A plurality of spaced apart actuators are mounted to the frame. Each actuator has an actuator rod with a sharpened end which is movable between a first, retracted position and a second, extended position. The actuator rods have an insertion angle of approximately 60.degree. or less with respect to a contact surface such that upon actuation, the actuator rods are moved from the first position to the second position and the sharpened ends of the actuator rods are adapted to pierce the selected section of turf to firmly engage the section of grass turf to the frame for placement or replacement.
