PROBLEM TO BE SOLVED: To provide a tractor which satisfies a required precision and simultaneously reduces the locking number of an electric motor.
SOLUTION: In the tractor in which lifting or lowering switch control means for lifting or lowering an implement to a prescribed lifted or lowered position by driving and controlling an electric motor 25 according to the operation of a lifting or lowering switch lever 23 is provided, the lifting or lowering switch control means specifies the position of a motor operation member 24 on the basis of a pulse output from the electric motor 25 the motor operation member 24 is operated to a mechanical locking position on the lifting side, when the motor operation member 24 is operated on the lifting side according to the lifting operation of the lifting or lowering switch lever 23 the motor operation member 24 is operated to a predetermined prescribed position on the lowering side on the basis of the output pulse of the electric motor 25 when the motor operation member 24 is operated on the lowering side according to the lowering operation of the lifting or lowering switch lever 23.
