Abstract
A mechanism for mounting a wheel to a mower deck having a mounting arm carrying a bolt. First bushings fitted within the wheel rotate about a sleeve fixed to the bolt. Second bushings adjacent the first bushings transfer axial forces from the wheel to the mounting arm. The second bushing is recessed within the first bushings in one embodiment, and within the wheel in another embodiment. Seals are formed between the second bushing and the first bushing in one embodiment, and between the second bushing and the wheel in the other embodiment in order to keep dirt and debris from coming between the contacting surfaces during operation.
