PROBLEM TO BE SOLVED: To improve the strength and the efficiency in a steering link structure of a tractor. SOLUTION: In this tractor capable of being changed between a low floor specification and a standard specification, and having a constitution that front wheels are steered by connecting the front wheels to steering knuckle arms 35 connected to tips of cylinder rods 32a of hydraulic cylinders 32 for power steering through tie rods 33, a distance C between an intersection point of an axis O1 of the tie rod and an axis O2 of a fulcrum shaft 36 for pivoting the tie rod and the steering knuckle arm, and an intersection point of the axis O2 of the fulcrum shaft 36 and a axis O3 in the width direction of the knuckle arm is a length determined to be approximately half of a height A changed between the low floor specification and the standard specification, and the tie rod is connected to a lower part of the knuckle arm in the low floor specification, and connected to an upper part of the knuckle arm in the standard specification.
