Abstract: A work vehicle such as a tractor including a cooling fan (12a) arranged in front of the vehicle's engine main body (1), and is configured to feed air to the engine main body. The work vehicle further includes a DPF (19), which is arranged on one side of the engine main body and purifies exhaust gas exhausted from the engine main body, and an engine hood (7), which covers the engine main body, the cooling fan, and the DPF. An outside air intake port (21) is formed in both side surfaces of the engine hood at a position further forward than the cooling fan. On both side surfaces of the engine hood, a first opening (30) capable of exhausting air inside the engine hood in a direction away from the vehicle's operation seat in side view is formed in a position facing the DPF in the lateral direction.

Abstract: A guidance system for a mobile machine includes a location determining device for determining a location of the machine, a user interface and a controller. The controller is configured to receive location information from the location determining device, detect a path followed by the machine using the location information and, as the machine travels the path, receive waypoint information from a user via the user interface indicating a plurality of initial waypoints associated with the path. The controller is further configured to present the initial waypoints to the user, receive selected waypoint information from the user via the user interface indicating one or more of the initial waypoints as selected waypoints, and automatically guide the machine using the one or more selected waypoints.
