A rolled turf layer including a main frame tube supported by a frame assembly adapted for installation on a three point hitch of a vehicle such as a tractor. A pair of slides or extension members are slidably mounted in the main frame tube with outer ends extending in opposite direction therefrom. A pair of rearward extending outside frame arms are rigidly secured to the outer ends of the extension members. Each frame arm rotatably supports a cone shaft carrying an inward facing turf roller insert adapted for insertion into the interior center of a turf roll. Each turf roller insert is rigidly secured its supporting cone shaft which extends through bearings in the associated outside frame arm. The left and right turf roll inserts are inward facing and opposite each other. An electrically actuated brake assembly is mounted on one frame arm and is operated by a control on the supporting vehicle. Manually operated controls are also provided for solenoid valves controlling operation of the left and right hydraulic cylinders within the main frame tube by which the laterally spacing of the left and right frame arms is adjusted.
