A telescopible discharge chute apparatus for a mobile concrete production machine is movable into a transport position located within the lateral confines of the concrete truck. The telescopible discharge chute apparatus utilizes individual chute sections that are substantially equal to the lateral width of the concrete truck such that the maximum effective length of the fully extended discharge chute is approximately twenty feet. One embodiment of the invention positions the generally vertical pivot axis for the discharge chute apparatus at a lateral side of the concrete truck to enable the transport width of the discharge chute apparatus to utilize the entire width of the concrete truck, while a cross conveyor is operable to transport the concrete mixture from a central, front discharge concrete drum to the discharge chute hopper. A second embodiment of the invention utilizes a half-sized chute section fixed to a central pivoted hopper to receive the concrete mixture directly from the central, front discharge concrete drum, while the telescopible discharge chute apparatus is slidable along the fixed chute section to enable the discharge chute apparatus to be placed into a transport position within the lateral confines of the concrete truck.
