Abstract
An adjustable power steering mechanism to compensate for the adjusting of the tread width on the front wheels of a tractor. The tie rod is adjusted axially by a single adjusting device on the tie rod to extend or contract the tie rod to assure the same adjustment is made on the tie rod as on the front axle. A hydraulic actuator connected between a steering arm and a bracket on the front axle has a single adjustment to compensate for the tread width adjustments on the front axle and tie rod.
