A sod roll stacker assembles sod rolls on a platform member to form an approximately square layer of sod rolls. When the layer is complete, the platform is removed allowing the layer to fall on a support member below the platform. The platform is then moved to its former position. The above cycle of operations is repeated. The support member is rotated about a vertical axis through about 90.degree. after each cycle so that a stack of rolls is built up having the axis of the rolls in each layer at about 90.degree. to the adjacent layer, thereby increasing the stability of the stack.
