Abstract: An excavator tool attaching mechanism includes a housing having a pair of housing walls; a fixed engagement member for engaging with a first coupling pin of an excavator tool; a moveable engagement mechanism for engaging with a second coupling pin of the excavator tool; and a safety mechanism moveable between a locked and an unlocked configuration. The moveable engagement mechanism includes an engaging element moveable between a first position for releasing the excavator tool and a second position for engagement with the second coupling pin. The safety mechanism is automatically moved from the unlocked to the locked configuration by movement of the engaging element from the first to the second position, preventing movement of the engaging element between the second and first position. The engaging element is moveable to the second position when the moveable engagement mechanism engages with the second coupling pin.
