Abstract
A quick attachment holder for connecting an attachment to the boom arms of a loader includes right-hand and left-hand end portions connected by a semi-rigid cross tube, without additional structural cross members. A pin connection of the holder end portions to the tube causes the left- and right-hand end portions to generally move together while permitting several degrees of relative rotational movement between end portions to aid in the reconnection of the attachment even when there is slight misalignment between the holder and the attachment. The cross tube is located on the pivot center of the holder so that only torque loads are applied to the tube. The pin connection will shear if the tube is accidentally over-torqued, and individual components of the holder are replaceable.
