Abstract: A sod harvester may include a cutting head for cutting the strip of sod from a field, a transport conveyor located behind the cutting head for conveying the strip of sod from the cutting head, and a roll-up mechanism operatively connected to the transport conveyor. The roll-up mechanism may be adapted to form the strip of sod into the sod roll. An accumulator may be disposed downstream from the transport conveyor. The accumulator may include a receiving surface to receive the sod roll from the transport conveyor. A guide member may be positioned above the accumulator. The guide member may be adapted to contact an outer surface of the sod roll when the sod roll is transferred from the transport conveyor to the receiving surface, thereby inhibiting unrolling of the sod roll.
