A device for cutting vegetation comprises a base capable of being selectively propelled about a surface upon which the device sits, a turret affixed to the base and rotatable relative to the base, and one or more vegetation cutting tools affixed to the turret. The turret and cutting tools rotate together 360 degrees relative to the base as the base moves about the surface such that the cutting tools are adapted to cut vegetation on the surface.

A gardening machine is provided, including a rod portion, a controlling portion, a switch assembly and a locking member. The rod portion has a machine tool head. The switch assembly includes a controlling member, and the controlling member is disposed on the controlling portion and movable to be in a first position or a second position. The locking member is disposed on the controlling portion and movable to be in a locked position or a released position, when the locking member is in the locked position, the controlling member is restricted and positioned in the second position.

A mono-filament whip type weed cutter incorporating a pivotable shaft that enables the weed cutter to reach otherwise inaccessible weeds. The mono-filament whip type weed cutter includes two interconnected first and second trimmer support shafts. A rotating wheel connected to one end of the pivotable shaft. A power source is connected to an opposite end of the pivotable shaft. A hinge joint including a sprocket is disposed between and interconnecting the first and second trimmer support shafts. A gear lock bar secures the sprocket in place to position the first and second trimmer support shafts with respect to each other.

A vegetation trimmer having a blade guard including a drive motor and an elongated drive shaft coupled to the drive motor, the drive shaft disposed within a shaft housing having first and second ends, the first end of the shaft housing coupled to the drive motor and a power head coupled to a second end thereof. The vegetation trimmer also including a blade guard coupled to the power head assembly, and a cutting blade attached to an output shaft of the power head assembly for rotation relative to the blade guard. The cutting blade being rotatable relative to the blade guard for cutting vegetation when the vegetation trimmer is operational. The blade guard having a diameter larger than a diameter of the cutting blade for protecting the blade as well as structures near or against where the vegetation trimmer is used. The blade guard defining a plurality of shear openings.

An improved landscaping trimmer is provided. The device includes a housing having an open lower end. A motor is disposed within the housing and is operably connected to a plurality of cutting heads extending through the open lower end. The plurality of cutting heads are disposed in an offset pattern defining an upper portion of the housing and a lower portion of the housing. Each of the plurality of cutting heads is affixed to the housing in a floating arrangement. A plurality of blades extends from each of the plurality of cutting heads, whereupon actuation of the motor, the plurality of cutting heads rotate about the longitudinal axis. A handle extends from the housing, wherein the handle includes a control that activates the motor. A plurality of wheels is affixed to the housing, wherein each wheel is disposed adjacent to one cutting head of the plurality of cutting heads.

A robot mower includes a left cutter blade unit rotatable about a left vertical shaft to generate a left rotation locus, a right cutter blade unit rotatable about a right vertical shaft to generate a right rotation locus and a center cutter blade unit rotatable about a center vertical shaft to generate a center rotation locus. A portion of the left rotation locus protrudes more on a lateral outer side than the vehicle body and the left rear wheel and a portion of the right rotation locus protrudes more on a lateral outer side than the vehicle body and the right rear wheel. The center cutter blade unit is disposed between the left rear wheel and the right rear wheel in such a manner as to cover an uncut area formed due to presence of a gap between the left cutter blade unit and the right cutter blade unit.

A coupler includes a collar defining a member receiving passage. First and second lobes extend outwardly from the collar. The first lobe includes a lobe ramp surface, a cylindrical projection extending from the first lobe and radially surrounding the lobe ramp surface, and a gear extending from the cylindrical portion. A passage is defined in the first and second lobes and has a first axis. A lever arm is rotatable about the first axis. The lever arm includes a lever ramp surface. A pawl arm is movably connected to the lever arm. The pawl arm includes a portion biased into engagement with the gear teeth. A fastener extends through the passage and couples the lever arm to the first lobe so the lever ramp surface cams with the lobe ramp surface. Rotation of the lever arm in a first direction brings the first and second lobes toward each other.
