Having thus described my invention, what I claim as new is: 1. In combination with a tractor having a frame with a depending front bolster structure including steering operating mechanism, a bolster assembly comprising a pair of cross bars bolted to the front of the frame, a vertical plate secured to the centers of the cross bars and extending therebelow, a bolster 10 bar secured to the plate and extending below the plate, an axle having its center bolted to the lower extremity of the bolster bar, steering knuckles on the ends of the axle, wheels 7 on the steering knuckles, arms extending from the steering knuckles, a connecting rod between the arms, an arm operatively connected with the steering mechanism and pivotally connected with the center of the connecting rod. V 2. In combination with a tractor having a frame with a depending front bolster structure including steering operating mechanism, a bolster assembly comprising a pair of cross bars bolted to the front of the frame, a ver- 5 tical plate. secured to the centers of the cross bars and extending therebelow, a bolster bar secured to the plate and extending below the plate, an axle having itscenter bolted to the lower extremity of the bolster bar, steering knuckles on the ends of the axle, wheels on the steering knuckles, arms extending from the steering knuckles, a connecting rod between the arms, an arm operatively connected with the steering mechanism and pivotally connected with the center of the connecting rod, said plate having a side flange along one side edge of the bolster bar.

3. In combination with a tractor having a frame with a depending front bolster structure including steering operating mechanism, a bolster assembly comprising a pair of cross bars bolted to the front of the frame, a ver-' tical plate secured to the centers of the cross bars and extending therebelow, abolster bar secured to the plate and extending below the plate, an axle having its center bolted to the lower extremity of the bolster bar, steering knuckles on the ends of the axle, wheels on the steering knuckles, arms extending from the steering knuckles, a connecting rod between the arms, an arm operatively connected with the steering mechanism and pivotally connected with the center of the connecting rod, a V-shaped brace having its ends fixed to the ends of the axle and extending rearwardly, a second V-shaped brace having its ends fixed to the frame and inclining downwardly and rearwardly, means pivotally connecting the apexes of the V-shaped brace.
