Abstract: A control system for an excavator, the excavator comprising a movable arm, a movable excavator thumb and a tiltrotator attached to the arm, the tiltrotator being arranged to hold an auxiliary tool which is rotatable and/or tiltable by means of the tiltrotator. The control system is arranged to control the tiltrotator to rotate and/or tilt the auxiliary tool between a plurality of first positions and at least one second position. The excavator thumb is movable between at least one rest position and a plurality of work positions. The auxiliary tool is arranged to cooperate with the excavator thumb when the auxiliary tool is positioned in any of the at least one second position and when the excavator thumb is positioned in any of the plurality of work positions. The control system comprises a first blocker arranged to block the movement of the excavator thumb when the auxiliary tool is positioned in any of the plurality of first positions.
