmer comprises a flat motor that is provided inside a housing and includes a rotor having a disk shaped coil disk on which a plurality of substantially ring-shaped coils are formed and arranged in the circumferential direction a motor output shaft as seen in the direction of the axis line of the motor output shaft, a magnet that generates a magnetic flux that passes through the coil disk in the direction of the axis line of the motor output shaft, a gear section that reduces the speed of rotation of the motor output shaft and has a gear section output shaft that outputs the reduced rotation, a cam that is connected to the gear section output shaft, converts the rotating motion of the gear section output shaft to reciprocating motion, and a blade section that is connected to the cam and has reciprocating motion. | 06-30-2011 |
| 20120017558 | SELF-UNJAMMING MOTORIZED TRIMMING APPARATUS, PARTICULARLY A HEDGE TRIMMER - A motorized trimming apparatus having two blades placed side-by-side, has triangularly or trapezoidally cut teeth spaced apart from each other, at least one of said blades being movable to enable the cutting by shearing of wood inserted between said teeth, and connected to a drive device. The apparatus is characterized in that it comprises a means for controlling the drive device, said control means being constructed or configured so as to detect stops in movement of the movable blade(s) and to instantaneously and automatically control the reversal of the rotational direction of said drive device and thus control the reversal of the direction of movement of said movable blade(s). | 01-26-2012 |
| 20120279193 | Method and apparatus for trimming buds and flowers - The present invention discloses an apparatus for trimming plants, in particular, buds and flowers, to remove unwanted plant material. A typical application would be to process a plant to leave only trimmed buds and flowers for use in potpourri, fragrant sashes, or as a prelude to further processing of essential oils. The invention enables faster and safer production of plant material than prior plant processing machines. The apparatus employs an original combination of a slotted metal drum and a lawn mower type cutting reel that are rotated in the same direction, but at different speeds, to create a cutting interface that shears the unwanted plant material off and then collect this debris though a novel vacuum manifold into a waste collection device. The cutting interface between the slotted drum and the cutting reel is adjustable to keep the distance between the two between 0.002 and 0.006 inches for a very sharp and clean cut. The invention includes a roller brush and sprayer system to keep the cutting interface clean, without buildup of oils and other organic plant material. The invention is built upon a frame that moves on wheels and that allows for adjustment for operation in a level or tilted configuration to best suit the processing of particular types of plant material. The manifold cover is easily removed for cleaning and for sharpening or adjustment of the cutting blades. | 11-08-2012 |

| 20110047951 | FRUIT TREE PRUNER AND HARVESTING MACHINE - An agriculture vehicle has a mobile body and an arm. The arm has a first end supported upon the mobile body and a second end movable relative the mobile body. A cutting tool is operatively supported upon the second end of the arm. The cutting tool includes a blade configured for rotation. | 03-03-2011 |

| 20120073257 | AUTOMATIC BYPASSING DEVICE OF TYING POSTS IN FRUIT-BEARING HEDGES, AND AGRICULTURAL EQUIPMENT MAKING USE THEREOF - Device for the automatic bypassing of tying posts or stakes in fruit-bearing hedges, in particular for trimming machines featuring a working head having two vertical rotating drive shafts on which are mounted two stacks of toothed cutting disks and an opening wheel. The stacks being able to assume a position where they come closer to each other and then intersect, or a position where they get further apart where the cutting disks of each stack find themselves distanced from the cutting disks of the other stack. Each opening wheel is mounted on its drive shaft through the intermediary of the speed reducer coupled to said shaft. The invention also concerns agricultural machines equipped with such a device. | 03-29-2012 |

| 20150082762 | Tree Trimmer - A tree trimming cluster of circular saws form part of an assembly on the hydraulic arm of a tractor and the assembly is adjustable hydraulically to allow the assembly to sweep from side to side, to incline in relation to the ground and to rotate with a wrist like action. In addition the whole assembly can rotate about a horizontal axis on the hydraulic arm giving an extra degree of adjustment. The hydraulic arm extends from a jib located behind the tractor driver and is capable of slewing. A variety of 4 m cuts are available which is useful for firebreak creation and powerline protection. | 03-26-2015 |
