摘要： A lawn mower wheel (2) is provided. The lawn mower wheel (2) comprises a hub (3) arranged for attachment to a lawn mower wheel axle extending in an axial direction. The lawn mower wheel (2)comprises a tread (4). The tread (4)has a tread width (8) in the axial direction. The tread is a web structure of material portions (6) separated by through openings (7) to reduce the area of the tread (4) onto which grass clippings may attach. The lawn mower wheel (2) comprises a rim (5). The rim (5) extends from the hub (3) to the tread (4). The rim (5) has a rim width (9) in the axial direction. The rim width (9) corresponds to less than half of the tread width (8), to allow grass clippings to fall from one through opening (7) of the tread (4) to another.

摘要： A sealing member (2), for waterproof sealing of a volume, comprises a hollow, generally cylindrical body and a sealing area (5a, 5b) at the respective axial ends thereof. At least one sealing area (5a) comprises a first radially extending portion (6) and a second portion (7) extending in a reverse direction partly overlapping the first portion. The second portion (7) has a free end and is arranged for pressing towards the first portion (6), thereby forming a seal with the first portion (6).
A sealing system comprises a sealing member (2) as above, a sealing seat (9) for abutment against the sealing member (2), and a counterpart surface (11), for pressing the sealing member (2) against the sealing seat (9). The sealing seat (9) comprises an inclined surface (10).
A work tool (1) comprising the above-mentioned sealing system has at least one sealing area (5a) of the sealing member (2) pressed between a housing (4) and a chassis (3) of the work tool (1).

摘要： The present invention discloses a folding arrangement (122) of a walk-behind power tool (100). The folding arrangement (122) includes a hinge (202) having a first hinge part (204) and a second hinge part (206). The first hinge part (204) is arranged for receiving an end of a first elongate member (118), while the second hinge part (206) is arranged for receiving an end of a second elongate member (120). Further, the first (204) and second (206) hinge parts are pivotally interconnected about a hinge axis (A), so as to enable pivoting of the hinge between a folded position and a closed position. Moreover, the first hinge part (204) has a first opening (212) arranged for passing through a cable harness (121) arriving from a channel or groove provided in the first elongate member (118). Similarly, the second hinge part (206) has a second opening (216) arranged for receiving the cable harness (121) arriving from the first opening (212). The first and second openings (212, 216) are facing each other when the hinge (202) is in the closed position. Moreover, at least one of the first (204) and second (206) hinge parts has a protruding portion (220), arranged for directing the cable harness (121) towards the first (212) and second openings (216) when the hinge (202) pivots from the folded position to the closed position. The application also concerns a handle assembly and a walk-behind power tool comprising such an arrangement.

摘要： The present disclosure relates to a lawn mower cutter unit (102) comprising a cutter propulsion unit (165) with a transmission axle (169) that is adapted to be rotated around a common rotation axis (Ax), a hub (166) that is rotatably connected to the transmission axle (169), a cutting disc (160), and a knob (120). The knob is rotatably connected to the hub (166) such that the knob (120) is adapted to rotate with the hub (166) and the transmission axle (169). The cutting disc (160) is displaceable along the common rotation axis (Ax), against a spring force of a spring element (130). The cutting disc (160) and the knob (120) are comprised in a coupling interface (140) that is comprised in the lawn mower cutter unit (102) and adapted to transfer a rotational torque transferred from the hub (166) to the cutting disc (160). The coupling interface (140) is adapted to releasably lock the cutting disc (160) in mutually separated positions along the common rotation axis (Ax) by means of the spring force, conferring an associated certain grass cutting height for each locked position.

摘要： A cutting blade (100) adapted to be carried by a tool holder (20) provided in a robotic work tool (10), the cutting blade (100) comprising a blade body (110) and a cutting edge (120, 121) extending along at least a portion of the periphery (111) of the blade body (110), and a circular hole configured to receive a pin (30) for attaching the cutting blade (100) to said tool holder (20). The hardness of the cutting blade (100) decreases in direction from the cutting edge (120, 121) towards the center (125) of the blade body (110) such that the hardness of the cutting edge (120, 121) is higher than the hardness of at least a center portion (126) of the blade body (110). The present disclosure also relates to a method for manufacturing a cutting blade.

摘要： A chainsaw (100) includes a power unit and a working assembly powered responsive to operation of the power unit. The working assembly includes a guide bar (120) around which a chain is rotatable. The guide bar (120) includes first and second side plates (200 and 210), a sprocket wheel (220), first and second shims (240 and 242), and a bearing assembly (230). The first and second side plates (200 and 210) face each other and extend away from a housing (110) to a nose. The sprocket wheel (230) is provided at the nose between the first and second side plates (200 and 210) and is rotatable about a hub (300). The first and second shims (240 and 242) are disposed between the first and second side plates (200 and 210), respectively, and corresponding ones of first and second sides of the sprocket wheel (220). The bearing assembly (230) is disposed between the hub (300) and the sprocket wheel (220) and includes a plurality of roller elements (320) made of a first material and at least one roller element (325) made of a second material that is different than the first material.
