<P>PROBLEM TO BE SOLVED: To provide an electric tiller in which reduction of the battery capacity of a secondary battery can be easily grasped by an operator. <P>SOLUTION: There is no possibility of power source failure and the like in the middle of tilling work, as the residual capacity of a battery 48 is easily observed by bringing a display unit 26 to display a red color indicating that the electric capacity has been reduced when detecting that the difference of the voltages is less than a predetermined value and passing a predetermined time, by comparing the voltage of the battery 48 for feeding the electric power to an electric motor 8 for driving a rotary unit R for tilling a farm field, with a predetermined standard voltage. <P>COPYRIGHT: (C)2012,JPO&INPIT |
