The driver seat is secured to the cab wall with bolts
(35) and washers (36). The seat assembly consists of
a seat cushion (3) and backrest cushion (2) mounted to
seat frame (1). Seat frame (1) is attached to seat base
(34) by means of a suspension assembly. The air seat
only reacts when the driver sits on the seat. When
unoccupied, the seat sinks to the lowest position to
allow easier access.
