A turf conveying apparatus is positioned on the chassis below the turf carrying apparatus. The turf conveying apparatus is arranged to contact a substantial portion of the circumferential surface of the roll of turf so as to cause the roll to be unwound and conveying the turf toward the ground surface behind the driving tracks when driven.
