A working machine (10) includes a working arm (12), the arm (12) in use, carrying a working implement (13), the arm (12) being raisable and lowerable about a generally horizontal axis (A) by a power operated device, a cab structure (16) for an operator, an engine (30) for providing power to a ground engaging drive structure (20) to drive the machine (10) over the ground and for operating the working arm (12), each of the working arm (12), the cab structure (16) and the engine (30) being mounted on a machine chassis (35), and the machine (10), said chassis (35) including a single primary chassis member (36) which provides a substantial resistance to torsional deformation of the machine (10) between the front (38) and rear (39) ends of the machine (10), the single primary chassis member (36) including a first part (40) which extends longitudinally of the machine (10) at the one side of the machine (10), and a second part (41) which extends transversely of the first part (40) at or towards one end (38,39) of the machine (10).
