Abstract
Operator enclosures or cabs in many cases have rear windows which are disposed in a generally upright or vertical position. The vertical position of the window reflects the instruments and dash as well as elements disposed forwardly of the cab during operation at night. The enclosure of the present invention includes a rear wall having lower wall portion and a upper wall portion. The upper wall portion is angled rearwardly from its lower edge to its upper edge and includes an opening for a window. A transparent window is sealably mounted in the opening and is thus also angled rearwardly at an angle sufficient to direct the reflection downward out of the operator's line of vision. This permits improved vision for the operator when operating in the dark.
