The trigger (120) is movable between a first position (P1) and a second position (P2) with the trigger (120) being biased towards the first position (P1). A lock (130) is adapted to lock the trigger (120) at the second position (P2). The tool (100) is characterized in that the lock (130) allows the trigger (120) to selectively lock at one or more locking positions between the first position (P1) and the second position (P2).

The invention relates to a station (1) for a self-moving device (2), in particular lawn-care self moving device, comprising at least one support member, in particular wall (14), and at least one canopy part (10), wherein the canopy part extends from the at least one wall (14) and is configured for parking the self-moving device at least partially under the canopy part, wherein the station is provided with a water inlet (15) and water supply device (30) and an electrical power inlet (16) and an electrical supply device (32), the water supply device (30) and the electrical supply device (32) being configured for connecting the self-moving device (2). The invention further relates to a system (3) comprising the station and the self-moving device (2).
A handheld power tool (1) is disclosed comprising a power tool body (3), a tool (2), a power source (4) configured to power the tool (2), a switch (10) configured to set the power tool (1) in an active-state or an inactive-state, and an elongated handle (20). The elongated handle (20) comprises a trigger element (30) being arranged movable relative the elongated handle (20) such that the trigger element (30) moves relative the handle (20) when a person grips the handle (20). The switch (10) is arranged at the power tool body (3). The power tool (1) comprises a mechanism (7) operably connected to the trigger element (30). The mechanism (7) is configured such that a first mechanism member (11) of the mechanism (7) is moved in a direction (d1) towards the switch (10) when the handle (20) is gripped.
The present disclosure relates to an optical vegetation sensor unit having two or more light sources (17, 19, 21, 23) with mutually different light spectra, which illuminate an evaluated target surface. A photo sensor (25) measures reflected light from the target surface, and an amplifier circuit (51) processes the signal from the photo sensor, the amplifier circuit having a compensation input (63,65). The output from the amplifier circuit is measured when the light sources are wholly or partly turned off and a compensation signal is applied that drives the amplifier circuit output to a predetermined set point voltage. During measuring of reflected light, the compensation signal is applied to the amplifier circuit which substantially eliminates the influence of ambient light.

The present disclosure relates to a robotic lawn mower (100) having a first end portion (101) and a second end portion (102), and comprising a body (140), at least two drive wheels (130a, 130b), at least one swivelable wheel (131a, 131b), a rotatable grass cutting disc (160) having a rotation axis (152), and at least two electric motor arrangements (150, 165). At least two drive wheels (130a, 130b) have a drive wheel axis (145) with a center (146) and are drivably connected to a first electric motor arrangement (150), where at least one swivelable wheel (131a, 131b) has a corresponding swivel axis (153,154). A swivel attachment axis (151), running through at least one swivel axis (153,154) and being parallel to the drive wheel axis (145), is positioned between the second end portion (102) and the drive wheel axis (145). The cutting disc (160) is drivably connected to a second electric motor arrangement (165), wherein the cutting disc (160) at least partly is positioned between the swivel attachment axis (151) and the second end portion (102).
A reel assembly (100) for coupling within a housing (160) includes an axle (110) and a reel (120) defining a rotational axis (X-X'). The reel (120) is rotatably mounted around the axle (110) to allow winding of a flexible linear component (130) on the reel (120). The reel assembly (100) further includes a frame (140) which houses the reel (120). Moreover, the reel assembly (100) includes one or more fixing units (150) to removably fix the reel assembly (100) inside the housing (160). The reel assembly (100) is characterized in that the reel assembly (100) further includes a blocking mechanism (170) that operatively couples with the reel assembly (100) and cooperates with the reel (120) for selective rotation of the reel (120). The blocking mechanism (170) disallows rotation of the reel (120) in absence of coupling of the reel assembly (100) within the housing (160).
