A secondary display unit (SDU) is also included in the premium cab option. The 7” (17 cm) SDU shows camera views, machine slope (fore and aft as well as side to side, in degrees), machine running temperatures, and light configuration. SDU is located on the corner B-post of the cab, this location is beneficial to operators when operating in the rearward seat position.

Tong view (located in the boom) is beneficial to operators when grabbing a bunch or drag, maximizing grapple usage and operator efficiency. Cameras can be viewed on both the PDU and the secondary display unit (SDU). Each display can toggle between the blade view camera and the tong view camera to accommodate operator preferences.
