A first aspect of the present invention is a wheeled work machine (10) includes a rigid frame assembly (12) having a support (14) with a boom pivot (16). A front wheel assembly (18) is joined to the frame assembly (12) proximate the support (14), while a rear wheel assembly (20) is joined to the frame assembly (12) at an end remote from the support (14). The frame assembly (12) further supports an engine (24), operator platform (26) and cargo support (28). The operator platform (26) is supported by the frame assembly (12) between the boom pivot (16) and the engine (24), while the cargo support (28) is disposed behind the operator platform (26). The frame assembly (12) constitutes a second aspect of the invention, while a third aspect is the wheeled work machine (10) with or without the support (14) and a flat radiator (151) supported by the frame (12) at least partially behind the operator platform (26).
