The Shake'n Rake™ provides a high speed powered up-and-down (shaking) motion that mimics the manual lofting of the sand that was formerly done by hand.  Using lithium-ion battery power, an integral reciprocating motor increases the lofting rate to up to 30 times per second.  The task of moving damp sand through a  screen can be accomplished without any manual agitation by the user, so fatigue is eliminated and productivity greatly increases! read more
