A grain delivery conveyor (12) and a mechanism (16) easily and quickly configurable in a first manner for holding the conveyor housing (18) in a first position, and in a second manner for holding the conveyor housing (18) in a second position. The mechanism (16) is connected between the conveyor housing (18) and an adjacent structure or frame (50, 52, 68), and includes a first link (64) pivotally connected to the frame (50, 52, 68), and a second link (74) pivotally connected to the conveyor housing (18), the first link (64) and the second link (64) being pivotally connected at a pivotal connection (88). The mechanism (16) is configured such that as the conveyor housing (18) is in the first position, the first and second links (64, 74) will be in a generally aligned relationship so as to hold the conveyor housing (18). The conveyor housing (18) can then be released by pivoting the second link (74) from the aligned relationship. When the conveyor housing (18)is in the second position, the links (64, 74) will be in overlapping relation so as to hold the conveyor housing (18). The conveyor housing (18) can be released by pivoting the second link (74). The mechanism (16) can be operated with one hand, and can include a handle (82) for convenience.
