The invention discloses a steering upright column and a tractor applying the steering upright column. The steering upright column comprises a rack and a steering wheel (1) and also comprises an upper transmission shaft (21) connected with the steering wheel (1) and a lower transmission shaft hinged with the upper transmission shaft (21), wherein an upper sector tooth (3) is arranged on the upper transmission shaft (21), and a lower sector tooth (5) which can be matched and locked with the upper sector tooth (3) is hinged on the rack. The steering upright column is designed to be an upper steering upright column and a lower steering upright column, and the upper steering upright column and the lower steering upright column are hinged each other, so that a function of adjustable steering wheel angle is realized. The upper sector tooth is arranged on the upper steering upright column, the lower sector tooth is arranged on the lower steering upright column, the upper sector tooth and the lower sector tooth are mutually meshed, and locking of the upper steering upright column is realized after direction is adjusted, so that the steering upright column is normally used under the condition that the angle is adjusted, the disadvantage that the angle of the previous steering wheel of a tractor is fixed is avoided, and an operator feels more comfortable in use after the angle of the steering wheel is adjusted.
