Abstract
Quick coupling structure which is selectively connectible to a loader attachment and includes a spring-loaded latching pin located on the attachment and easily viewed from the operator station. A pin-contacting member located on the loader boom arm automatically releases the pin allowing it to move to a locking position as the attachment is rocked about a pivotal axis by an attachment cylinder. An alternate interchangeable coupling structure is provided which may be utilized on the attachment when a quick coupler is not needed, and the pivot points for the attachment remain the same with either the quick coupler or the alternate coupling attached. An attachment holder utilized with the quick coupler may be eliminated when the alternate coupling structure is connected to the attachment.
