A hedgetrimmer having a blade assembly that converts between a straight blade configuration and a curved blade configuration. The blade assembly includes a support bar for securing a pair of cutting blades. The support bar is made up of a plurality of rotatable support links allowing the support bar to curve. A switch assembly includes a rigid wire fixedly secured to the support bar. The rigid wire extends and retracts, moving the support bar between its straight and curved configuration.

The reciprocating cutting blade apparatus includes: a pair of reciprocating cutting blades disposed to overlap one another in a thickness direction; a support member configured to reciprocably support the reciprocating cutting blades in a longitudinal direction; and an adjustment mechanism configured to adjust a gap between the reciprocating cutting blades on a lower surface side of the support member. The adjustment mechanism includes: a screw hole provided in the support member; an adjustment screw including an external thread configured to threadedly engage with the screw hole through long holes provided in the reciprocating cutting blades; and a nut configured to threadedly engage with the external thread protruding from an upper surface of the support member to fix the external thread to the support member. The external thread protruding from the upper surface of the support member includes an operated portion configured to be operated to turn the adjustment screw.

A bush pruning apparatus adapted for use in combination with a tractor or similar vehicle, wherein the apparatus is mounted to the tractor by a frame that allows the position of the cutting blade relative to the bush be pruned to be freely independent of the position or tilt of the tractor, such that changes in elevation or ground surface encountered by the tractor are not transmitted to the cutting blade to adversely affect the height of the cutting blade.

A plant trimming guide apparatus, including a plurality of guide blades made of a resilient material, and a flat collar having a length, a width, an attachment surface, and made of a resilient material. Each of the plurality of guide blades has a pivot end that is secured pivotably with a common securement pin, and an opposed based end, with the plurality of base ends attached to and extending from an attachment surface of the collar, in a series along the length between the first end and the second end of the collar. Securing the first and second ends of the collar into a formed ring with the attachment surface facing outwardly causes the guide blades to extend radially from the common pivot ends and bend semi-spherically to the base ends, forming a spherical trimming guide.

A leafy plant trimmer that is operable by a single person has a basket that is rotated in relation to a stationary sling in order to trim plants placed within the basket. The basket and the sling are housed within a trimmer body that is pivotally connected to a pivot stand. The trimmer body can be rotated between a product loading position for filling the basket and an in-use position for trimming the plants within the basket. A motor housed in the trimmer body spins the basket through a drive shaft. The motor is electrically connected to a timer such that the trimmer can be operated at designated time intervals. Trimmings are expelled from the trimmer body through a debris hole and collected below. A first receptacle attachment and a second receptacle attachment are positioned below the trimmer body and allow a receptacle to be positioned for collecting the trimmings.

The invention relates to an adjustment device for automatic adjustment of a spacing between a first and a second cutting blade (21, 22; 51, 52), the first and second cutting blades being mounted so that the first and second contact surfaces (31, 32) are in contact with and parallel to each other; wherein at least one of the first and second cutting blades (21, 22; 51, 52) is displaceable to produce a cutting action between first and second cutting edges (23, 24). The first and second cutting blades are connected by at least one adjustment device (28; 50; 90) arranged to maintain the spacing between the first and second planar contact surfaces. The adjustment device (28; 50; 90) comprises a connector (34; 64; 79; 84; 94) extending through a recess in the respective first and second cutting blades at right angles to the first and second contact surfaces and arranged to guide the movement of the displaceable cutting blades relative to the other cutting blade; a first stop (33; 63; 102) fixed to one end of the connector (34; 64; 79; 84; 94) and arranged in contact with the outer surface of the second cutting blade; and an adjustment means (40; 70; 80; 100) located at the opposite end of the connector and arranged to apply a pre-tensioning force on the outer surface of the first cutting blade (21; 51) and maintain the first and second contact surfaces (31, 32) in contact.

The hedger trimming carriage and apparatus is a frame that is designed to be mounted on a vehicle. The frame of the hedger trimming carriage and apparatus is designed to carry during operation a hedger that is used to trim bushes and shrubbery while the vehicle is in motion. The hedger trimming carriage and apparatus comprises a mounting frame, a first hedger apparatus, and as second hedger apparatus.

A selection device for pruning machines is designed to select branches or sprouts for pruning performed by the pruning machine. The selection device includes at least one fixing portion adapted for removably fixing to a pruning machine. The selection device includes at least one actuator designed to exert a force upon the branches and sprouts, thus moving them to cause the branches or sprouts selected for the pruning to be arranged in correspondence to cutting elements provided in the pruning machine, hence at least partially preserving the other branches or sprouts from pruning. A frame is designed to at least partially support the at least one actuator. At least one regulating mechanism is fixed to the frame, is associated with at least one actuator, and is designed to regulate at least the direction along which a force is exerted by at least one associated actuator.

A hedge trimmer having a drive motor, a gear mechanism, and a blade arrangement with at least one cutter bar, which is driven in a reciprocating manner by the drive motor via the gear mechanism in a longitudinal direction. The blade arrangement includes a guide mechanism that extends over at least a part of the length of the blade arrangement. The guide mechanism is embodied as a molded part that includes a generally flat fastening portion and a profiled guide portion. The cutter bar is longitudinally movably held on the guide portion.
