A drum pulsatile for achieving agile and labor saving operation includes a base and an anchor rack located at the front side of the base which has an transverse upper rod located on the top section thereof. The upper rod is coupled with a rocking wheel which is fastened to a beater. The base has a rear end pivotally engaged with a pedal. The pedal has a front end fastened to a chain which winds around the front peripheral surface of the rocking wheel and has a distal end fastening to the rocking wheel. There is an elastic adjustment unit located on one side of the base that has an upper end coupling with the upper rod and a lower end movably connecting to the base thereby enables a drummer to step on the pedal in an agile and labor-saving manner at a faster speed to hit the drum.
