Abstract: A skid steer wheel mechanism including wheel axles rotatably disposed through axle housings which are securely mounted to the body or frame of the skid steer, and also including hub members which are cylinders with annular flanges centrally-disposed about the circumference of the hub members, and which is balanced upon pairs of bearings to equally distribute the weight and substantially abnormal wear to the bearings during the use thereof, each pair of bearings being spaced-apart inside the cylinder. The hub members are coupled to the wheel axles with disc-shaped coupler members having an internally-splined slot centrally-disposed in one side thereof and being adapted to receivably engage an end portion of the wheel axle.
