Abstract: A retractable step assembly (400) for a cab (C) for a mobile machine includes a leg (450) slideably received in a through-hole (408) in a platform (58) of a cab (C). An upper end (452) of the leg (450) is fixed to a lower end (434) of a stretchable spring (430) whose upper end (432) is fixed. A step (470) is mounted to the lower end (454) of the leg (450). The leg (450) is movable between a retracted position and an extended position in which the step (470) is nearer to the ground than in the retracted position. The step (470) can be stepped on by an operator to move the leg (450) to the extended position to thereby allow the operator to exit the cab (C) by stepping on the step (470). The leg (450) can be unlatched by the operator in the cab (C) to return to the retracted position under action of the spring (430).

Abstract: A boom member (96) is pivotable relative to a platform (58) in a boom plane located intermediate the block ends of an engine (E) also mounted on the platform (58). The platform (58) with a cab (C) is rotatable by a turntable (46) 360° within the extent of a frame (12) moveable between adjacent rows of trees. The cab (C) includes corner partitions (23) extending between the front partition (228) and side partitions (226) at acute angles. A gullwing cover (200) is pivotably mounted to the platform (58) and has a ladder (208) extending over a cutout (204b) which extends over the engine (E) in an operating position and generally vertically in a service position. The air cleaner (71) is held in a spaced, parallel relation to the radiator (R) by its purge tank (65). The radiator (R) and a hydraulic heat exchanger (77) are in a spaced, parallel arrangement on opposite sides of the turntable axis.
