ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention is directed to mounting controls in the right rear corner post of a work vehicle.
2. Description of the Prior Art
Work vehicles are designed to perform a work operation. Many work vehicles are designed to pull a large body behind the vehicle. Examples of vehicles designed to pull a large body, include logging skidders and agricultural tractors. It has been found that an operator of a logging skidder may spend sixty (percent) of his or her time looking forward and forty (percent) of his or her time looking rearward to check the log skidding operation.
Typically the operator controls for a work vehicle are located on a forward console so the operator can easily view and access the controls during operations. In addition, in combines and other agricultural work vehicles, controls and monitors are placed on the front corner posts of the operators cab. These front corner posts may form part of the roll over protection system (ROPS). In this way the operator can easily locate the controls and monitors, as they are not out of the operator's forward line of sight.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a convenient location for locating operator controls that are in the line of sight of an operator when operating a rear mounted work implement for dragging a body.
A work vehicle having a supporting frame and ground engaging wheels is provided with a work implement mounted to the rear portion of the work vehicle. The work implement is designed to drag a body behind the vehicle. The operation of the work vehicle is controlled from an operators cab mounted to the supporting frame. The operators cab is provided with a ROPS for protecting the operator. The ROPS is provided with four vertically extending supporting posts, left and right front supporting posts, and left and right rear supporting posts. An operators seat is located in the operators cab and is arranged diagonally to the longitudinal centerline of the vehicle. In the preferred embodiment, the operators seat faces both to the front and to the right side. In this embodiment, the right rear corner post is provided with at least one operator control that is in the line of sight of the operator when seated in the operators seat.
