1. A robotic work tool comprising a cutting disk, which is rotatable and height adjustable, the robotic work tool being configured to:
obtain a final desired cutting height of the cutting disk;
determine a first cutting height, based at least on the final desired cutting height;
raise the cutting disk to an elevated position above the first cutting height;
start a rotation of the cutting disk while the cutting disk is in the elevated position; and
lower the cutting disk to the determined first cutting height, in response to the cutting disk has obtained a substantially full rotational cutting speed.
