<p>A coupler for coupling an attachment to an excavator, the coupler including a pin detection system for detecting the presence of a attachment pin against a pin-engaging 5 surface in its pin-receiving recess, and means for indicating to an operator that the pin has been detected. The pin detection system comprises a contact member that is movable between a rest state and a displaced state. The system allows the operator to determine that the pin is correctly located in the recess before activating a latch to hold the pin. 0n a</p> |
