A seat for heavy equipment having a buffer in forward and backward directions, which can protect an operator by attenuating impact and vibration generated in a cab in forward and backward directions of an excavator in accordance with the driving of the buffer in a main working mode of the excavator. The seat includes a lower member mounted on a suspension plate, an upper member slidably mounted on the lower member in forward and backward directions of the equipment, a buffer unit for attenuating impact and vibration generated in the forward and backward directions of the equipment, a tilting unit, and a locking unit.
