Abstract
A combination wheel shield and ladder for an agricultural vehicle such as a sprayer includes a deformable plastic body with a profile designed to control the path of deflection and to return the body to original shape after deflection. The shield is mounted on a steel framework also designed to help control deflection and assure return to the original shape. A bail limits maximum shield deflection and increases the strength of the framework. A ladder is incorporated into a plastic wheel shield extension A combination handle-step structure located above the wheel and special platform structure located on the drop axle provide convenient access to the operator's station for all adjusted positions of the drop axle.
