Abstract
A wheel shield for a self-propelled sprayer includes a double wall plastic body with a profile designed to protect plants and provide smooth surfaces that resist build up of debris. A support and aligning rod assembly extending upwardly from the wheel hub includes locating pins to receive and initially support the plastic body so that mounting holes on the body sidewalls can be easily aligned with mating structure bracket structure on the wheel support. The inside wall of the body is connected to a bracket fixed to the wheel hub. A bearing is fixed to the outside wall of the body, and a mating hub mounting member is connected to the wheel hub. A bolt placed through the bearing and threaded into a nut fixed to the hub mounting member provides support for the body from the wheel hub without need for metal frames or similar supporting structure. The body terminates at a lower edge offset a substantial distance above the ground, and a flexible shield bottom is mounted on the lower edge to protect the body during shield contact with the ground or obstacles.
