and (b) exerting an actuating force on one of the coupling element and the control cam element and thereby moving the coupling element relative to the control cam element and pivoting the second transport conveyor section relative to the first transport conveyor section from an extended position to a folded position wherein the second transport conveyor section is underneath the first transport conveyor section. ### Claim 2 (depends on 1) The method of claim 1, wherein: one of the coupling element and the control cam element is fixedly attached to its respective conveyor section, and the other of the coupling element and the control cam element is pivotally mounted upon its respective conveyor section. ### Claim 3 (depends on 2) The method of claim 2, wherein: in step (b) the pivotally mounted element moves in a circular path relative to its respective conveyor section. ### Claim 4 (depends on 1) The method of claim 1, wherein: in step (b), the second transport conveyor section pivots downwardly relative to the first transport conveyor section. ### Claim 5 (depends on 4) The method of claim 4, wherein: in step (b) the second transport conveyor section pivots approximately 180° relative to the first transport conveyor section. ### Claim 6 (depends on 1) The method of claim 1, wherein: step (b) further comprises moving the coupling element into a detent position of the control cam element and thereby locking the second transport conveyor section in the folded position. ### Claim 7 (depends on 6) The method of claim 6, further comprising: exerting a second actuating force on the one of the coupling element and the control cam element, and returning the second transport conveyor section from the folded position back to the extended position; and moving the coupling element into a second detent position of the control cam element and thereby locking the second transport conveyor section in the extended position. ### Claim 8 (depends on 1) The method of claim 1, further comprising: when the second transport conveyor section is in the extended position relative to the first transport conveyor section, carrying particulate material with the conveyor belt from the first transport conveyor section to the second transport conveyor section. ### Claim 9 (depends on 1) The method of claim 1, wherein: step (b) further comprises moving the coupling element through one cam section to lower the second transport conveyor section relative to the first transport conveyor section, and moving the coupling element through another cam section to pivot the second transport section to a transport position. ### Claim 10 (depends on 1) The method of claim 1, wherein: step (b) includes pivoting a lever attached to the first transport conveyor section, the lever having the coupling element thereon, and moving the coupling element along the control cam element, the control cam element being attached to the second transport conveyor section. ### Claim 11 (depends on 10) The method of claim 10, wherein: step (b) includes moving the coupling element from a first detent portion of the control cam element, through a second cam portion to pivot the second transport conveyor section downward, then through a third cam portion to pivot the second transport conveyor section upward, and then to a locking detent portion locking the second transport conveyor section in a transport position. ### Claim 12 (depends on 1) The method of claim 1, wherein: step (b) includes extending a hydraulic actuator and thereby pivoting the second transport conveyor section from the extended position to a transport position. ### Claim 13 (depends on 1) The method of claim 1, wherein: step (b) includes retracting a hydraulic actuator and thereby pivoting the second transport conveyor section from a transport position to the extended position.
