Operator's cab for a work machine

A motor grader, comprising:

• a front frame;
• a rear frame disposed adjacent the front frame;
• an operator's cab disposed on the front frame, the operator's cab including a ceiling structure, a floor structure, a first vertical support bar, and a second vertical support bar, the first and second vertical support bars extending between the ceiling structure and the floor structure;
• and
• an operator's station in the operator's cab configured to position an operator in a driving position, a central region of the operator's station defining an index axis extending substantially perpendicular to a seating area of the operator's station;
• a first index angle defined between a longitudinal axis of the motor grader and a line extending from the index axis to the first vertical support bar;
• and
• a second index angle defined between the longitudinal axis and a line extending from the index axis to the second vertical support bar,
• wherein the first vertical support bar is disposed such that the first index angle is less than about 30 degrees, and wherein the second vertical support bar is disposed such that the second index angle is greater than about 70 degrees, and wherein the difference between the first index angle and the second index angle defines a viewing angle, the viewing angle being unobstructed by a vertical support bar.

A motor grader, comprising:

• an operator's cab having a ceiling structure and a floor structure;
• a chair disposed in the operator's cab and configured to position an operator in a driving position;
• a blade disposed forward of the operator's cab;
• and
• front vertical support bars extending from the ceiling structure to the floor structure, the front vertical support bars being disposed forwardly of the chair, and being spaced a substantially equal distance from a longitudinal axis of the motor grader, the front vertical support bars being configured to render both edges of the blade visible to an operator seated in the chair.
