Abstract
A portable vibratory screed includes a blade that is connected to a handle constructed to be manipulated by an operator. Nodes of minimum vibrational amplitude are formed at specific locations along the length of the blade when the exciter is driven at a rated operating speed. A site level and/or the handle is attached to the blade at or in the vicinity of one or more of these nodes, therefore, is relatively isolated from induced vibrations.
