Abstract
Abstract A self-propelled vehicle having an enclosed operator cab in which the air intake pipe and the exhaust stack are mounted diagonally in line with one of the front corner posts of the cab so that although both the air intake pipe and the exhaust stack are close to the engine, they present a minimum of obstruction to the view of the operator. The portions of the intake pipe and exhaust stack visible to the operator are painted in the same dark color as the cab, in contrast to a lighter color employed on the rest of the vehicle. The vehicle may be provided with a hood which extends inwardly of the intake pipe and exhaust stack and is hinged to the vehicle at the front so that it can be tilted forward. The vehicle may be of the type which is articulated and in which the rear of the cab overhangs the rear section of the vehicle.
