Earthmoving machine

In an earthmoving machine having a main longitudinal frame supported by wheels that are affixed to two longitudinally-spaced axles, said main frame having front and rear opposing ends and a longitudinal axis between opposing pairs of said wheels, a single elongated lift arm pivotably affixed to said main frame about a generally horizontal first axis adjacent said rear end of said main frame and extending generally therefrom along said longitudinal axis of said main frame toward said front end thereof, a cab with operator controls and a seat for an operator, said cab supported by said main frame and located adjacent said lift arm on a first side of said lift arm, the improvement comprising:

• an engine longitudinally supported by said main frame for providing operational power to said machine, said engine located on a second side of said lift arm opposite said cab;
• said cab including at least one window providing a horizontal and vertical field of view over said engine for an operator situated in said seat;
• a cooling mechanism for cooling said engine, said cooling mechanism comprising a substantially parallelepiped-shaped radiator having two substantially parallel major lateral faces, said lateral faces sloping outwardly and downwardly relative to said main frame at an angle greater than zero degrees with a horizontal plane through said first axis and located on said second side of said lift arm, above said engine such that said vertical field of view over said engine is greater than if said lateral faces were horizontal;
• an impeller mounted for rotation about a second axis substantially perpendicular to said lateral faces;
• and
• a casing supported by said main frame and enclosing said engine and said cooling mechanism, said casing having an air inlet grill adjacent to and above said radiator, and air outlet grills including one below said engine, said impeller positioned to move air through said casing along a predetermined path from said air inlet grill to said air outlet grills to cool said radiator and said engine.
