  • Publication number: 20250204315
    Abstract: A front wheel driven robotic lawnmower is adapted to run in a forward running direction, the robotic lawnmower comprising a main body part, a plurality of wheels, a rotatable cutting disc that is driven by a cutter motor, and a control unit. At least two front drive wheels are drivably connected to a corresponding electric drive wheel motor that at least partly is contained in a respective motor housing. A corresponding frontmost part of the motor housings in the forward running direction define a front grass receiving opening, and a corresponding rearmost part of the motor housings in the forward running direction define a rear grass receiving opening. A shortest rear distance between the rearmost parts falls below a shortest front distance between the frontmost parts such that corresponding housing wall parts connecting the frontmost parts and the rearmost part form a funnel-shaped grass guide.

  • Publication number: 20240268259
    Abstract: 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).

  • Publication number: 20230270047
    Abstract: A self-propelled robotic work tool (1) is disclosed comprising a tool chassis (3) and a number of tool support members (61, 62, 63) attached to the tool chassis (3) and being configured to abut against a ground surface (27) in a first plane (P1) during operation of the work tool (1). The work tool (1) further comprises a number of snap fit assemblies (s1-s4) and a tool body (5) attachable to the tool chassis (3) via the number of snap fit assemblies (s1-s4). The number of snap fit assemblies (s1-s4) is configured to allow movement of at least a portion (5?) the tool body (5) relative to the tool chassis (3) between a lowered and a raised position in directions (d1, d2) substantially perpendicular to the first plane (P1) when the tool body (5) is attached to the tool chassis (3) via the number of snap fit assemblies (s1-s4).
