The present invention relates to a steering device of an agricultural cultivator, comprising: In a state where axles (18, 20) are coupled to left and right coupling pipes (46, 48) of an axle sprocket (16) connected to an engine (14), respectively, balls (22, 24) are coupled to locking grooves (58, 60) of connection portions (54, 56) of the axles (18, 20) through a plurality of locking holes (42, 44) of the coupling pipes (46, 48), and clutch cones (38, 40) having concave grooves (70, 72) and support jaws (74, 76) are elastically installed at the left and right axles (18, 20) by springs (26, 28). When the locking jaws (74, 76) and the concave grooves (70, 72) selectively face the balls (22, 24) by a sliding operation of the clutch cones (38, 40) based on clutch hooks (34, 36) connected to an operation lever (32) of the handle (30) and elasticity of the springs (26, 28), power is transferred or blocked. In a state where axles (18, 20) are coupled to left and right coupling pipes (46, 48) ...
