ABSTRACT:
A connecting link for use on a bucket loader mountable on a tractor to control the pivotal movement of the bucket relative to the mounting frame to which the bucket is attached is disclosed wherein first and second members are telescopically associated to permit a varying of the effective length of the connecting link. A first pin is engageable through a first set of alignable holes through the first and second members to fix the telescopic position of the connecting link in an operative position. The first pin has a size sufficient to withstand the operating forces exerted on the connecting link during operation of the bucket. A second pin is engageable with the first and second members through a second set of alignable holes therethrough to shorten the effective length of the connecting link to a transport position and permit a rollback of the bucket for transport. The second pin has a size incapable of sustaining the operational forces exerted through the connecting link so that the bucket cannot be operated when the connecting link is in the transport position.
