A sod roll-out machine with endless tracks having a low center of gravity to prevent tipping on hills or inclines. The machine can be operated and steered by one person, wherein the roll of sod can be unwound in a forward or reverse direction. A pair of arms are elevated by hydraulic cylinders to facilitate the loading of a roll of sod to the distal ends of the arms, and to maintain the roll of sod slightly above the earth during the unrolling process. Due to the unique two track driving mechanism, the machine can be turned in place and operated in areas having limited accessibility. The tracks are driven by a motor, wherein each track can be individually controlled to be rotated in either a forward or reverse direction. A hydraulic pump is driven by the motor, wherein hydraulic fluid is provided to each of the hydraulic cylinders to control the elevation of each of the elevating arms. A cradle member is defined at the distal end of each arm for receiving a rod which is projecting out each end along an axis of a roll of sod. Hence, the loading and unrolling process is easy to perform. Large rolls of sod can be transported and unrolled thus minimizing the number of rolls of sod required to create a lawn. Further, the manual labor required by the operator is reduced as well.
