PROBLEM TO BE SOLVED: To provide a system for simple farm working capable of remarkably reducing physical and mental pains of an operator and epochally improving and increasing the operating efficiency and yield by making a rotatable operation carriage with a low table movable on a monorail-like straight tube freely placed in the ditch bottom of row spacing with strength of legs. SOLUTION: The system for the simple farm working comprises the operation carriage having a structure equipped with rash roller-shaped guide wheels with a derailing preventing groove before and rear of the lower center of a supporting frame for the low table, auxiliary wheels on both sides of the rearmost part of the supporting frame for the low table and the rotatable low table with a backrest in the upper center of the supporting frame for the low table. The operation carriage is placed on the monorail-like straight tube freely placed in the center of the ditch bottom of the row spacing. The system is provided with sliding plates for regulating capable of making the ground contact surfaces of the auxiliary wheels on both sides higher than the guide wheels in the center, the guide wheels having a smaller radius of curvature than that of the monorail-like straight tube and a handle capable of readily demounting the guide wheels from the straight tube when the forefront part of the supporting frame for the low table is lifted.
