Abstract
A sod roller for automatically controlling the angular position of the end or flap of a roll of sod about the roll. A device senses the end, or trailing edge, of a strip of sod as a roll is formed on a roll-up conveyor. The sod roller holds the roll in the roll-up conveyor as it continues to roll and ejects the roll from the roll-up conveyor in a manner responsive to the position of the trailing edge of the strip of sod.
