Abstract: A drive system for a work vehicle comprises a control unit adapted to: monitor output of a speed ratio setting input device for a speed ratio setting request signal and output of a drive-request input device for a FWD-only request signal, determine from the speed ratio setting request signal if a requested speed ratio setting represented thereby is one of at least one predetermined speed ratio setting among a plurality of speed ratio settings possible for the work vehicle upon receipt of the FWD-only request signal, and, if so, output at least one control signal engaging a FWD-only mode enabling FWD operation of the work vehicle but disabling RWD operation of the work vehicle. An associated method is disclosed.

Abstract: 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 operations 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. The operators seat faces both to the front and to the right side. 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.

Abstract: A vehicle is provided with an operators cab having a heating system. The vehicle is powered by an internal combustion engine that is a source of heated fluid. Heated fluid from the engine is directed to a supply line where it is carried to a heat exchanger in communication with the interior of the operators cab. A valve having an electrical actuator regulates the flow of heated fluid through the supply line to the heat exchanger. A non-linear potentiometer controls the actuator so that the heat output of the heat exchanger is linear with respect to the operation of the control knob. The non-linear potentiometer drives the actuator so that the valve is opened at an increasing rate until it its fully opened.
