Abstract
A boom and boom cylinder quick coupler includes a body defining at least one bore about a transverse boom pivot axis, and the bore is adapted for selective alignment with a transverse bore defined in an associated boom. A first transversely extending open recess is defined in the body about a first transverse axis that is parallel to the transverse boom pivot axis. The first recess is adapted for selective receipt of a first pin affixed to an excavator. A second transversely extending open recess is defined in the body about a second transverse axis that is parallel to the first transverse axis. The second recess is adapted for selective receipt of a second pin affixed to the excavator. A boom cylinder quick coupler can also be provided. The boom cylinder quick coupler includes a boom cylinder coupler body that defines a bore about a transverse cylinder pivot axis so that the coupler body is adapted for pivotable connection to first and second associated fluid cylinders by insertion of a pin through the bore of the cylinder coupler body and through aligned bores defined in members connected to first and second associated fluid cylinders. First and second pin-receiving recesses are …
