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.degree..
This arrangement permits the use of a larger heat exchanger without
substantially obstructing the view of the machine operator.
