The following disclosure relates to an improved system and method for harvester harvesting sod using a guide. Specifically, the sod harvester can comprise a front guide, a middle guide, and a back guide. The front guide can be capable of receiving a harvested portion of a grass strip. The middle guide can be connected to the front guide, and can be curved inward such that at least a portion of the guide is positionable under a conveyor frame. The back guide can be connected to the middle guide, and the back guide can be configured to horizontally displace the grass strip by moving the grass strip through the guides.
