ABSTRACT:
The arrangement, in a first embodiment, comprises a cantilevered beam which is journalled at one end of a fixed shaft and journals another shaft on the opposite end. The fixed shaft, secured to the base of a machine, has a first sprocket integral therewith, the other shaft has a second sprocket integral therewith, and an endless chain is looped about and engaged with both sprockets. Also, the other, journalled, shaft carries a seat mount to which an operator's seat is joined. The arrangement accommodates for (a) a sluing of the seat, and (b) positioning of the seat in lateral dispositions in a same attitude, or orientation relative to the machine.
