ABSTRACT:
An improved quick coupler for attaching a tool to an excavator includes a body of a pair of spaced parallel plates providing structure for fixed attachment of the coupler to an end of the excavator. The plates define a first slot with an opening facing in a first direction to engage upon a first tool and a second slot with an opening facing in a second direction to engage a parallel second tool pin upon the tool. The body has a third plate between the spaced parallel plates. The coupler has a latch for securing the second pin in the second slot, the latch including a coupler gate rotatably mounted on an axis transverse to the second pin axis to pivot about the axis between a first position with the pin secured in the second slot by the gate and a second position with the gate clear of the second slot. A latch lever rotatably mounted on the coupler gate has a handle for moving the lever and a tab for engaging a third slot in the third plate. The latch lever pivots between a first position with the tab engaged in the third slot to resist rotation of the gate and a second position with the tab clear of the slot to allow rotation of the gate.
