Abstract
A forage blower having a frame with a wheel pivotally mounted on each side of the frame incorporates an improved adjustment mechanism for adjusting the blower unit in a plurality of vertical positions relative to the ground. The wheels are independently adjusted by the improved mechanism which includes an arcuate shaped downwardly facing bracket mounted on the frame and interconnected by a threaded rod to pivotal arm means which rotatably mounts the wheel. The lower end of the rod is threaded within a swivel nut which is rotatably mounted on the arm means. An engaging member, conforming to the arcuate shape of the bracket, is mounted on the rod below the bracket and positioned in mated relationship with the bracket such that the forces due to the weight of the blower unit are distributed over a large area thereby facilitating rotation of the screw threaded rod.
