A system for disposing of a defective sod roll from a sod harvester is disclosed. The system includes: (i) a transport conveyor (ii) an accumulator located behind the transport conveyor, such that a gap is defined between a rear end of the transport conveyor and a front end of the accumulator and (iii) a movable tray located proximate to the gap. The tray moves between a retracted position and an extended position. When the tray is in the retracted position, the gap is open and a receiving surface of the tray is in a generally horizontal orientation. When the tray is in the extended position, the tray is located within the gap to receive the sod roll from the transport conveyor.
