A robotic work tool system comprising a robotic work tool, said robotic work tool comprising:
- a stationary hub and a rotatable shaft being supported by the hub, and
- a hub cover being releasably attached to the hub,
- wherein the robotic work tool further comprises a skid plate extending radially outwards from the hub cover,
- wherein the skid plate is arranged between the hub and the hub cover,
- wherein at least a portion of the hub passes through a plane in which the skid plate lies,
- wherein the hub cover maintains a fixed position relative to the skid plate and the hub when the hub cover is attached to the hub;
- and
- wherein the hub cover is also directly attached to the hub.
A robotic work tool comprising:
- a stationary hub and a rotatable shaft being supported by the hub, and
- a hub cover being releasably attached to the hub,
- wherein the robotic work tool further comprises a skid plate extending radially outwards from the hub cover,
- wherein the skid plate is arranged between the hub and the hub cover,
- wherein at least a portion of the hub passes through a plane in which the skid plate lies,
- wherein the skid plate is attached by a clamping action provided by the hub cover being urged against the hub such that the hub cover maintains a fixed position relative to the skid plate and the hub when the hub cover is attached to the hub, and
- wherein the hub cover is also directly attached to the hub.
A method for use in a robotic work tool system having a stationary hub and a rotatable shaft being supported by the hub, comprising the steps of:
- arranging a skid plate onto said hub, and
- attaching a hub cover to the hub whereby the skid plate extends radially outwards from the hub cover such that at least a portion of the hub passes through a plane in which the skid plate lies and the hub cover maintains a fixed position relative to the skid plate and the hub, and wherein the hub cover is also directly attached to the hub.
