ABSTRACT:
An improved, portable, lightweight vibrator which is an integral unit and is easily and quickly removably secured to a screed board to vibrate it. Only a source of electrical power is required to operate it. Virtually any 2.times.4, 2.times.6 or larger boards of wood or metal such as aluminum or magnesium up to 20 feet in length can be used as the screed board. When properly installed on the screed board, the vibrator will walk or pull the screed board toward the rough pour, to save time and labor in leveling concrete.
