Robotic lawnmower cutting deck with an angle adjustment arrangement, and a robotic lawnmower comprising such a cutting deck

Abstract

A robotic lawnmower cutting deck may include a cutting system which may include at least two cutters with a cutting disc and cutter motor. The cutters may be supported by a cutter support beam which may be supported at respective supporting positions by a first link arm and a second link arm. At each supporting position, the link arms may be pivotably attached to the cutter support beam with a corresponding first pivot pin and second pivot pin that may be fixed relative each other. The link arms may be pivotably attached to a frame part with a corresponding third pivot pin and fourth pivot pin, which may have an adjustable relation relative each other such that the cutter support beam may be rotated about a longitudinal beam extension when the relation between the third pivot pin and fourth pivot pin is adjusted.
