Abstract: A platform assembly is supported by the main frame and includes i) a framework, ii) an upper platform foot support secured to the framework and positioned adjacent to the doorway, and iii) a first stair member secured to the framework and spaced apart from the upper platform foot support. A stair assembly is movably attached to the framework and includes a second stair member. The door is movable between i) a first position in which the door is positioned to cover the door opening so as to block entry into the cab through the door opening, and ii) a second position in which the door is spaced apart from the door opening so as to enable entry into the cab through the door opening. The upper platform foot support, first stair member, and second stair member define a stairway leading to and from the door opening. A first plane intersects the upper platform foot support, the first stair, and the second stair. The first plane further intersects the door when the door is positioned in the second position.

Abstract: A crop sprayer comprises a cab having i) a left lateral wall structure including a first door, and ii) a right lateral wall structure including a second door. A first platform having a first foot support is positioned adjacent to the first door. A second platform having a second foot support is positioned adjacent to the second door. The second platform defines a routing space located beneath the second foot support. An exhaust assembly includes i) a muffler having a muffler inlet and a muffler outlet, ii) an inlet conduit in fluid communication with the muffler inlet, and iii) an outlet conduit in fluid communication with the muffler outlet. The second platform defines a forward platform portion and a trailing platform portion. The muffler is located within the routing space with the inlet conduit extending into the routing space at the leading platform portion and the outlet conduit extending from the routing space at the trailing platform portion.
