Abstract
The addition of emission control devices to engines of work machines has increased the cooling demands placed on the engine cooling system. This increased cooling demand can lead to the use of larger engine heat exchangers, thus requiring larger engine enclosures that may restrict the visibility of the machine operator. In accordance with one aspect of this invention, the engine enclosure of a work machine is devoid of an heat exchanger. An engine heat exchanger is mounted to a machine frame rearward of an operator cab and positioned so that an upper edge of the heat exchanger cooling core extends along a line that intersects the longitudinal axis of the machine frame at an angle other than 90°. This arrangement permits the use of a larger heat exchanger without substantially obstructing the view of the machine operator.
