Abstract: A machine includes a seat assembly and a mechanical strut attached to the seat assembly. The mechanical strut, free of pneumatic seals, is positioned to move at least a portion of an armrest of the seat assembly along a horizontal axis. A length adjustment mechanism is movable to release a friction lock mechanism within the mechanical strut. The mechanical strut is telescopically movable through a continuous range of armrest lengths when the friction lock mechanism is released.

Abstract: A control console for a machine having a seat with a plane of symmetry is disclosed. The machine also has an armrest extending from the seat in a forward direction generally parallel with the plane of symmetry. The armrest has an upper surface intended to support an operator's forearm. The control console includes a base operatively connected to the armrest, and at least one operator interface device operatively connected to the base. The at least one operator interface device has a neutral axis inclined at an oblique angle relative to the upper surface of the armrest. The at least one operator interface device is pivotal in a fore/aft direction to initiate only a single function of the machine, the fore/aft direction being rotated outward away from the seat a predetermined angle relative to the forward direction of the armrest.
